About this site
This dive site features a dramatic underwater tunnel carved by waves, offering a thrilling swim-through experience. The rocky walls are covered in colorful anemones, sponges, and crustaceans. Expect strong currents that bring nutrient-rich waters, attracting schools of pollock, wrasse, and occasional seals. The entrance sits at 12 meters, sloping to 18-meter depths. Visibility is often excellent, revealing the site's rugged topography. Cold but rewarding, it's a highlight for UK divers.
