The Portillon Pass is one of the many smaller passes along the French/Spanish border. The pass has parts with almost-straights and long bends with a real good flow to it, which invites some sportier speeds. Beware though, as the safety on the pass is not that great (as almost always on French mountain roads): poor or nog safety barriers, sometimes pebbles/rocks, e.g. The other half of the pass exists of twisty mountain/forest roads with hairpins. Really funny piece of road.
