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.

Beautiful climb up Col de Menté. Although not a really famous climb it is a beautiful one, with nice hairpins inside the forest and beautiful views at the end.
