Charter your very own luxury boat and explore the jungle-clad islands of the Angthong Marine National Park. With some of the best snorkelling and diving spots in the Gulf of Thailand, this paradise beneath the sea is best navigated by private boat. If you prefer to bask in the beauty of it all, cruising the Gulf in search of a remote beach or that perfect sunset has its own rewards.

Destinations & Highlights

    Angthong Marine National Park

    Angthong Marine National Park is a dreamy realm of turquoise waters and magical islands. Visit unspoiled beaches surrounded by dramatic limestone cliffs and lush vegetation, explore the caves and hidden lagoons, or go kayaking and snorkelling among the shallow coral gardens for a fun-filled and rewarding day trip.

  • View over lush tropical trees, mountains to white sand beach and ocean below
    Koh Tao and Koh Nang Yuan

    Koh Tao and Koh Nang Yuan are two small islands famed for their beautiful bays and crystal-clear waters. Discover their underwater marvels as you swim alongside vibrant fish and spectacular coral reefs.

  • Koh Phangan

    Koh Phangan has numerous white-sand beaches and secluded bays along its coastline, some of them reachable only by boat. Over three-quarters of the island is mountainous tropical forest, and much of the island is classified as a national park, which is why the island retains its natural, untamed beauty.

Full-Day Excursions


  • Angthong National Marine Park

Discover the unspoiled beauty of Thailand’s Angthong National Marine Park from the unique vantage point of our Four Seasons luxury yacht Minor Affair. Launched from Four Seasons Resort Koh Samui, your overnight private charter cruises the park’s rainforest-fringed islands, stopping along the way for snorkelling among the parrotfish, stingrays and colourful coral. Dive into the turquoise waters with your gear or simply don your snorkel and frolic as some of Thailand’s underwater treasures swim by.

Back on board, savour an al fresco lunch prepared by your own private Four Seasons chef on the spacious sundeck while surrounded by pristine scenery.

In the evening, sip tropical cocktails as you watch the sunset from a private beach, where you’ll be treated to a Four Seasons chef-prepared barbecue and bonfire, complete with fresh seafood and desserts. Afterwards, stargaze in seclusion on deck before retiring to one of the boat’s luxurious staterooms.

For a breathtaking sunrise, take an early-dawn excursion to Emerald Lake. If you prefer to sleep in, begin the day with an easy, late-morning hike through the jungle and take in the tropical scenery. Enjoy a picnic breakfast with a view, either on board or on the beach, followed by a few more hours cruising the marine park. Round off your unforgettable journey with more fine dining at sea with a specially prepared lunch by our chef before you return to the Resort. All meals are curated just for you by your private Four Seasons chef.
