Known as La Caldera, in this place on the bed of the Ularra stream are these natural pools of water. In rainy seasons they fill up and become an ideal place to take a refreshing bath.

On dry ground it's quite slippery, so on wet ground... it's better to avoid it and go along the GR track.

It is part of the Plazaola greenway, and can be reached from both Lekunberri or Latasa and Irurtzun, on foot or by bike.

A place to go expressly, even if no more was done. It is super curious to see this hanging valley, the result of an ancient partial detachment of the upper cliff. Very very special.
