Koh Haa Diving and Snorkeling Site (The Five Islands)

koh haa diving from koh lanta

Koh Haa Diving Site is for beginners and experienced divers, snorkelers and freedivers!

Once in Lanta, going scuba diving in Koh Haa is a must! The islands are six beautiful uninhabited limestone islands 16km west of Koh Lanta, inside the Koh Mu National Park. Discover Scuba diving has never been so easy like here, thanks to good visibility of the lagoon’s shallow water.

Said that they are the best place for beginners and snorkelers, they have as well more challenging and exciting areas for the experienced diver, like some deeper area in Koh Haa number 4,  Koh Haa Yai, or in Koh Haa Chimney.

Freediving as well cannot be missed in the cave or cathedral of Koh Haa.

Whale Sharks might be spotted all year round even though Koh Haa diving site is more famous for Tigertail Seahorse, Hawksbill Turtle, Bluspotted ray, Spotted Garden Eels, Pipefish, Gosthpipefish, Barracuda, Banded Sea Snake, Black Tip Reef Shark and the shy Guitar Shark. See most of these beauty simply by snorkeling in Koh Haa Lagoon with our experienced guides.

By the way, this spot will always surprise you, like for example when we found a whale skeleton on the sandy bottom… …and fun Fact! The word Koh Haa means five islands but actually they are six, so Welcome to Thailand! Click on the images below to discover more about this diving site and snorkeling area. The landscape itself is a unique postcard from the whole Krabi and Thailand spot. Keep in mind that Koh Haa, along with Hin Daeng and Hin Muang, are closed from 15th of May until 15th of October.

Koh Haa Chimney – Koh Haa 1 Neung

Koh Haa Chimney is famous for the tunnel system on the southwest corner.

The entrance of the Chimney

lies at 18 meters and opens up into a small chamber absolutely full of bronze cave sweepers, the exit hole above is at 5 meters. If you have exceptional buoyancy control you can enter another very narrow tunnel. It links up with a small cave, from which you can swim directly onto the reef again.

To the south of the Chimney

we find large limestone rock pinnacles that create a playground of channels and swim throughs. Huge pink and purple soft corals are also growing out of the sand everywhere below stunning drop off walls to 35 meters. This dive site is in pristine condition with big stuff in the blue and critters among the corals like Harlequin Shrimps, Ghost Pipefish and more.

Snorkeling

We recommend the east finger, turtles and nemo garden!

Koh Haa Lagoon Diving Site

Koh Haa Lagoon Diving place situated between the three central islands is a large protected lagoon with a small white powder sand beach. The lagoon itself is dotted with a variety of hard corals with shallow crystal clear water. This is the perfect place for your first diving experience and fantastic for snorkelling.

 Site Topography

The two smaller islands on the outside of the Koh Haa Lagoon we normally explore in one dive. The walls and ledges are covered with a mixture of sea fans and pink, blue and yellow soft corals. This scuba diving place is home to exotic reef dwellers like clown frogfish, Stonefish and in the sandy areas Seamoths and Guitar Shark. To the south and north of the central islands, deep water channels separate the other islands and offer a chance to see pelagic species as Whale Sharks.

Snorkeling

This is the easier and one of the best snorkeling place of all Koh Lanta Snorkeling trips: shallow clear water, turtles, baby sharks and a small white beach! perfect place for children as well!

Eagle Rays, Manta Rays and Whale Sharks have all been sighted at Koh Haa Lagoon dive site.

Koh Haa Yai: The Cave

The largest island in the Koh Haa group also called “ The Cathedral” or “The Cave”. This cave consists of two chambers. The largest of the chambers goes back into a second chamber with a large swim-through opening.
The main entrance to the cave lies at 14 meters and the opening goes all the way up to the surface. Inside the cave, divers can remove their regulators and breath the air inside.
The rock formations inside the cavern are amazing due to the light shinning in from underneath you from the entrance.
The East side of Koh Haa Yai is great for beginners and snorkelers with a very long shallow coral garden providing calm clear water.

The deepest part

A fantastic dive, possibly the best on Koh Haa. The reef drops to 30 meters with pinnacles on the west side to 40 meters and beyond. Colorful unique soft corals are abundant, with a complex and diverse marine eco system. And the biggest Groupers of all Ko Lanta dive sites! And maybe of the whole Thailand!

The Secret Garden of Haa Island – Koh Haa Six

As you have read above, Koh Haa means Five Islands but they are actually Six.

300 meters to the west of Koh Haa Yai here it is this small limestone rock island, the sixth island that we call “The Secret Garden”. It is possible to swim from the pinnacle to Yai island by following a ridge at 14 meters that ends on the north of the bigger island, but normally we start from the other side.

Most of the big boats might not take you to this place because of the hard mooring conditions but with our Speedboat we will be able to start our dive at the best corner to avoid strong current that might come ahead.

This dive site has the best coral of the whole Koh Haa area: delight your eyes on the reef to admire its healthy status with seahorses and other macro organism. But do not forget to look out in the blue for Barracuda, Travalleys, Turtles and, as we always said: finger crossed for the Whale Shark patrolling Koh Haa diving site.

Snorkeling

Swim around the pinnacle and in direction of Koh Haa Yai.
