On the climb to Cap d'Long, a detour to this lake is highly recommended. The climb and the scenery above are even more beautiful than the first.

Large, welcoming refuge. An invigorating, cool shower during our stay. Very good meal and a great atmosphere in the evening. The caretaker was attentive. Maps, guidebooks, books, and board games are available in the common room.

Large car park at the foot of the Tourmalet, there is a bike park here and there are opportunities to walk to the Néouveille lakes.

The succession of lakes in the opposite direction to what the majority of hikers do is a real eye-opener 🤩 Be careful, departure at 9am from the paid parking lot 🅿️ and we were far from being the first!

The region offers a mix of moderate and difficult mountaineering routes. For instance, the Lac d'Oredon – Pas du Gat loop is a moderate path offering scenic views, while the Gourg de Cap de Long – Pic de Campbieil loop is a demanding route requiring good fitness and alpine experience.
Route durations vary depending on difficulty and distance. For example, the difficult Gourg de Cap de Long – Pic de Campbieil loop, covering 13.8 km, typically takes around 6 hours and 54 minutes. A shorter, difficult route like the Néouvielle Peak loop (8.0 km) can be completed in about 5 hours.
Yes, many routes around Lac de Cap de Long are designed as loops. Popular options include the difficult Lac Blanc – Col de Madamète loop and the moderate Lacs des Aires loop.
The high-altitude environment means that late spring through early autumn (typically June to September) offers the most favorable conditions for mountaineering, with less snow and more stable weather. Always check local weather forecasts and conditions before heading out.
Mountaineering routes here offer stunning views of the rugged Néouvielle massif, numerous glacial lakes (around 70 in the reserve), and cascading waterfalls. You'll also encounter the impressive 100-meter-high dam of Lac de Cap de Long itself, and potentially other nearby lakes like Lac d'Oredon, Aubert, and Aumar.
While the guide focuses on mountaineering, the broader Néouvielle nature reserve offers scenic hiking trails around other nearby lakes like Lac d'Oredon, Aubert, and Aumar. These can provide a less strenuous experience for families looking to enjoy the high mountain environment.
The Néouvielle Nature Reserve has specific regulations regarding dogs to protect its pristine natural beauty and wildlife. It's essential to check the current rules and designated areas for dogs before your visit, as restrictions may apply.
Lac de Cap de Long is accessible via the D929, also known as the Route des Lacs. There are parking facilities available at the lake, which serves as a starting point for many mountaineering routes. Due to its popularity, especially during peak season, it's advisable to arrive early.
Access to Lac de Cap de Long, particularly the high-altitude D929 road, is primarily by private vehicle. Public transport options directly to the lake are limited or non-existent, especially outside of peak tourist seasons. It's best to plan for car access.
Generally, day hiking and mountaineering within the Néouvielle Nature Reserve do not require specific permits for access. However, it's always wise to check with local tourism offices or the reserve's official website for any updated regulations or specific requirements, especially for activities like bivouacking or large group expeditions.
The area is highly rated by the komoot community, with an average score of 4.8 stars. Reviewers often praise the dramatic high-altitude landscapes, the challenge of the routes, and the sense of unspoiled wilderness within the Néouvielle nature reserve.
While Lac de Cap de Long itself is a high-altitude, relatively remote location, there are typically refuges or small establishments open during the main season. For more extensive options for accommodation and restaurants, you would need to descend to nearby villages or towns in the Hautes-Pyrénées.
