France
Turquoise water slicing 700 metres into white limestone — Europe's Grand Canyon, vertigo included.
The water is turquoise. Not blue, not green — turquoise, the kind of colour you assume has been filtered until you see it in person. The Gorges du Verdon in France drops 700 metres from limestone rim to river surface, the white cliffs so sheer and close that kayakers crane their necks straight up to find sky. Eagles ride the thermals at eye level from the canyon road.
The Gorges du Verdon is the deepest canyon in France and one of the deepest in Europe, carved by the Verdon river through Jurassic limestone over 25 million years. The canyon stretches 21 kilometres from Rougon to the Lac de Sainte-Croix, where the turquoise river widens into a reservoir. The Route des Crêtes, a cliff-edge road built in the 1940s, follows the north rim with viewpoints that overhang the void. Rock climbing routes on the canyon walls range from single-pitch sport climbs to multi-day big-wall ascents. The turquoise colour comes from glacial rock flour — suspended limestone particles that scatter light in the blue-green spectrum.
Couple
The Route des Crêtes drive with stops at the belvederes, followed by a swim in the turquoise water at Lac de Sainte-Croix, makes a day that swings between vertigo and weightlessness.
Friends
Kayaking the lower gorge together, with 300-metre cliffs on both sides and swimming stops at every bend, is the kind of shared adrenaline that outlasts the trip.
