La Morte is a mountain resort between Taillefer and Grand Serre, on the edge of Oisans. Alpe du Grand Serre is a year-round resort offering activities in summer, winter and the shoulder seasons. The area has several facets, including a swimming lake, climbing and biking options, and a trail showcasing historical heritage. You can also plan your stay around the conditions for each season.
Swimming lake and nearby activities
Plan d'eau de l'Alpe du Grand Serre is a swimming lake in the resort. Swimming is permitted, but there is no lifeguard supervision. Paddleboards and sun loungers are available on site for free. Access to the water and lifeguard supervision may vary by season; check the conditions before your visit.
Hiking trailheads, the Bike Park, the Via ferrata, a playground and a campervan parking area are all close to the lake. This means several different places for activities and stays are close together, without requiring the same itinerary. When choosing, consider which activities you actually want to do: at the lake, water access and the lack of supervision are important; other activities have their own seasonal or weather conditions.
Via ferrata, climbing area and Bike Park
The Via ferrata de la Cascade is suitable for children and beginners who are at least 1.30 m tall. Weather and seasonal conditions may affect the route, so take them into account when planning. La Cascade is also a natural site with starting points for hikes and via ferrata routes.
If you are considering climbing as a separate focus, La Morte is home to the La Cascade climbing area at Alpe du Grand Serre. It has 41 routes across three sectors, graded from 4 to 6b. The Bike Park is set among alpine pastures and woodland. There are opportunities to try downhill mountain biking or develop your skills. The trails’ opening times and conditions vary by season; check both before you ride.
Cultural heritage on the Circuit du patrimoine
The 3.8 km Circuit du patrimoine is a route for road cycling, walking, trail running and mountain biking. It passes historical landmarks such as bread ovens, a water-powered sawmill, traditional old houses, a chapel, memorial steles and a plaque commemorating Paul Mistral. The route brings together different traces of local history along a single circuit. Check trail conditions and markings on site before choosing one of the listed ways to get around.
The Chapelle Sainte Anne was founded in 1658 and is the only place of worship still standing in the municipality. It adds a historic site of its own to the heritage circuit. Together, the chapel, mill, ovens and memorials give the route a different focus from the resort’s sporting activities.
Getting here and planning for the seasons
The road journey from Grenoble to Alpe du Grand Serre follows the RN85, D1091, D113 and D114, as well as the Col de La Morte. Road conditions and possible closures may change, so check the situation before setting off.
Outside Zone A school holidays, the Car Région T93 runs year-round. In La Mure, connections are available on routes T90 Corps–La Mure–Grenoble and T91 Grenoble–Gap. In winter, the Transaltitude route runs directly between Grenoble and Alpe du Grand Serre. Check timetables and connections before travelling. It is also worth checking the individual activities when choosing when to visit: water access and lifeguard supervision at the lake may vary by season, the Bike Park’s opening and trail conditions depend on the season, and the weather and season may affect the Via ferrata.
