Tucked just northwest of Koh Samui, Mu Ko Ang Thong National Marine Park is a stunning archipelago of 42 islands in the Gulf of Thailand. This marine sanctuary offers a perfect blend of rugged limestone cliffs, lush rainforests, hidden lagoons, and pristine beaches—making it one of the most captivating natural wonders in all of Southeast Asia.
Mu Ko Ang Thong, which translates to "Bowl of Gold," was established as a national park in 1980. Long before that, these islands were the secluded domains of sea gypsies and fishermen who revered the area for its abundant marine life and mystical charm. The park covers over 100 square kilometers, both land and sea, and is part of a larger conservation effort to protect Thailand's coastal ecosystems.
While the islands themselves are uninhabited, they hold deep cultural meaning for the Thai people. The surrounding communities on Koh Samui and Koh Phangan regard the area as sacred and deeply tied to local folklore. Some of the rock formations are believed to resemble mythical creatures, and Buddhist monks have been known to retreat here for meditation.
The landscapes within Mu Ko Ang Thong are nothing short of surreal. Towering limestone cliffs rise dramatically from emerald green waters. Hidden lagoons, like the Talay Nai Emerald Lake on Koh Mae Ko, are nestled in collapsed sinkholes and encircled by sheer cliffs. Hiking trails lead to breathtaking viewpoints offering panoramic vistas of the scattered islands.
Coral reefs teeming with life fringe the islands, and inland, dense jungles are home to monkeys, reptiles, and exotic birds. Each island has its own unique charm—some with powdery white sand beaches, others with mangrove forests and mysterious caves waiting to be explored.
Despite being a protected park, Mu Ko Ang Thong welcomes thousands of eco-tourists and adventurers every year. Its proximity to Koh Samui makes it an accessible day trip, while the opportunity to snorkel, kayak, hike, and dive in an untouched environment makes it irresistible.
The park gained additional fame after being featured in Alex Garland's novel "The Beach," which fictionalized a hidden utopia based on Ang Thong's magical setting.
There are no restaurants within the park itself, but day tours from Koh Samui usually include a delicious Thai lunch, often enjoyed picnic-style on a beach. If you're staying overnight or returning late, Koh Samui has numerous options:
Most visitors reach Mu Ko Ang Thong via speedboat or long-tail boat from Koh Samui, Koh Phangan, or even Koh Tao. The journey from Koh Samui takes about 45 minutes to an hour.
Tour operators on all three islands offer full-day packages that include boat transfers, guided tours, lunch, and park entrance fees. Private charters are also available for a more exclusive experience.
