Directly due south, a spectacular mountain drive takes you through the tunnel Aragnouet, to the Aragon region of Spain.

Here you can eat tapas and discover Monte Perdido, Mont Perdu, the lost mountain; the third highest of the Pyrénées at 3,352 m, and a UNESCO World Heritage site since 1997.

The area centred around the peak of Mont Perdu includes two of Europe's largest and deepest canyons, on the Spanish side, and three major cirque walls on the northern slopes, in French territory.

The site is also a pastoral landscape of meadows, lakes, caves and forests on mountain slopes, reflecting an agricultural way of life that was once widespread in Europe but now survives only in this part of the Pyrénées.

A breathtaking cable car ride from La Mongie ski resort, at 1,800m, takes you to the very top of the tallest of the French Pyrénées.

Founded in 1878, the Observatory is at 2,877m altitude. When construction began, the only transportation was by donkey! Discover the history and work of the Observatory in the Museum of Astronomy, or simply enjoy the unparalleled views of the Pyrénées. The 360° terrace offers uninterrupted views for 300km, taking in the entire chain of mountains.

Descend in the cable car, or for the more adventurous, by mountain bike or on skis, depending on the season.

Armchair mountaineers can look up to see the obervatory's white spheres, on the tallest peak, from most parts of the Lannemezan plateau.

Offers a variety of activities on the river, great for children.
