Lac Blanc, the White Lake, sits at an altitude of 1,054 metres in the Alsace Vosges massif, set into the eastern slopes above the village of Orbey in the Haut-Rhin département of Grand Est, France. The lake owes its name to the pale grey granite bedrock visible beneath its remarkably clear water, which shifts between turquoise, slate blue and silver depending on cloud cover and angle of light. The shoreline is rocky and irregular, edged with blocks of grey granite and patches of coarse grey sand, without the developed beach infrastructure typical of lowland lakes. There is no supervised swimming zone and no lifeguard presence; wild swimming is possible in the shallower granite coves near the lakeside restaurant and parking area, particularly during the warmest weeks of July and August when surface water can reach 18–20°C. Water clarity is exceptional by Grand Est standards — visibility can exceed several metres in calm conditions — making it a favoured spot for wild swimming and photography among experienced swimmers willing to accept cool temperatures. The lake is managed primarily as a scenic and hiking destination. The lakeside restaurant occupies a terrace with direct views across the water to the Vosges crest and serves Alsatian specialities including choucroute and flambéed tarts, typically open from May through October. There are no sun loungers, no pedalos, and no formal swimming infrastructure; visitors find their own granite ledge or grassy patch near the shore. Fishing is permitted with a valid permit and the lake holds brown trout. Access is via the winding Route du Lac Blanc, a narrow single-track paved road ascending from Orbey over approximately 6 kilometres. Parking is available in a gravel lot at the summit, with a fee of approximately €3–5 in summer. No public transport reaches the lake. The GR5 long-distance trail and the Col du Calvaire circuit are accessible on foot from the parking area, offering above-treeline Vosges panoramas.

Tips for visiting
- There is no lifeguard — water stays around 18–20°C even in peak summer; enter gradually and avoid solo swims in rough weather.
- Arrive before 09:00 or after 16:00 in July–August; the parking lot fills quickly and the single-track approach road causes queues midday.
- Parking costs approximately €3–5 in summer; bring coins or a card as the machine may not accept large notes.
- Pack warm layers — at 1,054 m, temperatures drop sharply after 16:00 even in July.
- The GR5 trail from Le Bonhomme (approximately 2 hours uphill) is a scenic approach for fit hikers who want to avoid driving the mountain road.
When to visit
Late June through mid-September for tolerable swimming temperatures and an open restaurant. Early morning visits in July–August avoid parking congestion on the approach road. Snowshoeing access in winter depends on road closure conditions.
Accessibility
The parking area is gravel and flat, but the route from the car park to the water involves uneven granite rocks and natural terrain with no paved path or ramp. The site is not suitable for wheelchair users without assistance. The restaurant terrace is accessible from the car park with minimal steps.
