Little mountain pass that serves beautifully to cross the Pyrenees from west to east (or the other way around) without taking to bigger, straighter, faster roads. Nothing (very) special, but beautiful in itself. Narrow, not the best surface, animals on the road (and their droppings), but quite nice views. The eastern part (to/from Génos) is all hairpins between trees. Video of the route: going up from Estensan https://www.youtube.com/watch?v=Um_lXZY27pY (or search for col d'azet up) and the descent to the town of Génos https://www.youtube.com/watch?v=Tfn2zWJQHKw (or search for col d'azet down).
