Depths range from 8 to 30 metres, allowing you to explore at different levels depending on conditions and experience. The site's rocky structure supports a typical cold-water marine environment. Expect to encounter wrasse, pollack, and other fish species common to UK waters. The terrain offers natural navigation challenges and photo opportunities for those interested in capturing UK seabed geology. Currents can be variable, so timing and local knowledge improve your dive. Lundy Island sits in the Bristol Channel between Devon and Wales.
