We made a short walk alongside the river near Jánovas: Rio Ara.

For the construction of a dam at Jánovas (which fortunately did not take place), large tunnels were made for work traffic in the past. Nature has taken it back!

The dead-end road is only 800 meters long but has now become a beautiful hiking trail for nature lovers.

The Rio Ara is one of the few free-flowing rivers in the Pyrenees.

Geological history is clearly recognizable even to non-geologists.

The short cul-de-sac is a must-see for geologists, biologists, bird watchers, flora enthusiasts, entomologists and of course also for amateur photographers.
