Damiano Rossini - Hi, it's the road that leads to Naret Lake, it's all paved and you can do it by road bike
Stefano Righetti - Hello John, Yes it is completely paved. Until Fusio less traffic. Road has 2 tracks. From the lake almost no Cars, road has 1 track. Very steep. Meteo is always Tricky and cold on top. Choose a Perfect day. Wonderful and Magnificent scenery on top. Go for it! Stefano
Matteo Frigerio - Hi, the segment is all about asphalt. You do everything in bdc. Go easy...
