What Is a Marmot?
The Alpine marmot (Marmota marmota) is a large ground squirrel native to the European Alps. It belongs to the rodent family and is well adapted to life in high alpine environments.
- Scientific name: Marmota marmota
- Length: 40–60 cm (plus tail)
- Weight: 3–8 kg (before hibernation)
- Habitat: Alpine meadows and rocky slopes
- Altitude: Usually 1,500–3,000 meters
Marmots are known for their loud whistling alarm calls, which warn other members of the colony about potential danger.
Where to See Marmots in Switzerland
Marmots live above the tree line in open alpine landscapes. They prefer sunny slopes with soft soil suitable for burrowing.
Best Regions for Marmot Sightings
- Bernese Oberland hiking trails
- Above Interlaken
- Near Lauterbrunnen Valley
- Grindelwald First area (see First Mountain)
- High alpine trails around Jungfraujoch
- Valais region near Zermatt
In general, any alpine hiking route above 1,800 meters offers potential sightings.
Best Time to See Marmots
Season
- Late May to September
Marmots hibernate from roughly October to April. During winter, they remain underground and are not visible.
Time of Day
- Early morning
- Late afternoon
During hot midday hours, marmots may retreat into their burrows.
How to Spot a Marmot

Compared to topics discussed in dangerous animals in Switzerland, marmots pose no real threat.
What Do Marmots Eat?
- Alpine grasses
- Herbs
- Flowers
- Roots
During summer, marmots eat intensively to build fat reserves for their long winter hibernation.
Marmot Hibernation
Marmots hibernate for up to seven months. They live in underground burrow systems and survive winter by lowering their body temperature and heart rate significantly.
This adaptation allows them to endure harsh alpine winters.
Marmots and Alpine Ecosystems
Marmots play an important role in alpine ecosystems:
- Soil aeration through burrowing
- Seed dispersal
- Prey species for eagles and foxes
You can learn more about alpine biodiversity in Bernese Oberland flora and related nature guides.
Photography Tips
- Use a telephoto lens
- Stay quiet and patient
- Avoid sudden movements
- Shoot at eye level for better composition
Early morning light creates soft and natural images.
Marmots vs Other Alpine Animals
Marmots are sometimes confused with ground squirrels or young beavers. However:
- Marmots live in alpine areas
- They have a thick brown-grey fur
- They stand upright frequently
Unlike Swiss ibex, they are much smaller and live in colonies.
