Impressive, both for its size and for being the best frame of Anboto.

Much more modest than the famous "Big Cave," but very interesting. It has a small bar, like a pub.

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.

Access to the interior is easy, but I can't say the same about the path leading up to here.

The most popular natural formation is the Eye of Aitzulo, near Oñati. It's a spectacular natural arch with a large eye-shaped opening overlooking the valley, offering impressive scenic views for hikers. Another highly appreciated spot is the View of Anboto from Udalatx Cave, which provides a stunning frame of the Anboto mountain.
Yes, the region is rich in prehistoric sites. While the original Ekain Cave, famous for its Magdalenian cave paintings, is closed for preservation, you can visit Ekainberri in Zestoa, an exact replica that offers guided tours and interactive activities. Other significant archaeological sites include Praileaitz Cave, known for Paleolithic art and ritual importance, and Ermittia Cave and Urteaga Cave, which have yielded valuable prehistoric findings. Information about these sites is often available through regional archaeological exhibits and visitor centers.
The caves in Alto Deba showcase a variety of geological features. The Eye of Aitzulo is a dramatic natural arch, not a deep cave system, but a striking rock formation. Other caves, like the Aitzorrotz Cave, are smaller cavities. The region's geology also supports the formation of sites with archaeological significance, often featuring unique rock formations that served as shelters or canvases for ancient art.
Yes, Ekainberri, the replica of Ekain Cave, is an excellent family-friendly option. It offers guided tours and interactive activities like making cave paintings or fire, providing an engaging way for all ages to learn about Paleolithic art and ancient life. While natural caves like the Eye of Aitzulo are popular for hiking, the accessibility for very young children might depend on the specific trail chosen.
The Alto Deba region offers numerous outdoor activities. You can find many mountain hikes, including challenging routes around the Aizkorri-Aratz Natural Park, which is home to some caves. There are also running trails and cycling routes that allow you to explore the natural beauty of the area surrounding these cave sites.
The Alto Deba region generally has a mild climate. For natural formations like the Eye of Aitzulo, which are often accessed via hiking trails, spring and autumn offer pleasant temperatures for outdoor activities. Summer can also be good, though it might be warmer. For indoor attractions like Ekainberri, visits are suitable year-round.
Access to original prehistoric caves like Ekain, Praileaitz, Ermittia, and Urteaga is generally restricted for conservation purposes, and permits are not typically available for public entry. However, replicas like Ekainberri are designed for public visits. For natural formations like the Eye of Aitzulo, no specific permit is usually required for access, as it's part of a public hiking area, but always check local regulations before your visit.
The replica site of Ekainberri is easily accessible and designed for visitors. For natural formations, while the Eye of Aitzulo is a popular hiking destination, its accessibility depends on the chosen route. Climbing from Araotz via the PR trail is described as very easy and short, while the path from the cave parking lot is much steeper. Always check trail difficulty before heading out.
Visitors particularly enjoy the impressive scenic views from natural formations like the Eye of Aitzulo, often describing it as a spectacular place with unbeatable landscape value. The unique perspective offered by the View of Anboto from Udalatx Cave is also highly appreciated. For the archaeological sites, the opportunity to connect with ancient history and art, especially through the immersive experience at Ekainberri, is a major draw.
While many significant caves are well-documented for their archaeological or natural importance, the region's rugged terrain means there are smaller, less-explored cavities. For instance, the Aitzorrotz Cave is a small cavity located just below the rock in front of the top/hermitage/castle, offering a more secluded experience. Another example is the Water Cave, described as more modest but interesting.
Many of the natural cave formations, particularly those popular with hikers like the Eye of Aitzulo, are often incorporated into circular hiking routes within the Aizkorri-Aratz Natural Park. These routes allow you to experience the cave as part of a broader scenic walk, offering diverse views and terrain.
