This remarkable natural site can only be admired after a 3½-hour round walk departing from Aulus-les-Bains. Surrounded by lush, unspoiled scenery, the 246-metre high Ars waterfall is absolutely stunning with its three separate drops. It is even more impressive in May and June when the snow is melting. Truly one of the most beautiful waterfalls in the Pyrenees!
