Audio Guide of Mu Ko Ang Thong Marine National Park

The park is open year-round, approximately from 8:00 AM to 5:00 PM, although tours usually depart early in the morning. The main access is via organized boat tours from Ko Samui, which last about 6 to 8 hours; you can book through local agencies or online. For more details, visit the official website of Thailand's Department of National Parks: Department of National Parks.

The entrance fee is approximately 300 THB (around 8 to 10 USD) for foreign adults and 150 THB for children, but most tours from Ko Samui include this fee in the total price, which is around 1,500 to 2,500 THB per person. It is not free, but all-inclusive packages are the best option for saving money. Check updated prices at Thai National Parks.

A typical full-day tour lasts between 6 and 8 hours, including boat transfers, snorkeling, and short hikes. If you want to explore it more thoroughly, consider staying overnight on one of the islands, but the standard day trip is enough to enjoy the main attractions. Plan at least half a day if you go by speed ferry.

Established as a national park in 1980, Mu Ko Ang Thong protects an archipelago of 42 islands with rich marine biodiversity, mangroves, and unique rock formations, even inspiring the film The Beach. Its importance lies in the conservation of coral ecosystems and wildlife in the Gulf of Thailand. It is a key site for environmental education and sustainable tourism.

The dry season from December to April offers the best weather, with clear skies and calm waters ideal for snorkeling. Avoid the monsoon season from October to December because of storms; the ideal time of day is to depart early (around 8:00 AM) to avoid crowds and enjoy the natural light. Check forecasts on the official website before you go.

Access is limited due to rocky terrain, stairs, and uneven trails on the islands; there are no specific wheelchair facilities in most areas. It is recommended to check with the tour operator for adapted options, such as boats with ramps, but it is better suited to visitors with moderate mobility.

From Ko Samui, you can visit nearby Ko Pha-ngan, famous for its Full Moon parties, or the Na Muang waterfalls on the main island. Other options include snorkeling in Ko Tao or temples such as Wat Plai Laem on Ko Samui. These areas perfectly complement a route through the Gulf of Thailand; plan a combined itinerary to make the most of your trip.

Bring sunscreen, insect repellent, water shoes, and water; snorkeling is essential, so rent equipment if you do not bring your own. Book tours in advance during high season and choose operators with positive reviews to avoid overcrowded boats. Respect park rules, such as not touching corals, and bring a waterproof bag for your belongings.
