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 Col du Tourmalet... a pass that was a real challenge for me! It climbs continuously for 20 km without any real respite... With the end getting a bit tougher, especially mentally!

Octave Lapize, the first to climb it on a bike during the tour. Check out the history, it's unmissable.

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.

These often follow old railway lines or canal paths, providing a safe and enjoyable experience away from cars.

Absolutely. The region is renowned for its high-altitude lakes.

Yes, the Lac de Gréziolles area is in close proximity to legendary Tour de France climbs. While the routes in this guide focus on no-traffic sections, you can easily integrate them with iconic passes like the Col du Tourmalet or Col d'Aspin for a more extensive and challenging touring experience.

For more extensive traffic-free cycling, consider exploring routes like the Vélosud, a 650km route along the Pyrenees that often uses quiet minor roads and dedicated cycle paths. This offers a more relaxed alternative to the high mountain passes. You can find more information on France Vélo Tourisme.
Beyond the stunning Lac de Gréziolles, the region offers dramatic granite ridges, lush mountain pastures, and diverse forests. Keep an eye out for the unique alpine flora and fauna. The Néouvielle National Nature Reserve, with its 70 lakes, is also a significant natural highlight in the broader area.
