And now for something completely differentÂ….

Is it silly? Perhaps. Is it nevertheless worth doing? Definitely. The exposure on this sheer, concave wall is incredible. Following the plastic is a straightforward yet, particularly in the final two overhanging pitches, awesome experience.

The route is 165 meters in length, with five pitches. You have to pay a small fee for the pleasure, which you do at the little restaurant at the top of the dam. That is also where you can get a key that unlocks a ladder youÂ’ll need to access the route (which begins a good distance off the ground).

The dam is at around 1400 meters above sea level, and is west-facing.

When you get to the top (final belay is the railing that runs across the top of the dam), you walk back across the damn to the restaurant, and back down the road to the carpark at the base of the dam.

More information and topos can be found in the Schweiz plaisir-sud or the SAC Ticino guidebook.


From Blenio, a small road provides access to Campo and from there on to Aquilesco. At Aquilesco a very small, windy road climbs up out of the valley floor and makes its way to the base of the dam, before continuing up to the reservoir above.


The route is very well protected with bolts.
When we came we discovered that a section of the only road leading up to the dam had fallen away due to an avalanche. It is, at this time, impossible to get up to the dam as construction crew work to rebuild the road.

It seems that a previous comment in November, 2016 indicated the road was closed. Not sure if it is because of the avalanche or not. Not sure when this thing will be fixed. From the looks of it, they aren't really close to done. Jun 21, 2017

I'm planning a trip to Switzerland in October and thought this would be a great stop. Anybody know what the weather is like this time of year? And anybody know if there are any places to stay nearby? I figure this is almost like a gym route. And my limit in the gym is 12a, but I normally climb no problem in the mid 11b/c range. Is this route doable, ya think? Aug 15, 2016

Be prepared physically. This is a long route. My arms were cramping so bad by the last two pitches that I could barely extend them. It took a good five minutes of shaking and stretching to get that lactic acid out after each pitch. Jan 10, 2011
