From the trail junction with the Val Piora
trail, this segment passes through the Passo dell'Uomo (Pass of Man). The first mile follows a tumbling creek with several short waterfalls. At this point, you'll have a beautiful view of the entire Lai da Sontga Maria (Lake) below.
The middle mile is a very steep (250 m; 820 ft) descent on loose rocks with some ruts. With careful line choice and speed control, you'll successfully navigate to the shore of Lai da Sontga Maria. Or if you're the incredibly fit Swiss person I encountered, you may be able to ride up the trail. The final mile is an easy, flat section along the shore of Lai da Sontga Maria to the Passo del Lucomagno.
Since this section is mostly singletrack and given the beautiful scenery through which it passes, this is perhaps the best section of the Gotthardpass Section II
ride and indeed the overall long distance Gotthardpass route.
