About this site
Coral Island, known locally as Koh Hae, is a reef dive site a 15-minute boat ride from Phuket, Thailand, suited to beginner divers and those completing early training dives.
The reef runs to a maximum depth of 10–12 metres (33–40 feet) at the bottom, with the shallowest point around 5 metres (15 feet), making the entire site accessible without deep-diving experience. Currents are minimal to non-existent, the site is sheltered and protected, and visibility is consistently clear. Water temperature sits at 26 °C. The best conditions fall between January and May and again in July. On the east side of the island lies an area known as Angelfish Garden, where angelfish move in numbers close to divers.
The reef holds a wide variety of marine life, including clownfish, angelfish, batfish, butterflyfish, fairy basslets, pufferfish, porcupinefish, triggerfish, eels, cuttlefish, decorator crabs, blacktip reef sharks, turtles, and Spanish dancers.

Access is by boat, with the crossing from Phuket taking around 15 minutes. The site's protected exposure, shallow depth, and absent current make it a first-choice site for beginner divers and introductory courses. No advanced certification or experience is required.
