Mer de Glace Ice Cave

The Mer de Glace Ice Cave is a natural ice cave located beneath the Mer de Glace glacier in the French Alps. Formed over centuries by the glacier's movement and melting processes, the cave features stunning blue ice formations and icy tunnels. It offers visitors a unique glimpse into the glacier’s internal structure and the effects of climate change. Accessible via a cable car and a steep walk, the cave is both a geological wonder and a popular tourist attraction, providing insight into glacial dynamics and the powerful forces shaping mountainous landscapes.
