Aitzulo is a huge cave which may easily be visited. The enormous passage was opened by erosion and is now just a cave ruin or natural bridge. Because of its size, it is easy to visit and has an almost flat floor. Light is not necessary, so many hikers include this cave into their hike. Probably because of the impressive view from the cave entrance.
