The Ordesa y Monte Perdido National Park is the oldest national park in Spain. In 1918 the Ordesa valley was designated as a national park. In 1982, the area expanded from 2,100 hectares to 15,608 hectares and was renamed "Parque Nacional de Ordesa y Monte Perdido. The park contains some huge canyons: Ordesa, Añisclo, Escuain and Pineta. Of a size that is not found anywhere else in Europe. The park has a height difference of 2,600 meters, from 750 meters in Añisclo to the 3,355 meters on Monte Perdido. This is the 3rd highest peak of the Spanish Pyrenees of which Ordesa is part. Since 1997 the park also falls under the UNESCO World Heritage.

Torla is the most important place and the gateway to the Valle de Ordesa. The village is situated at an altitude of 1032 m, on the left bank of the Ara river. It is surrounded by five peaks ranging from 2000 to 2848 m, covered with dense and green pine forests. The picturesque village has a small medieval center, cobbled streets and stone houses with slate roofs. The village owes its name to the tower (Torre) that had to defend the village against French invasions. This fort stood on the site of the current Romanesque church, upon entering the village on the large rock overlooking the valley and the road. It can be very busy here in July and August. There are a few restaurants, bars and a 16th century church with a beautiful Romanesque porch. Torla is also home to the Parque Nacional de Ordesa y Monte Perdido visitor center. There is a 20-minute film about the park. This is started in English on request. Furthermore, everything is in Spanish. There are also exhibitions about, among other things, the ibex. Open from 10 am - 2 pm and from 4 pm - 8 pm.
