Cugnasco (inferiore): Inizio del canyon
2026-07-14: With Jenny (our first couples' tour)
2026-07-11: Very little water (1.5 stones were washed over).
2026-07-02: Beautiful, good water level
Avvicinamento: Alternative from the upper parking lot: From the upper (small and unpaved) parking lot next to the small one, follow the path for about 400 meters, first a short climb, then follow the saddle. Alternative On foot from the lower parking lot: about 45min. From the parking lot --> left up the road, after a few hairpin bends you will come to the sign 'Agarone' --> continue up the road --> at the next crossroads continue to 'Monti Motti' and always straight along the road --> here you will come to some nice houses and bus stops --> after a fountain (on the left) you will come more and more into the woods.) you get more and more into the forest --> at the sign 'Via Medoscio' at about 450Hm (parking) --> from here you leave the road and go right the trail through the forest a bit up --> then down to the stream at about 430Hm (entry).
Giro: In this canyon there is always something to do --> right at the beginning you have several rappel (jumps) --> the short distances between the rappel or jumps you have to overcome mostly climbing --> in this canyon there are many variants to master steps (waterfalls) --> in the upper half you come to a large overgrown boulder in the middle of the canyon --> here can also be bypassed left --> after a short climbing and hiking passages comes a beautiful approx. 30m waterfall (left in the water, re. outside of the water) --> after good control you can master the next parts by jumping or sliding --> be careful at the 18m slide (very steep/li. rock) (if you don't have enough practice it's better to rappel here!) --> after the pool on the left, rappel over rock for 4m --> again on the right. hold and rappel --> now comes another 7m jump and 10m rappel --> climbing passage in the water --> short swim --> rappel 8m right and20m left --> 3m jump left (! Caution) --> after a short swim it goes to the exit of the canyons which opens here and the bridge with parking comes into view. In 2022 all jumps were gravelled.

Cugnasco (inferiore): Parcheggio in uscita
Accesso: From Locarno --> Biasca on the right --> in the village of Cugnasco turn left after the bridge (right camping site) and park on the left before the next bridge or cross the next bridge and park at the mill collection point (= exit 240Hm) --> at the boulders lying under the bridge in the middle you can read the water level --> if 3/3.5 boulders are washed over the tour is still possible, if the 4th boulder is washed over, there is too much water in the canyon.
Ritorno: Get off at the barbecue area/ slide brake --> follow the path to the parking lot.

Cugnasco (superiore): Inizio del canyon
2026-07-02: The starting point for the Cugnasco Sup-Start is the end point of the SUP-SUP section. The exact coordinates are: 46.1900797N, 8.9163717E The location currently shown on the website/app is not the act...
2026-05-16: 4.5 stones washed over. Sufficient anchors available and most in good condition. Quite easy to walk.
2025-06-01: 4 rocks washed over, no problem for canyonists who know the canyon very well.
Avvicinamento: We continue along the dirt road and, after about 350 meters, reach the houses of Alpe Ronchi. Here, we take a few steps down the slope, then we see the signpost “Curogna 705” on a white background and a sign pointing right down toward “Cugnasco 1h”. This is where we’d come up if we only had one car available. However, we continue on level ground here, following the sign for “Monti Velloni 1h.” The trail leads into the forest, but after a few meters it veers left and uphill, while we take the faint trail that continues roughly level. We pass a stone house on the left and now follow the trail, which is sometimes eroded and barely visible, then clearly discernible again. After a ridge, we find ourselves high above the Valle di Cugnasco. We pass—in a somewhat exposed section—a small rock overhang, then continue downhill (with fixed ropes in some sections along the access). Where the trail abruptly exits in a narrow rock chute, we climb steeply down to the stream on the right side of the chute (it’s also possible to rappel down from trees). Blue dots mark the route during access.
Giro: The tour begins immediately with the highest and most impressive 55m waterfall (anchor left). After about 16m to the right of the watercourse (but practically in the fall line), there is a comfortable switch, from which you rappel the remaining 43m. This is followed by a small jump (S4). We jammed down the following chute a bit and then jumped. The next rappel (15m) leads left onto a wide ledge. If you want to avoid the following chute, you can take the anchor on the top left above the rock structure (approx. 20m). The following rappel from the block in the narrow chute (C8) can be unpleasant if there is a lot of water. But then you are soon at the last rappel. Here you reach the belay on the right outside the beam after about 8m (possibly with a redirection right above). From here you descend the last 25m almost dry. After about 300m we come to the entry into the Cugnasco inferiore, possibly our exit to the right and up to the parking lot at 450m above sea level. The path starts to the right of a large boulder that lies directly on the right bank.

Cugnasco (superiore): Parcheggio in uscita
Accesso: First as for Cugnasco inferiore: From the Locarno/Bellinzona road, turn off at the bridge over the stream in the village of Cugnasco and drive upstream on the left towards "Medoscio". 200 meters further on, in the parking lot on the left before the second bridge, you can park a car at the canyon exit if you want to add the Cugnasco superiore to the Cugnasco inferiore (450m above sea level). The road now winds steeply up the slope in hairpin bends. After the fourth left hairpin bend and the following right-hand bend, there is a small unpaved parking lot on the right. There are two signs opposite: "Via Medoscio" and a few meters further on "Sentee Colett" (park the lower car here if you only want to walk the upper part of the Cugnasco (450m above sea level). Continue uphill on the tarred road in the other car. After a left-hand bend and a longer straight section, there are 5 successive hairpin bends to the right and just as many to the left. At not quite 700m above sea level, we turn right after a detached house, pass the houses of the hamlet of Curogna on the north side, then keep left and park the second car about 400m after the turn-off (720m above sea level). The approach is also possible by bus, which runs approximately every 2 hours, with slightly shorter intervals in the morning.
Ritorno: Either as described above right up to the parking lot at 450m above sea level or at the exit of the lower parts right from the slide brake out to the road.

Avvicinamento: From the parking lot, walk to Via Malcarne and check the water level at the bridge. Continue uphill to the right on "Via In Cimalloco". When the road divides, keep left "Al Sasso Grande", there is another parking lot on the right. The hiking trail begins just behind it, which you now follow. Above the houses, the path is marked with a blue arrow and wave signs. Turn left twice to reach the bridge.
Giro: The tour is scenically surprising due to the many palm trees that grow in the middle of the canyon. This is probably why Luca Nizzola named the canyon Ri delle Palme. The ground in the stream is very slippery! T3 C5 C12 Mc 4 C45 R6 C6 T3 S4 T3 Mc 3 C30 T2 T3 T4 C12 C16 C8 + C24 (stand around the corner, out of the water behind the corner) C17 C24 (t4)

Commento: Ebenfalls Parkmöglichkeit
Idrologia: As some rappelling routes lead right through the waterline, it is essential to check the water level carefully before the tour! Checking the water level: If you leave the main Bellinzona-Locarno road in Gudo, turn right at the "Cottini" restaurant and continue in the direction of "Cantina Ramelli", you will cross our stream. The steps below the bridge may be flooded to a maximum height of 5 cm.

Avvicinamento: From the parking lot, take the road above the cemetery to the right to the church (Santa Maria del Castello) --> behind the church, a steep pilgrims' path leads up next to the already visible canyon --> follow the steep path and pass the houses on the right (parallel to the canyon) --> after the last impassable steep section, there is a slightly sloping path (sloping terrain, here you can save yourself the first rappel by slipping and get a helicopter flight to the hospital) up to the entry at approx. 460 m above sea level. The last few dozen meters are equipped with a rope traverse, the quality of which is not always the best.
Giro: Arriving at the first pool at approx. 450m, you immediately start rappelling in the water --> via a traverese rope that can be pulled off you reach the first rappel point of approx. 30m with a sharp edge --> after this point the canyon immediately becomes narrower --> 2 approx. 15m rappels follow, the 2nd of which leads through a narrow channel (problematic when there is a lot of water) --> this is followed by 25m and 20m rappels into a large pool --> now the canyon opens up. The second leads through a narrow chute (problematic when there is a lot of water) --> followed by a 25m and 20m rappel into a large pool --> now the canyon opens up --> here you have the possibility to get out on the right (small swimming pools) --> via a traverese rope that can be pulled off you reach the chain anchor --> from there you have a view of the beginning of the narrow C50 waterfall (slippery, high water pressure and small pool!!!!, not visible from above!) --> the next part is again narrow and unclear, the water shoots down in zig zag 25m into a small hollow (very nice) --> the canyon opens up again and you could already get out here --> there is another slide or jump of up to 20m (but the big pool is only deep enough on the right side --> the next parts are unproblematic --> at the end you jump about 8m into the swimming pool at about 280Hm.

Accesso: From the highway junction north of Bellinzona, take the N2 towards Biasca. Via Claro and Cresciano you come to Osogna (11.4 km from the highway to the bridge over the Nala). After the Nala bridge, drive to the cemetery and park your car there. Please do not park in the town center, there have already been many complaints and the locals have agreed with the administration that only the parking lot at the cemetery will be used for canyoning. If this parking lot is full, there is a long parking strip 350 meters further on which is also designated as a public parking area. GPS 46.3159720, 8.9831842

Check the water flow, then cross the riverbed to the south and hike along the narrow mountain road to the beginning of the trail to Pönt and Valle di Osogna. After the steep climb to Pönt, the trail flattens out and then enters the Valle di Osogna. At the bridge at 839m the entry starts.
Giro: Between C27 and C19 danger of falling rocks. Highlight of the part is the very narrow cut C23. If the water level is too high for tour participants, one must go through and below set up a rope ferry (then at least 35m of rope required, anchors are available).

Avvicinamento: On foot: Walk along the road above the parking lot towards the river and descend to the large terminal basin. Check the water flow, then cross the riverbed to the south and hike along the narrow mountain road to the start of the path to Pönt and Valle di Osogna. After the steep ascent to Pönt, the path becomes flatter and then enters the Valle di Osogna. From bridge 839, the path climbs again. At stone bridge 950, carefully check the water level in the basin below (this can become a trap). Climb the steep steps and at 1060 meters take the less visible path on your left down into the valley to the river and the outlet of the diversion channel. Helicopter: From the helipad, first go up to the houses I Cassin di Carli. There we take the hiking trail to the right. After the last houses, the path descends along a ridge. At an altitude of 1060m, we take the not very clearly recognizable path to the right. It leads us down to the entry at the outlet of the drainage channel.
Giro: The upper part starts after the water intake and accordingly carries little water. The water is generally quite cold. Many slides that need to be well checked out. There are also some possible jumps.

2025-10-14: High abseils, some rock friction. Slippery. Nice views over the valley! Waterlevel low at the moment.
Avvicinamento: Next to the final waterfall, turn right orographically up a small path. Cross the bridge and now orographically left on a marked path always close to the stream up to the vicinity of a house (Cantoi - 645 m a.s.l.). Here you climb to the foot of the high waterfall to the entry into the lowest part of the Froda (600 m above sea level).next to the final waterfall orographically right on a small path steeply up to the stone bridge. If you want a flatter, easier path, you can also start at the church in the village (Ciesa Pietro e Paolo) --> see Start Intermedio; from there in the direction of Santa Petronilla (= stone bridge). Now ascend orographically left on a marked path always close to the stream until near a house (Cantoi - 645 m a.s.l.) (here you could already descend to the stream if you want to skip the 70 /115 m sequence). Continue along the path until after a hairpin bend a path branches off to the left (approx. 790m); follow this for a few more minutes until you reach the stream at 770m.
Giro: If you are looking for a very vertically demanding canyon, this is the right place for you --> work carefully with the rope and always give enough rope (some of the edges are very sharp) --> essentially you have a breathtaking view throughout the canyon --> be careful in the lower part (after the stone bridge) --> danger of falling rocks due to rope retrival or bathers.

Avvicinamento: Initially as for Val Gr. inferiore: from the parked car on the path continue upstream, keeping right through the property of a "collector" and on a bridge over the creek. After the bridge, go up on the tarred road. This crosses the Val Grande again. Where you reach some houses, you go up on a mule track under chestnut trees on the right towards Salvabella - apparently a kind of Calvary path. At a prominent bend to the left (520m a.s.l.), a path branches off to the right under trees, signifying the beginning of the descent to the entry to the lower part of Val Grande.\But we continue up the main path, passing the few houses of the hamlet of Dömna (60m a.s.l.) and at 765m a.s.l. we come to a fork in the path with a signpost: we follow the instruction "Cortascia, Chiegg" to the right and at 800m a.s.l. we reach the stone bridge over our stream - in front of it on the right a somewhat larger wayside shrine. To the left of the bridge, a chute leads down to the entry.
Giro: Arriving at the stone bridge (approx. 770m) you can immediately enjoy the wonderful view --> to make the descent into the stream before the bridge left safe, a rope should be set up on the railing approx. 15m --> then it starts immediately with the rappels in open terrain R4, C37, C25, R30, R26 --> over the next small steps you can slide or descend --> then follows a rappel left approx. 27m before it gets narrower --> in the narrow place is left approx. 5m rappel (large jammed tree) --> several uncomplicated rappels follow in between short walking passages and small climbs --> when you reach the large boulders you have the option of taking the emergency exit on the left --> after the rock arch there is an inflow on the left and a large clamping block with the key point C26 on the left (the arrival pool is narrow and turbulent - -> dangerous if there is a lot of water)-> dangerous if there is a lot of water) --> after this breathtaking place there is a small narrow passage --> the next abseils are no longer difficult --> in between there are always walking and downclimbs --> at the end of the superiore the terrain becomes flatter --> at an open point (slight left bend) you have an exit at approx. 450Hm right the exit.

Ritorno: At about 450Hm there is a steep exit or access from the canyon on the right --> once at the top, turn left and return to the trail that has already gone up --> follow it to the parking lot --> 2nd option: via Val Grande to the trail that has already gone up --> follow it to the parking lot --> 2nd option: descend via Val Grande inferiore (2-3h).

Avvicinamento: From the parked car on the path further upstream, keeping right through the estate of a "collector" and on a bridge over the stream. Here you can easily see the last part of the descent. After the bridge, go up on the tarred road. This crosses the Val Grande again. Where you reach some houses you go up on a mule track under chestnut trees on the right towards Salvabella - at the same time apparently a kind of Calvary path. At a prominent bend to the left, a path branches off to the right under the trees. But leave it after a few meters to the right and on unclear tracks steeply down to the stream (entry). Description if you park at the barrier: From the barrier approx. 50m to the first small stone bridge (water level check!) --> then along the road over iron bridge with wooden beams up to right small stone house with hiking mark --> past behind the house over small wooden bridge --> past small chapel --> further up again small wooden bridge and house with stables --> up again. Wooden bridge and house with stable --> now it's only a few meters until a trail mark on the rock and right. a tree with a hole in the middle show the way to the streambed (450Hm) --> after a short distance descend via rope traverse into the streambed.
Giro: After the entry come 3 small pools with short slides --> 20m rappel left or 7m rappel and 8m jump (!) --> very nice 30m rappel in large pools --> from here the canyon is somewhat narrower --> there are several rappels that are always well visible by fixed ropes or in more water alternatives open --> who high jumps in deep pools comes in this canyon at his expense --> at the end you come back to the stone bridge where another beautiful 20m rappel with a 5m slide crowns the conclusion.

Accesso: Coming from Locarno, turn into the Maggia Valley at Ponte Brola. After about 4.5 km, cross the stream coming from Val Grande and, immediately after the bridge, turn right onto a dirt road. This is followed to its exit, the last meters across an agricultural estate. Now on the side of the road above the stream park car. An alternative access is via the tarred road that leaves to the right before the bridge. Park here in front of the barrier in a suitable place.
Ritorno: After the slide right up over stone bridge to the road (parking lot).

Iragna (superiore): Inizio del canyon
2026-07-11: Our CE4Y 75m got stuck in the C20 before the C27 and we left the rope there. If anyone retrieves it, please let me know
2026-07-10: Overall: a beautiful canyon with great slides and jumps; very slippery in places.
2026-05-25: Very nice, a little slippery. Avoided the penultimate slide due to the water current.
Avvicinamento: By car the access is shortened to 20min --> from the parking lot you go back to the serpentine curve and continue the slightly sloping path through the mountain village "Citt" --> at the signpost continue to the left in the direction of Pön --> after a few minutes there is another fork --> here right down to the stone bridge --> entry at about 730Hm. If you do not have a shuttle car, you can take the footpath from the village of Iragna, which leads up to the entry in about 1.5 hours.
Giro: The Iragna superiore is one of the most beautiful canyons in Ticino --> the upper part can be well combined with the intermedio --> the water level should be checked before the very aquatic canyon, absolutely --> below the bridge is r the first and highest abseil (36m) which leads directly in the water course, into the breathtaking scenic landscape --> technically demanding rappels alternate with jumps and short walking passages --> a rope traverse is often needed to safely reach the exposed belay stations (there are plenty of pitons for this purpose)--> most of the jumps require a good jumping technique and control of the water depth in the pools --> the current should not be underestimated --> at the trickiest points, it is usually possible to rappel outside of the water flow --> if you only want to walk the Iragna superiore, look for the exit at approx. 510Hm left the exit over the slope (open canyon section before the next rock face and downclimb) --> in most cases, however, the Iragna intermedio is done at the same time (short part) --> if you also decide for a part or the whole Iragna inferiore, time and equipment should be considered!

Giro: Wild and attractive canyon for experienced canyoneers. Walk with as little water as possible.\nAt the abseil point in the chute, which is about 15 m long and the end of which cannot be seen, be sure to traverse along the edge to the right to the intermediate level not yet visible from the first abseil point!\nIn general, the ascent of the lower part is connected.

Giro: From the beginning you already have a very impressive view --> the first small pool you can slide (depending on gravel or stones) --> then follows immediately the approx. 40m waterfall (very slippery and sharp edges). This place can also be rappelled left 45m (!) outside the water (reachable via rope traverse) --> two short slides (flat) --> C22m downclimb (can also be rappelled outside the water) --> downclimb --> stone bridge --> short rappel or jump (5m) --> narrow channel (! Slippery) --> downclimb right about 20m (final part can also be rappelled) --> downclimb --> 2m downclimb right --> jump 6m (or rappel) --> final waterfall about 15m (very slippery, sharp edge) --> depending on the depth of the gump the last 2 places can also be rappelled (also possibility to rappel).
