This dive site, Purrustarri, is characterized by numerous east-west facing rock slabs located in the lower parts of Mount Jaizkibel. Divers can explore these interesting geological formations alongside the intriguing remains of a shipwrecked fishing boat, which adds historical value and a focal point for navigation. The varied topography created by the slabs and the wreck provides diverse habitats and a compelling underwater landscape for exploration.
The marine life here is abundant and varied, particularly for macro enthusiasts. Divers can encounter numerous nudibranchs, octopus, cuttlefish, conger eels, spider crabs, scrapie, and lobsters. Larger marine animals include banks of pea, bogas, and bream, along with triggerfish and potentially sunfish (moons) in the area, offering a rich ecosystem to observe.
Purrustarri is an excellent dive site offering something for all levels, from beginners enjoying the shallower slab formations to more experienced divers exploring the wreck at 24 meters. The site's highlights include its unique topography, the accessible wreck, and its prolific macro life. While specific best times aren't provided, temperate seasons typically offer the best conditions for diving in Spain's coastal areas, with good visibility and warmer waters. It is also suitable for freedivers and snorkelers, especially in shallower areas of the slabs.
