Caves Furka (Eisgrotte)

The Furka Ice Grotto is a rare and breathtaking experience—an ice cave carved directly into the Rhône Glacier at the Furka Pass. Each summer, a tunnel is bored anew into the shifting glacier, allowing visitors to walk through shimmering blue corridors of ancient ice. The experience is surreal and beautiful, giving a direct view into the heart of a disappearing glacier. Though small, the grotto is a powerful reminder of nature’s beauty and fragility. With stunning mountain views along the Furka Pass, a visit to the Ice Grotto is both scenic and thought-provoking.

Perched high on the legendary Furka Pass, the Eisgrotte (Ice Grotto) offers a once-in-a-lifetime experience: stepping inside a glacier. Each summer, a 100-meter-long tunnel is carefully carved into the Rhône Glacier, allowing visitors to explore the translucent blue heart of one of the Alps’ oldest and most famous ice masses.

Walking through the Furka Ice Grotto is like entering another world. The air is crisp and cold, and the walls glow in hues of blue and white, shaped by millennia of compacted snow and ice. The tunnel leads into small chambers and side paths, some just tall enough to stand in, others shaped like shimmering halls. Every summer, the grotto changes as the glacier shifts, melts, and reforms—making each year’s experience truly unique.

What makes this visit even more meaningful is its fragile context. The Rhône Glacier, like many others in the Alps, is retreating rapidly due to climate change. Protective covers are even laid over sections of the glacier in an attempt to slow melting. A visit to the Eisgrotte is not only beautiful but thought-provoking—a glimpse into a natural wonder that may not exist in the same form much longer.

The grotto is located near the historic Hotel Belvédère, which offers an iconic viewpoint over the glacier and the sweeping Furka Pass. The scenic drive to get there is an attraction in itself, offering panoramic views of the central Swiss Alps.

Open typically from June to mid-October, the Ice Grotto is accessible to all ages and requires only a short walk from the roadside. It’s an unforgettable stop for travelers looking to experience the deep beauty and silent urgency of the mountains.
