Located in the upper Blenio valley, the road to the dam, also known as Bacino di Luzzone, is paved, pretty narrow and with some steep sections. One wall of the dam currently features the world's highest artificial climbing wall.

The road has a high risk of massive rock avalanches. Starting from Strada Cantonale, the ascent is 3.8 km long with 10 hairpin turns. The elevation gain is 361 meters. The average gradient is 9.5%. Beyond the reservoir, a minor gravel road climbs up to Passo Muazz and Capanna Adula.
