Lac de la Plagne

The Lac de la Plagne is a mountain lake in the commune of Peisey-Nancroix, Savoie, at 2 144 m.

Can you swim here? Nobody says. The lake is not among the 43 declared bathing sites in Savoie — so no health monitoring, no rating, no lifeguard. And no official source we read either permits or forbids it. The Parc national de la Vanoise gives the general line: « il n'est pas interdit de se baigner… mais cela est fortement déconseillé » — not forbidden, strongly discouraged. We publish that silence rather than fill it.

You walk up. No road reaches the lake; you start from the parking de Rosuel, Peisey-Nancroix. The published figures for this route do not agree from one official source to the next — distance, ascent, time and even difficulty vary. They are given as found in this page's flags, with no average and no arbitration.

Parking is free. No official source says anything about accessibility here: neither accessible nor inaccessible — unknown. If your route enters the cœur of the Parc national de la Vanoise, dogs are banned — « même en laisse », not even on a lead — with a 135 € fine. The cœur status of this particular lake could not be established: ask the Parc before setting out with a dog.

This page is built on official sources and nothing else: the site's manager, the commune, the park, the tourist office, the national bathing-water register. Where two of them contradict each other, both are given and the gap is flagged — we do not choose for you. Where they are silent, the field stays empty rather than guessed.

In summer, when the shore is walkable. No official opening or closing date governs access to this lake.
