Tuna Wreck
This small fishing-boat wreck was sunk by the Thai authorities in 2003 as an artificial reef, just past the south-east corner of Ko Ha (island 5), next to Hideaway Bay. It lies on its side on the sand at the bottom of the slope, with the top at about 28 m and the base near 40 m, and a buoy line leads down to it. Schools of batfish and clouds of glassfish hang around the hull, which is covered in soft corals and sea fans. The surrounding sand is home to partner gobies and razor wrasse, and blue-spotted rays rest nearby.
