Lac de Gaube is a classic Pyrenean destination, famous for its turquoise waters and the iconic backdrop of the Vignemale North Face.
This 8.2km round trip is a moderate mountain walk (Class 1) following the GR10 trail from the waterfalls of Pont d'Espagne.
The route is exceptionally accessible, with a seasonal gondola and chairlift option that reduces the hike to a brief 15-minute flat walk.
Located in the heart of the Parc National des Pyrénées, the trail is strictly regulated (no dogs) to protect local marmot and isard populations.
Ideal for families and first-time mountain visitors, the hike offers world-class alpine scenery with a relatively low 270m elevation gain.
Overview
Technical Summary
The ascent to Lac de Gaube, starting from the Pont d'Espagne near Cauterets, is one of the most accessible and celebrated mountain walks in the Parc National des Pyrénées. This 8.
The Vignemale Backdrop. The 'X-Factor' is the alignment of the 1,725m lake basin with the North Face of the Vignemale (3,298m). As hikers emerge from the pine forest, the horizon opens to reveal the massive triangular peak and its hanging glaciers perfectly centered across the water. This view is widely regarded as one of the most iconic landscapes in the Pyrenees range.
Hazard Assessment
Because the ascent follows a deep, rocky stream bed through thick pines, the path remains in deep shade. It is often covered in ice patches in May or October.
This is one of the 'Grands Sites' of the Pyrenees. In July and August, the path turns into a continuous line of hikers, destroying the tranquility of the valley.

Technical Profile
Vertical Ascent Profile
A steady, constant climb. Starting at roughly 1,454m at the Pont d'Espagne, the trail climbs up 271m over about 4km through the forest. It never flattens out until you reach the lake basin, but the gradient is remarkably forgiving and accessible.
Terrain Characteristics
Mountain hiking trail (Class 1) — well-marked alpine pathways through forest and valley terrain; no technical movement required.
The physical demand is defined by the 8.2km distance and local environmental conditions rather than vertical gain.

Matrix Profile
The HikeMetrics Global Matrix provides an objective, multi-dimensional assessment of technical difficulty, exposure risk, and environmental load.
Risk Summary
Professional evaluation of route mechanics and environmental stress factors. Recommended for participants within specified technical scope.
This profile uses the HikeMetrics v1.0 risk matrix, prioritizing environmental stress and movement complexity over simple elevation metrics.
Technical Specs
Access & Logistics
Regulations
Strict National Park regulations. Dogs are absolutely strictly restricted, even on a leash. No drones, no fires, no swimming.
Seasonality
Best from mid-May to October. In early summer, the water level is at its peak from glacial melt. The chairlift (Télésiège de Gaube) usually operates from June to September, providing an alternative to the 1.25-hour uphill walk.

Route Questions
Can I take the chairlift instead of walking?
Yes. During the summer, hikers can take a cable car from the car park, followed by a chairlift that drops you just 15 minutes of flat walking away from the lake. The purist's way, however, is walking up through the pines.
