FAQ

When to see marmots in Haute-Savoie? Marmots are active from April to October, with a peak of observation in the morning and late afternoon. They hibernate the rest of the year and remain invisible in winter. In summer, they are particularly visible during the hottest hours of the day, when they bask in the sun on the rocks.

Where to easily see marmots, without hiking? Col des Aravis and Col de la Colombière are accessible by car and allow you to observe marmots just a few minutes’ walk from the parking lot. Parc de Merlet offers guaranteed observation without effort, on marked trails suitable for families.

Why do marmots whistle? The characteristic whistle of the marmot is an alarm call issued to warn the rest of the colony of danger, such as the approach of a bird of prey or a hiker too close. Hearing this whistle usually means the marmots have spotted you before you see them.

Can we feed the marmots? No, it is not recommended to feed marmots. Their diet is strictly adapted to their natural environment, and feeding them can disrupt their behavior, make them dependent on humans, or harm their health.

What is the difference between a marmot and a stoat? The marmot is a stocky rodent, weighing several kilos, living in colonies in burrows and hibernating in winter. The stoat is a much slimmer and elongated mustelid, with brown fur in summer and white in winter, which remains active all year and hunts small prey. Both species frequent the same massifs of Haute-Savoie but rarely meet in the same places, the marmot preferring open alpine pastures and the stoat rocky or wooded areas.
