‘Arzino sup’ touristically known as ‘Cascate e pozze turchesi del Torrente Arzino’ is a compact and rather aquatic canyoning tour in a remote Dolomite valley of glacier origin. The descent is characterized by a succession of leaps, pools, potholes and its inviting, colourful water straight from the source. Start of the obstacles are an almost horizontal geyser, a Niagara-pool, followed by a slightly more carved out gorge, but never more than 10m deep. Many obstacles can be jumped, bypassed or abseiled in the flow. Linking the upper & lower Arzino is the ultimate challenge in the valley, but can be done only with low to normal summer water conditions and experienced teams. The upper Arzino is more (beginner) friendly. Non-canyoneers can easily follow from the trail. Morning to mid-day for ideal light conditions. No phone reception in the upper parts of this valley.

Drive all the way up the Arzino valley, before the last hairpin turns take the left-hand secondary road that takes us higher into the Arzino valley than Arzino 0 starting point (there is one touristic sign for each of the canyons). Follow this little road which is quite narrow with lots of short turns, up until the P on the left hand side, marked again by a touristic sign.

From the car park walk down to the waterfalls. Start of the obstacles is near the picnic bench and a broken down viewing platform. Left of this viewing platform we can use the tree for abseiling into the first obstacle and find a first bolt left bank, as an intermediate anchor, from which an ideal access is given to the geyser.

01 - natural anchor on the tourist trail, left bank, 10m from a tree to a ledge (1p. only) 02 - 7m abseil, left bank, from a bolt on the ledge (exposed, 1p. only) into a waterjet-geyser (impressive when source is active) If the water is overflowing on all sides of this obstacle, the canyon is in high flow/overflowing. (01 & 02 are avoidable, but recommended to test the strength of the waterflow) Can also be jumped on the right. 03 - 8m abseil, from a natural anchor, right bank, 8m, into a Niagara-pool, can be partially avoided by abseiling left bank from a natural anchor. Or jumped from the right to the right of the pool (watch out, tree in the bottom centre) 04 - 6m left bank, before the bridge, bolt. Can be jumped into a more shallow pool. 05 - 5m right bank, directly under the bridge, bolt. Rocks below, no jump. 06 - 7m right bank, into a turbulent pool, bolt left & right. Jump left or right. 07 - 9m left bank, into a pool with water movement, bolt + ring. Jump to the right. Hanging pool with tourist viewpoint on the right (possible escape) 08 - 16m abseil, right bank, from a bolt w.ring 09 - 20m abseil, right bank, from 2 bolts (In 2026 there was a tree + undercurrent further down the pool, attention with high water) 10 - downclimb the sloping right bank, 5m 11 - MC with 1 intermediate bolt w.carabiner to a ledge, 2 bolts, left bank, to avoid the strong flow + water movement in pool below. Can also be abseiled + jumped straight into the pool. 12 - 5m abseil, left bank, 2 bolts. Possible games in the small pool with water movement 13 - abseil from a bolt + ring, left bank, 15m across 2 small pools. Exit of the canyon, right bank.

Exit at beach, right bank, hike up to the little bridge and take the trail up, 25' to the car. Or continue to Arzino inf. along the trail (few km).

Partially karstic, additionally some tributaries.
