Magnificent! A superlative, but no exaggeration: the Cirque de Gavarnie really is one of the most beautiful glacial cirques anywhere. A UNESCO World Heritage Site, its rock wall crowned by peaks over 3,000 m forms a stunning arc. The beauty of the rock is enhanced by water: the lovely mountain river on the valley floor and the famous 422 m waterfall. Far taller than the Eiffel Tower, it can be admired from afar and enjoyed close up, feeling its spray depending on the wind.
The walk is also easy, fairly short and family-friendly. Spectacular views without great effort.
Crowded? Easy road access and these attractions make it a must for anyone nearby. Paid car parks can fill early in summer, and you never feel alone on the route. However, the wide path keeps it flowing and pleasant, while car park capacity limits overcrowding.
