A memorable road trip to Lake Lei
Lago di Lei is an artificial high mountain lake at an elevation of 1.945m (6,381ft) above the sea level, located in in the district of Hinterrhein in the Swiss canton of Graubünden.
Set high in the Valle di Lei, on the border of Switzerland and Italy, the road to the summit is totally paved but narrow in parts, with many tunnels. The last tunnel is pretty long with traffic lights and closed daily from 22 to 05h. The road was built in the 1950s.
There’s a parking lot at the end of the road. Access to the lake is typically open all year round, with the occasional closure in winters due to dangerous weather conditions. Starting at Innerferrera, the road to the lake is 8.0 km long. Over this distance the elevation gain is 477 meters. The average gradient is 5.96%.
