The Lac du Lauvitel trail in the Parc National des Écrins leads hikers to one of the most pristine glacial lakes in the French Alps, at an altitude of approximately 1,530 metres within the Écrins National Park in Isère, Auvergne-Rhône-Alpes. Designated a national park since 1973, the Écrins protects over 918 square kilometres of high-alpine terrain including France's southernmost glaciers and some of the most biodiverse sub-alpine meadows in Europe.
The trailhead begins near the hamlet of La Danchère in the Vénéon valley, a 30-minute drive from the base town of Le Bourg-d'Oisans (38520). Le Bourg-d'Oisans is accessible by bus from Grenoble on the VFD line (approximately 1 hour 15 minutes, approximately €3.50 / approx USD 4), though a hire car is recommended for reaching the trailhead directly. Parking is available at the trailhead car park near La Danchère. No national park entry permit is required, but the park's strict no-dogs rule is enforced throughout and fines apply.
The 10-kilometre return trail climbs 850 metres on a well-maintained mountain path through mixed conifer forest, sub-alpine juniper scrub, and open rocky terrain above 1,300 metres. The surface is compacted earth and rock with stepped stone sections installed by the national park service. The upper section above 1,400 metres transitions to open rocky slopes with limited shade; the lower forest section provides consistent shade in the morning hours. No significant exposure or scrambling is required, making this a legitimate mountain day walk for hikers with solid fitness but no technical skills.
The lake sits in a glacially carved cirque backed by the northern cliffs of the Écrins massif, which rise a further 300 metres above the lake surface. On calm mornings the water reflects the surrounding rock faces with exceptional clarity. Camping around the lake is prohibited to protect the shoreline vegetation. The nearest mountain hut is the Refuge du Lauvitel (staffed in summer, approximately 15 minutes beyond the lake). Water from the lake outlet stream is potable but should be filtered.

Tips for visiting
- Dogs are strictly prohibited throughout the Parc National des Écrins — this rule is enforced with fines and visitors arriving with dogs will be turned away at the park boundary
- Carry 2 litres of water from the trailhead; the lake outlet stream is the only source on the trail and filtration tablets are advisable
- Snow can persist on the upper section of the trail into early July — check with the park information office in Le Bourg-d'Oisans before an early-season visit
- Arrive at the trailhead car park by 8:00 AM on weekends in July and August — the limited parking fills before 9:30 AM
- A packed lunch is essential; there are no food vendors on the trail and the Refuge du Lauvitel serves only hikers continuing overnight
When to visit
July to September offers the best conditions, with snow cleared from the upper trail and the lake fully thawed. Late July to early August sees peak sub-alpine wildflower bloom. Weekday visits in July and August reduce competition for the limited trailhead parking spaces.
