Lac de Capitellu

Lac de Capitello is a high-altitude lake tucked into the upper Restonica valley in the Haute-Corse region of Corsica, a short but demanding walk above the town of Corte. Sitting at 1,930 meters in a glacial cirque, it is generally regarded as the deepest natural freshwater lake on the island, plunging more than 40 meters below a surface that covers only around 0.055 square kilometers. Ringed by bare granite walls, the lake often stays partly frozen or snow-covered well into early summer.

Where is the lake located?

Capitello sits above its better-known neighbor, Lac de Melo, and together the two form one of the most popular lake pairings in Corsica. Both lie in the valley carved by the Restonica river, a tributary of the Tavignano, roughly 16 kilometers from Corte — the old Corsican capital and the natural base for exploring this part of the interior.

How do you get there?

Access is via the Restonica valley road, a narrow, scenic route that ends at the Frassetta parking area, where the walking trail begins. Because parking space is limited and traffic can be heavy in summer, a shuttle bus runs from Corte to Frassetta between early May and the end of September — using it avoids the hassle of hunting for a spot along the roadside.

How long does the hike take, and how hard is it?

The path is well marked but not casual. Reaching the lower Lac de Melo (1,711 m) and returning typically takes 6 to 7 hours. Pushing on to Capitello adds roughly another hour and a half each way. The final stretch is the toughest part of the route: the ground turns steep and rocky, with chains fixed to the rock in a few sections to help hikers scramble up safely. This is a full day out in the mountains, best suited to hikers who are reasonably fit and wearing proper footwear.

Why go beyond Lac de Melo?

Many visitors stop at Lac de Melo, which is already a scenic destination on its own. Those who continue on to Capitello are rewarded with a starker, wilder setting: a bare rock basin carved by glaciers, holding water with a striking turquoise tint. The contrast between the still lake and the jagged granite peaks surrounding it is often cited as one of the more dramatic mountain landscapes in Corsica.

When is the best time to go?

The hiking season for this route runs from May through October. Earlier in the year, snow can still linger around the lake itself, making the chain-assisted sections trickier to cross. Conditions are generally best from June to September, once the snow has fully cleared and the days are long enough to complete the full round trip without rushing.

Frequently asked questions

Can you drive directly to the lake? No. The road only reaches the Frassetta parking area in the Restonica valley; from there it's a multi-hour walk to reach Capitello.

Is the trail suitable for children? The section up to Lac de Melo is manageable for many families, but continuing to Capitello involves steep, chain-assisted sections that call for more strength and caution.

Can you swim in the lake? The water stays very cold for most of the year because of the altitude and snowmelt origin, though some visitors do take a brief dip during peak summer.

Do you need a guide? The trail is well marked and heavily used, so most hikers manage it on their own — but checking the weather forecast and wearing sturdy footwear is essential given the steep, rocky final approach.
