Monument to Spanish Tour de France Winners and View of the Val d'Aran

Highlight • Monument

Each bend preceding the stele from Bossost honors one of the Spanish winners of the great loop up to the stele which recapitulates these victories. The point of view is worth making a small contemplative stop.

Tuc de la Clota Trail

Highlight (Segment) • Trail

Nice track to climb to the Portillon in Gravel/MTB mode. The part that goes over the pass remains quite flat for a while before actually starting the descent to Bossost. So, it's a nice spot to come and ride in the quiet mountains in family mode with children who are new to mountain biking, for example.

Portillón Pass

Highlight • Mountain Pass

The Col du Portillón is a short but intense mountain pass that connects the Aran Valley to France via a narrow, shady road through forests. Its ascent, with its pleasant slopes, is highly appreciated by local and professional cyclists.

Col du Portillon Signpost

Highlight • Mountain Pass

Col dur Portillon should not be underestimated, from Luchin it is short but the last 4km are hard and give no break

Portilhon Pass (Col du Portillón)

Highlight • Mountain Pass

Col du Portillon should not be underestimated. Although not as famous as its neighbouring cols, this col is hard and steep, specially on the last km
