Cirque de Gavarnie & Grande Cascade

A UNESCO World Heritage site, the Cirque de Gavarnie is a monumental natural amphitheater, carved by glaciers, boasting the Grande Cascade, Europe's highest waterfall (over 400m). Accessible via a well-maintained path (approx. 1.5 hours walk from Gavarnie village, mostly flat) or by mule-back ride in summer. There's a refuge-hotel at the base. Difficulty: Easy to Moderate, depending on the chosen route beyond the main path. Entrance is free, but parking in Gavarnie village is paid (approx. 5-7 EUR/day). The site is accessible year-round, though winter access requires appropriate gear and caution due to snow and ice.
