If you climb from Araotz, follow the PR, and the climb is very easy and short. From the cave parking lot, it's much steeper and zigzags. About 2.5 or 3 km with a lot of elevation gain.

This time I went about 100-200 meters, until I reached some stairs with something resembling railings. I didn't go any further because I was alone, without signal, and I was afraid of going any further.

Located above a cave, this hermitage is next to the river and the old road that connected with the Cantabrian coast and Duranguesado. It is located next to a climbing area.

The caves around Aramaio are unique due to their blend of geological wonders, historical significance, and deep ties to Basque mythology. You'll find everything from small historical refuges like Apaiz Koba to extensive systems within the Urkiola Natural Park, some associated with the goddess Mari.
Visitors are often impressed by the spectacular landscape value, especially at places like Eye of Aitzulo, which offers extraordinary views from its interior. The monumental entrances of caves like Baltzola and the challenging natural formations, such as Abaro Tunnel, also leave a lasting impression.
Yes, several caves hold historical and mythological significance. Apaiz Koba in Aramaio served as a refuge for a Carlist priest during the Carlist Wars. Within Urkiola Natural Park, caves on Mount Anboto are linked to Mari, the goddess of the Earth in Basque mythology. Supelegor Cave in Gorbeia Natural Park also has strong mythological ties to Mari and evidence of Neanderthal presence.
The region's karstic relief means many caves feature impressive formations. Eye of Aitzulo is a natural monument known for its unique 'eye' formation. Baltzola Cave boasts a complex system of galleries, rooms, and sinkholes. Supelegor Cave is celebrated for its gaping entrance and a unique ray of light that penetrates deep inside.
While many caves require caution, the initial 250 meters of Los Goros Caves in Sierra de Badaia are generally walkable and considered family-friendly, offering a beautiful route through nature. For deeper exploration, proper caving equipment and a guide are recommended.
The difficulty varies significantly. Some caves, like the initial sections of Mairulegorreta, have easy access. Others, such as Abaro Tunnel and Baltzola Caves, are considered challenging and may require flashlights or even caving equipment for deeper sections. Apaiz Koba is difficult to access due to its narrow opening.
For basic exploration of some caves, a flashlight is often recommended or almost mandatory, as noted for Abaro Tunnel. For deeper or more challenging sections, such as in Mairulegorreta or Los Goros Caves, specialized caving equipment and potentially a guide are necessary.
Yes, for those seeking a more intimate experience, Apaiz Koba is a small, less-traveled cavity known more for its historical anecdote than its size, offering a glimpse into local history away from larger crowds. The journey to Supelegor Cave through the Itxina massif also provides a sense of adventure and solitude.
The region's caves can be visited year-round, but conditions vary. After rain or snow, Los Goros Caves are particularly impressive due to enhanced water features. Always check weather conditions, as some caves may involve getting your feet wet during the rainy season, as noted for Abaro Tunnel.

You can find numerous running trails, such as those around Urkiola Pass, or explore gravel biking routes like the Ullibarri-Gamboa Reservoir loop.
