A Thailand holiday is not complete without a day trip to the Similan Islands from Khao Lak. The Similan Islands Marine National Park is famous for beautiful coral reefs, white sandy beaches and crystal-clear water.

The day begins when you arrive at Wow Andaman Pier. Once you have checked-in there is plenty of time to choose your snorkeling gear and enjoy a light breakfast before you meet your guide for the day. Before the boat departs, your guide will give you a short introduction to the Similans and give you a bit more detail about the plan for the day.

Soon it is time to board the speedboat. An early start means that you stay one step ahead of all the crowds. From Khao Lak to the Similan Islands by speedboat takes about 1 hour and 20 minutes.

The first stop of the day is on the island of Koh Miang. This island is the headquarters of the Mu Koh Similan National Park and has 2 of the best beaches for swimming and relaxing.

The first snorkeling spot of the day is just a short boat ride from the beach.

This is your chance to get up close and personal with a wide range of tropical marine life. Wild turtles and even the famous Nemo often make an appearance here. But make sure you save some energy! There is still another snorkeling stop to come.

Once everyone is back on the boat it is time to head for the second snorkel spot. Each bay in the Similan Islands has its own unique character and highlights. So, grab your mask and jump in!

The second beach stop of the day is at ‘Donald Duck Bay’ on Ko Simlan (Isl. 8). This is the biggest island on the Similan Islands map, and probably the most famous. Here the impressive granite rock formations line cascade down to the sea.

Lunch is served in the shade of the jungle, behind one of the most stunning beaches in Thailand. After lunch there is plenty of time to enjoy the beach or take a trek up to the ‘Sail Rock’ view point for a birds-eye view.

It is also possible to snorkel from the beach here for those who just can’t get enough.

Upon your return to the pier, your taxi will be waiting to take you back to your hotel in Khao Lak.

Simlan Islands National Park, Thailand

The Mu Koh Similan National Park is located about 65km (35 nautical miles) from Khao Lak. First established around 1982, the Similan Islands National Park covers and area of about 140km2 and include 11 different islands. To make navigation easier, the locals have numbered each island from South to North;

Isl. 1 – Koh Huyong
Isl. 2 – Koh Pa Yang
Isl. 3 – Koh Pa Yan

Isl. 4 – Koh Miang
Isl. 5 – Koh Ha
Isl. 6 – Koh Hok

Isl. 7 – Koh Payu
Isl. 8 – Koh Similan
Isl. 9 – Koh Ba Ngu

Isl. 10 – Koh Bon
Isl. 11 – Koh Tachai

The word ‘Similan’ comes from the Yawi dialect meaning 9. This refers to the main group of 9 islands which were first included in the national park. Koh Bon and Koh Tachai were included when the park was expanded in 1998.

Currently, only 7 of the islands are open to the public. Islands 1-3 have been set aside as a conservation area and permanently closed. Koh Tachai was briefly opened to the public, but was closed again in 2016 due to over popularity.

The rest of the park is open each year from the 15th of October until the 15th of May. There is now a cap of 3,850 visitor per day, so it is essential to book in advance. Especially at peak times.

The islands consist mainly of ancient granite rocks that were forced up by volcanic activity millions of years ago. Underwater the heavy white sand keeps the water crystal clear and perfect for snorkeling.

There is no ferry to the Similan Islands, so the only way to get to the Similan Islands is by speedboat or with a diving livaboard. There are also no hotels, shops or villages on the islands.

Some of South-East Asia’s most impressive marine life can be found around the Similan Islands. The quieter beaches on the islands make perfect nesting grounds, so snorkelers are often visited by both green turtles and hawksbill turtles. At certain times of the year it is also possible to see manta rays and whale sharks drifting past the islands. However, these gentle giants are mostly spotted when scuba diving.


When are the Similan Islands Open?
