The Lareo reservoir is a small reservoir in a beautiful environment. The sheet of water creates a beautiful visual game with the dense forest that surrounds it.

This spectacular path through the beech forest is just a small sample of the incredible beauty of Aralar. The path runs pristine under the forest and, in some sections, looks out like a balcony from the cliffs.

This place is a must do if you like mountain bike and gravel. Easy to get lost at the end with dense fog, make sure you have your GPS charged. Also in autumn even is not that high can be very cold. tip for gravel: think about your tire pressure, rocks are a serious thing over there.
