Biescas

Highlight • Settlement

Biescas is one of the largest and most important municipalities in the Pyrenees. It has 19 population centers —in addition to Biescas itself—, but at least seven of them are uninhabited. It is considered the gateway to the Tena Valley and, in fact, remains of an ancient Roman road that communicated with it are still preserved.

Lanuza Reservoir

Highlight • Lake

In summer a festival is held in this reservoir, next to the town of Lanuza that gives it its name, on a stage that seems to float over the reservoir.

Col du Portalet

Highlight • Mountain Pass

From the south, the climb runs quite flat through the valley, in the course of which you pass two reservoirs, in which, depending on the water level, the ruins of the villages that had to be relocated can still be seen. In fact, there is more to see here than at the much better known Reschensee in the Alps.

Portalet Summit

Highlight • Other

The port is not particularly difficult on this side. There is a lot of traffic and there are no major gradients. The difficulty depends on the weather.

Nice view on lake at elevation of 1241m. Good place for quick stop near water on the way to top of Portalet.

Start of Puerto del Portalet

Highlight • Mountain Pass

At the beginning of the Port of Portalet you may find yourself somewhat tense due to the climb that awaits you. Enjoy the incredible views that this area offers you and prepare your legs to attack one of the most emblematic ports in the area and in the Pyrenees.
