Arlegileze

Access is from the water tank in Irurtzun; after passing through a metal gate, you go up along a path that crosses a pasture. You reach a fork where a post signals two options, and you must follow the option (vulture balcony). Once at that balcony and next to a small water pool (depending on the time of year it is usually dry), you look toward the summit of Mount Erga; after spotting it, you move your gaze to the left until you see a very striking scree slope. After climbing the uncomfortable and grueling scree slope in a straight line, you arrive in front of a huge rock wall, at whose base is the cueva de Arlegileze.
