Grotte de Glace (Ice Cave)
Last updated:
Grotte de Glace Chamonix: A hand-carved tunnel inside the Mer de Glace, reached via the Montenvers train and gondola. It’s a memorable, chilly walk-through of glacier ice with changing sculptures. Seasonal access depends on weather and glacier conditions.
Quick answer
The Grotte de Glace is the famous ice tunnel carved into the Mer de Glace. You reach it via Montenvers: train up, then gondola down toward the glacier, followed by a long staircase—so it’s memorable, but not ‘effort-free’.
What to expect
- Walk through a carved tunnel inside glacier ice
- Seasonal attraction—opening depends on conditions
- Great ‘wow’ factor for kids and first-time glacier visitors
- Combine with Montenvers viewpoints and exhibits

Local tips

- Wear grippy shoes; steps can be wet or icy.
- Bring gloves and a warm mid-layer for comfort inside the cave.
