Hin Daeng and Hin Muang

Hin Daeng

If Richelieu Rock is the best dive site in Northern Andaman, then Hin Daeng and Hin Muang, the striking twin outcrops alone in the open sea, are undoubtedly the best of Southern Andaman. Meaning ‘red rock’ in Thai, Hin Deang is covered with red soft corals, which makes the rock appear red. Only three small pinnacles are visible from the surface, but once underwater, the vast form of Hin Daeng stretches 30-40m down before reaching the sandy bottom. A long rocky wall consisting of soft corals, sea fans, and black coral stretches from the west to the south side of Hin Deang, reaching to the sandy bottom 40-45m underwater. The east and northeast side, on the other hand, is a reef slope with pinnacles and hard corals. The contour slopes down to the sand to depths of around 35-40m. Divers can also swim across the big channel on the north side of Hin Daeng, which leads to the west side. The hard coral reefs that top the pinnacles are good for snorkeling and are only 5-10m deep.

Hin Muang

The twin outcrops to the west of Hin Daeng are referred to as Hin Muang, which means “purple rock” in Thai. The outcrops are totally submerged and are covered with purple soft coral, hence the site name. The outcrops are long and narrow, reminiscent of loaves of French bread. There are several pinnacles, with drop-offs stretching down to the sandy bottom at 45 to 60m. The drop-offs around Hin Muang are rich with marine life and covered by soft corals, gorgonian sea fans and black corals. There are two mooring lines easily spotted at Hin Muang. One is at the west, near the channel where there’s a split in the rocks at 14m. The other is located at the pinnacle on the western side of the dive site, in a shallow, eight-metre deep area covered by anemones. To the east of this mooring buoy, there are a number of pinnacles at around 12 tm to 16m depth. Nearby is another mooring line, tied off at a depth of 22m, where the bottom is a mix of sand and rocks.
