Starting point: loc. Serdes (San Vito)
Difficulty: medium-easy; steep, continuous ascent, paved road; steep, continuous descent.
Route
From Ponte di Serdes on the Boite river, enter the uphill road on the right (n. 436): it is a comfortable one-way asphalted road. After four hairpin bends and a wide bend, notice the unasphalted road on the left, closed by a barrier: this can be a change on this journey. Continue (the road becomes now binding) along the main road and after a series of hairpin bends you will arrive to Rifugio Larin (m 1213). Have a look at the majestic Sorapiss and Antelao. Remember that mountain biking isn't only hard work but it gives you the opportunity of admiring wonderful naturalistic sceneries too.
Continue for about 200 metres till a junction: from the left (not asphalted) you can reach the Rifugio Senes from where you can have a spectacular sight of mount Pelmo; from the right, after a false flat road of about 300 metres you will arrive to a place from where several paths wind. Keep the left and enter the descent that in few minutes will lead you to the bridge on the Boite river: follow that road and you will be back to the lake of S. Vito.
