Nestled within the Bernese Alps of southern Switzerland lies the Aletsch Glacier (Aletschgletscher) — a colossal river of ice that stretches over 20 kilometers long, making it the largest glacier in the Alps. With its stunning views, dramatic landscapes, and UNESCO World Heritage status, Aletsch Glacier is a must-visit for adventurers, nature lovers, and anyone seeking the raw beauty of alpine Switzerland.
Unlike some glaciers that are difficult to access, Aletsch Glacier is incredibly visitor-friendly, with a range of cable cars, hiking trails, and panoramic viewpoints that make it accessible to everyone — from casual tourists to expert mountaineers.
Aletsch Glacier lies in the Valais (Wallis) region of Switzerland, within the Jungfrau-Aletsch protected area — a UNESCO World Heritage Site since 2001. It originates near the Jungfrau mountain and flows down toward the Massa River valley.

Bring a wide-angle lens for glacier panoramas.
Sunrise shots from Eggishorn are particularly spectacular.
Use a polarizing filter to reduce glare on the ice and bring out sky contrast.
The glacier holds 11 billion tons of ice, enough to supply every person on Earth with 1 liter of water daily for 4.5 years!
Its retreat is being closely studied as an indicator of global climate change.
Aletsch Glacier flows at a rate of ~200 meters per year, though it’s slowly shrinking in length.
Take a train to Fiesch, Betten Talstation, or Mörel from Brig or Visp (well connected via SBB).
Continue via cable car to mountaintop villages or viewpoints.
Drive to the base stations at Fiesch, Betten, or Mörel
Large parking areas available at valley stations

While the glacier itself is a frozen wilderness, the surrounding region is rich in biodiversity.
Aletsch Forest is home to rare alpine flowers, ibexes, chamois, and golden eagles.
You might see marmots or alpine butterflies on summer hikes.
Preserved and protected, the ecosystem highlights the contrast between life and ice in the Alps.
The Aletsch Glacier is shrinking by about 50 meters per year. This retreat has significant implications for:
Water supply
Local ecology
Tourism and education
Interpretive signs and visitor centers help raise awareness of climate change, making the glacier not only a natural wonder but also a lesson in environmental stewardship.
Hiking boots (essential)
Layers of clothing (alpine weather shifts quickly)
Sun protection (high UV exposure at altitude)
Water & snacks
Camera or binoculars
Optional: Hiking poles, crampons (for guided glacier tours)
Aletsch Glacier is not just a destination — it’s a living, breathing marvel of the Alps. Whether you’re hiking along its rim, admiring it from a summit, or stepping onto its icy surface with a guide, the glacier leaves a lasting impression of awe and scale.
This unique blend of natural beauty, accessibility, and educational value makes it one of Switzerland’s most rewarding travel experiences.
