One of the most iconic and rewarding walks in the French Pyrenees, starting from the spectacular Pont d'Espagne waterfall confluence and climbing through forest and open terrain to the stunning Lac de Gaube (1,730 m), which reflects the snow-capped mass of Vignemale (3,298 m) in its still waters. A télésiège (chairlift) from Pont d'Espagne can shorten the climb.
The walk to Lac de Gaube from Pont d'Espagne is one of the most celebrated and scenic routes in the Hautes-Pyrénées department of Occitanie. The trailhead begins at the Pont d'Espagne waterfall complex near Cauterets, reached by car along the D920 from Cauterets town (7 km); a paying car park operates in summer (approximately €6 per day), and a shuttle bus runs from Cauterets centre in season. A télésiège (chairlift) operates seasonally from Pont d'Espagne, reducing the climb by approximately 200 metres for those seeking a gentler ascent. The walk covers 8.2 kilometres round trip with 375 metres of elevation gain, typically completed in 3.5 to 4.5 hours. The lower section climbs through mixed conifer forest on a wide stone-paved mule track, passing close to the spectacular confluence of the Gave de Gaube and Gave de Cauterets — the famous Pont d'Espagne itself — where two mountain torrents merge in a cascade of white water. Above the chairlift station, the terrain opens into the Parc National des Pyrénées proper, with views expanding across alpine meadows scattered with wildflowers throughout summer. Marmots are regularly spotted sunning on boulders along the upper section, and griffon and Egyptian vultures patrol the ridge walls overhead. Lac de Gaube sits at 1,730 metres, a deep glacially-carved lake whose still, dark-green waters reflect the north face of Vignemale (3,298 m), the highest peak on the French–Spanish frontier and one of the most iconic Pyrenean panoramas. A seasonal mountain refuge, the Chalet-Hôtel du Lac de Gaube, operates throughout summer, offering drinks and light meals; walkers can swim in the lake, though water temperatures remain cold even in August. The path surface is a mix of paved mule track, compacted rock, and earthen trail; shade is limited above the treeline. No permit is required for day use. Wild camping is prohibited within the national park boundary. Isard (Pyrenean chamois) are occasionally visible on the rocky slopes surrounding the lake, and the permanently glaciated Vignemale face forms a dramatic backdrop at the water's edge.

Tips for visiting
- Start from Cauterets before 08:30 to reach the lake ahead of peak crowds, which build rapidly from 10:00 onwards in July and August.
- The seasonal télésiège from Pont d'Espagne cuts around 200 m of ascent; confirm operating dates with the Cauterets tourist office before visiting.
- Bring a warm layer — the lake sits in a north-facing cirque and temperatures drop noticeably at the lakeshore even on warm valley days.
- Swimming at Lac de Gaube is possible from mid-July; water stays cold (around 12–14°C) and the lake is deep, making it suitable for confident swimmers only.
- Marmots, chamois, and vultures are most reliably spotted in the early morning before trail traffic increases from mid-morning.
When to visit
Late June to mid-September offers the most reliable snow-free conditions; July and August are the warmest months for swimming at the lake, though crowds are at their peak. Mornings are significantly quieter than afternoons throughout the summer season.
Accessibility
The lower 2 kilometres of the trail from Pont d'Espagne follow a broad paved mule track passable with a robust all-terrain pushchair in dry conditions. Above the chairlift station the surface becomes rougher rocky path, which is not wheelchair-accessible. The seasonal télésiège offers partial assistance for those unable to manage the full ascent on foot.
