A 3- to 4-day route known as the Glacier Loop of the Vanoise is a must-do experience in the Vanoise National Park. This 60-kilometer trail starts in Aussois and winds around some of the most beautiful glaciers in the region, offering a high-altitude atmosphere that remains untouched by crowds. The starting point in Aussois provides the closest parking to the trail, which is quickly reached via the GR5 hiking path. The route begins with a visit to the eastern side of the glaciers, following the trail to the Arpont Refuge, with a 16-kilometer section that includes a 900-meter elevation gain. The second day continues in a similar fashion, but instead of descending to Leisse, hikers head north under the Réchasse Plateau to reach the GR55 path, which leads to the Vanoise Pass (and its refuge). Less experienced hikers can stop here for the day (14 km, +600 m) to avoid the more challenging parts of the trail, but those who wish can continue by descending the Arcelin Cirque and then ascending the stunning Grand Marchet Cirque to the Vanoise Pass. A new descent and a passage under the Petit Marchet lead to a final climb to the Vallette Refuge, located on a dramatic promontory (10 km, +1000 m from the Vanoise Pass). The final day is the longest (20 km, +1200 m), involving a journey southward past the Nants, Travers, and Rosoire Cirques, before ascending to the Aussois Pass. Hikers cross the pass and descend southward to reach the parking area. The ban on camping within the Vanoise National Park helps to preserve the trail from overcrowding, although the daily stages can still be quite busy during the day.
