Lago del Narèt

Lago del Narèt, a steep road in Switzerland

Lago del Narèt is a high mountain lake at an elevation of 2.310m (7,578ft) above the sea level, located in Val Sambuco, Ticino, Switzerland.

The road to reach the lake is paved and was built in the 1950's. Drive at moderate speed. You’re not on a race. The views are outstanding at Lago del Sambuco and in the top section including the dam itself. While the profile shows a bunch of full kilometres at 10%, 11%, 12%, etc – there are some short stretches much, much steeper.

Starting from Bignasco at an elevation of 445m, the ascent is 32.12 km long. Over this distance, the elevation gain is 1.865 meters. The average percentage is 5.8 %. Beyond Lago Sambuco a long flat road takes you along the lake before the final climb to top starts. The narrow track keeps climbing steeply. It’s quite steep. Then near the top the road is fantastic, but also has a short descent before the dam itself. In the final few kilometres, there are three more small lakes before reaching Lago di Naret.
