This is an outing that families traditionally do on Sunday. People come here from Pau and Lourdes, and as far away as Pont d'Espagne.
Here you leave your car and you take a very well-indicated path, so there's no risk of getting lost or walking too far. The walk to the lake takes about one hour through the pines. If you are not a walker, take the cable car. You will then just have to climb a few hundred metres to reach this little rocky paradise tucked into the mountainside. Its name is a redundancy, as 'Gaube' in Gascon, means lake. In the distance, you can see the famous Pique Longue du Vignemale. For lunch, you can either dine in the restaurant or picnic on the grass.
You will then have time to observe the flora and fauna, and push on to the Refuge des Oulettes. Outdoor enthusiasts can cast a line and fish the river trout and Arctic charr that swarm in these waters.
