21 May ZZ-032 Variant “San Mamés y Fuente Patro”
If you want to make the route a little longer, you can make a small loop along the track that goes up to San Mamés from Asín de Broto, and go down a section of the PR path back to Asín de Broto.
45% of trail. Hard uphill terrain and good for trial/mtb.
Almost all year round. There may be snow at the top part in winter.
Use ZTrails to follow the route.
