Similan Islands National Park

Located off the western coast of southern Thailand in the Andaman Sea, the Similan National Park is an archipelago of 11 stunningly beautiful islands, known for their white sandy beaches, crystal-clear waters, and breathtaking underwater scenery. Established in 1982, the park covers an area of approximately 140 square kilometers, encompassing both the islands and the surrounding marine areas. This tropical paradise is a must-visit destination for beach lovers, scuba divers, and wildlife enthusiasts alike.

The Similan Islands were named after the Malay word “sembilan,” which means “nine,” as the archipelago originally consisted of only nine islands. In 1998, two additional islands were added to the park, increasing the count to 11. The islands are numbered one to eleven, starting from the south, but they also have Thai names. The Similan National Park has been recognized as a UNESCO World Heritage Site, ensuring its protection and preservation for future generations.

The Similan National Park consists of 11 islands: Ko Huyong, Ko Payang, Ko Payan, Ko Miang, Ko Ha, Ko Payu, Ko Bon, Ko Tachai, Ko Similan, Ko Ba Ngu, and Ko Hin Pousar. The islands are divided into two main groups, with Ko Bon and Ko Tachai belonging to the northern group, and the other nine islands in the southern group.

The park is home to some of the most diverse and vibrant marine ecosystems in the world, with more than 500 species of hard and soft corals, over 200 species of fish, and various species of sea turtles, dolphins, and sharks. The islands are also a breeding ground for several bird species, including the Nicobar pigeon, white-bellied sea eagle, and the pied imperial pigeon.

Flora and Fauna

The Similan Islands are covered in lush tropical rainforests, with a mix of evergreen and deciduous vegetation. The islands’ plant life mainly consists of shrubs, bushes, and trees such as the banyan, bamboo, and rubber. The coastal areas are lined with mangroves and sea almond trees, which provide nesting sites for various bird species.

The islands are a haven for wildlife, with over 16 mammal species, including bats, flying lemurs, and squirrels. Reptiles, such as monitor lizards and geckos, can also be found on the islands. The marine life surrounding the Similan Islands is nothing short of spectacular. You may encounter whale sharks, manta rays, barracudas, and various species of sea turtles.

How to Get There

The Similan National Park is accessible only by boat from the mainland. The nearest pier is in Khao Lak, a popular tourist destination in Phang Nga province, approximately 70 kilometers north of Phuket. There are several options for getting to the park, including speedboats, dive boats, and liveaboard vessels. The boat journey from Khao Lak takes about 60 to 90 minutes, depending on the type of boat and sea conditions.

Where to Stay and Eat

There are no hotels or resorts on the Similan Islands, as overnight stays are restricted to maintain the park’s pristine environment. However, limited accommodation options are available on Ko Miang (Island 4), which is the park’s headquarters. Here you can find basic bungalows, as well as tents for rent. It’s important to book in advance, as availability is limited, and the park is closed during the monsoon season (from mid-May to mid-October).

Dining options within the park are limited to the park headquarters on Ko Miang, where a small canteen serves simple Thai dishes and snacks. Alternatively, if you’re visiting the islands on a day trip or as part of a liveaboard tour, meals are usually provided on board.

For a broader range of accommodations and dining options, visitors can stay in Khao Lak or other nearby towns on the mainland. These areas offer various types of accommodations, from budget guesthouses to luxury resorts, as well as a diverse selection of restaurants, cafes, and bars.
