The Gordolasque river flows into the Vésubie just below Belvédère. It descends from the Lac de la Fous at 2675m, (operated by EDF), and Lac Long to the north on the terrace of Gelas just inside the Italian border below the Cime de Gélas (3143m/).
This stunning and isolated, 19.7km/12.3m long, valley is accessed from Bélvèdere.
It winds up past a couple of hamlets and the Cascade du Ray before reaching the Pont du Gountlet and the desolate yet beautiful Lac du Basto. Here the road ends and a footpath leads to the beautiful waterfall named the Cascade d’Estrech.
Near St Grat, the Relais des Merveilles provides a place to stay. Above all it provides a starting point for one of the routes up to the Vallée des Merveilles.
