You can follow the bicycle path instead of the main road along Bregaglia valley. This way is longer but without traffic and visits very beautiful places crossing wonderful chestnut and fir tree woods:

1- Aurogo chestnut wood and S. Martino Church
2- Bregalone wood
3- Giavera wood
4- Brentan chestnut wood

The part between Promontogno and Soglio is the only one open to the traffic, but this is very limited. The rest of the way follows cycling tracks, mostly asphalted and the crossing of the main roads are always along tunnels or bridges (except in S.Croce and Borgonuovo if you choose the direct variant, useful on the way back).

Take a note:

- the final part leading to Soglio is not obligatory but, in any case, quite advisable.

-if you want a longer tour you can follow the Bondasca road departing from Bondo (1 hour).

- the passage of the creek after Brentan is quite peculiar. This follows a tunnel by a bend behind a waterfall.
