Difficult pass at first, especially in the heat. Easier after the first third. Be careful of the unlit tunnel 1 km from the summit. For added peace and quiet, the road leading up to the pass is closed to traffic from 4 p.m. to 6 p.m.

Culminating at 2,215 meters above sea level, it is the highest pass in the Pyrenees taken by a road. Overlooking the village of Saint-Lary Soulan, it offers a lovely panorama of the valley.

One of the most difficult passes in the Pyrenees and in France with really hard percentages that go on and on. When you leave the road to pla d'Adet you go up a small road of goats, it's really nice in the middle of sheep and cows. Be careful when crossing the tunnel near the summit because it is not lit and animals may be in the tunnel. The view is magnificent it is really a must. You just have to go down the road, so watch out for the cows because you pick up speed very quickly.

Very beautiful point of view on the surrounding peaks as well as on the peak of Bastan which awaits you. The night at the edge of the lake is very pleasant.

The best time for mountaineering in the Hautes-Pyrénées region, where Ens is located, is typically during the warmer months, from late spring through early autumn (roughly June to September). During this period, snow has usually melted from higher elevations, and weather conditions are generally more stable. However, always check local weather forecasts and trail conditions before heading out, as mountain weather can change rapidly.
Generally, permits are not required for hiking or mountaineering on established trails in the Hautes-Pyrénées. However, if you plan to access specific protected areas, engage in technical climbing, or stay overnight in certain refuges, it's always advisable to check with local authorities or national park offices for any specific regulations or booking requirements.
Specific parking information for each trailhead can vary. For routes starting from villages like Aulon, Cazaux-Fréchet-Anéran-Camors, or Vignec, you can typically find public parking areas within or near the village. It's recommended to check detailed route descriptions on komoot or local tourism information for precise parking locations and availability before your trip.
Public transport options directly to remote mountaineering trailheads in the Hautes-Pyrénées can be limited. While larger towns like Saint-Lary-Soulan (a nearby settlement) may have bus services, reaching specific starting points for routes like the Arbizon loop from Aulon or the Middle Bastan Lake – Upper Bastan Lake loop from Col de Portet often requires a car or a local taxi service. Planning your transport in advance is highly recommended.
Ens itself is a small village, but you'll find more amenities in nearby settlements. Towns like Vielle-Aure and Saint-Lary-Soulan offer a range of cafes, restaurants, and accommodation options, including hotels and gîtes, which are convenient bases for exploring the surrounding mountaineering routes.
Regulations regarding dogs on trails can vary, especially in national parks or protected natural areas. While many trails in the Pyrenees allow dogs, they are often required to be kept on a leash to protect wildlife and ensure the safety of other hikers. Always check specific signage at trailheads or consult local tourism offices for the most up-to-date information on dog policies for the particular route you plan to undertake.
