The Cirque de Gavarnie is the easiest of the area's three mountain amphitheatres to reach – and consequently the most popular – rewarding hikers with a panorama of spiky mountains that provides one of the Pyrenees’ most famous vistas. It’s especially dramatic after heavy rain, when waterfalls cascade down the mountainsides. The Cirque is about 1½ hours’ walk from Gavarnie village.
Between Easter and October you can clip-clop along on a horse or donkey (around €25 to €35 for a round-trip).
Be sure to wear proper shoes, as the trail can be slippery and rocky.
