Brings you the best marine ecotourism experiences in Europe

The Quies are two large islands that lie off of Trevose Head, north of Newquay. They provide a great scuba diving site in waters from 15m to 20m deep, and if you stay in behind the islands, are sheltered from south westerly winds. The marine life is better than many of the other sites on the north coast with large brightly coloured dahlia and jewel anemones and a wide variety of fish. The diving site is rich with starfish, spider crabs, bryozoans (Bugula turbinata, similar to Christmas Tree worms), cup corals, dahlia anemones and sea squirts. The whole area is abundant with life.

On the north eastern side of the islands can be found the wreck of the Runswick, a steamship torpedoed by a German U Boat in April 1918. Most of the wreck is scattered, but two boilers can still be seen, one sitting upright on the seabed.
