Getting there
Most visitors start via the Flégère/Index lifts to reduce the climb, then hike across to the lake. Strong hikers can also start from Col des Montets or Tré-le-Champ, but these routes can be more technical and exposed.
Local tips
- Start early to beat heat, crowds, and afternoon storms.
- Bring plenty of water and sun protection—there’s little shade at altitude.
- Choose the right route for your confidence level; don’t force exposed sections in poor weather.
- For the best reflection photo, aim for calm mornings and avoid windy days.
