Zugarramurdi is the most famous, but Navarre has several caves we can explore.  In the Larraun valley, in the municipality of Astitz, a few minutes from Lekunberri, you will find the cave of Mendukilo, which reveals the depths of the Aralar mountain range. Its secrets, reserved for speleologists for years, are now open to the general public thanks to the work done to make it accessible. In the small Pyrenean village of Urdazubi/Urdax we can find the Ikaburu cave. It is a a grotto that originated some 14,000 years ago as a result of the erosion of the river Urtxuma that runs through it. A guided tour through its galleries- the only way to visit it – will open up a whole universe of stalactites and stalagmites as well as evoking the memories of people of legend: the soldiers and smugglers who used to occupy the caves in earlier times.
