A very vertical stream, ideal during rainy periods. With a good flow, the two large waterfalls of 50 and 60 meters will provide a good dose of adrenaline.

Downstream: reach the small village of Gerra (Gambarogno) and park at the beach parking area, right next to the stream (46°07'21.4"N 8°47'01.3"E), at a cost of 1 CHF per hour. Upstream: return to Via Cantonale, turn left crossing the bridge, then turn right onto the road that climbs up to Monti di Gerra. At Monti di Gerra there is a large parking area on the hairpin bend just before the barrier (46°07'06.9"N 8°48'03.2"E).

Approach: With shuttle: from the upper parking area, follow the flat path leading towards the alpine pasture, gain altitude with a couple of switchbacks, and exit the pasture in the direction of Monti di Sant’Abbondio. Ignore a couple of tributaries until you reach the main branch of the Gerra stream (46°06'37.9"N 8°47'58.7"E). About 25 minutes for 100 m of elevation gain. Without shuttle: from the lower parking area, first follow the paved road towards Monti di Gerra. At Cheventino, you can then take the trail to cut a few switchbacks. Once at Monti di Gerra, follow the same directions as for the shuttle approach. About 1h 30min for 630 m of elevation gain.

After the last vertical drop, there is a long stretch of walking along the streambed, about 800 m, until reaching a flood-control wall. Here you can enter the tunnel on the right and quickly return to the village and the cars. About 45 minutes for 250 m of elevation loss.

Flow assessment: directly at the valley parking area.
