Ko Haa Neung is famous for ‘The Chimney’ cavern system – a tall, vertical chimney, often filled with small glassfish or sweeperfish.

The Chimney stars at around 5m and goes down to about 16m. Explore the arm that branches off the main chimney to the east, bringing you out into a beautiful shallow chamber with several large exits.

You can find banded sea snakes, lionfish, nudibranches, frogfish, harlequin shrimps, many other crustaceans and beautiful cowries. Look for large schools of snapper and barracuda – a little deeper, you can sometimes find Marble Rays.

Ko Haa Neung is the deepest of Ko Haa‘s dive sites and is very popular with experienced divers.

The dive site is home to ‘The Chimney’, an eerie underwater tunnel starting at 17 metres and rising all the way to a chamber at 5 metres, where a school of sweepers glint in the piercing rays of the sun.

The south side is made up of large, coral covered boulders with enough swim-throughs and macro delights to keep divers happy for hours.

The north and east of the island are reef slopes covered in Corals & Anemones, with beautiful schools of Snapper & a great chance to meet a local Hawksbill Turtle.

The south-west side of the island is a spectacular wall dive, with plenty of action in the blue & even a chance to see a Marble Ray or maybe even a Leopard Shark.

Ko Haa Neung is a varied and interesting dive site that is ideal for all kinds of underwater photography.
