Discover Koh Samui's Coral Reefs

Snorkelling and Marine Adventures from Our Private Bay

The coral reefs of Koh Samui reveal an underwater world full of colours. Some of the island’s most captivating encounters lie beneath the surface of Banyan Tree Samui’s private bay. With direct access to the resort’s house reef and complimentary snorkelling equipment, guests are invited to a world of vibrant tropical marine life only moments from their villa. Beyond the shore, paddleboarding, sailing, and private excursions reveal the Gulf of Thailand from a more intimate perspective.


Discover Koh Samui’s aquatic wonders from the comfort of your private sanctuary, with this guide leading the way from the resort’s house reef to the open Gulf.

What Can You See While Snorkelling in Banyan Tree Samui’s Private Bay?

Banyan Tree Samui’s house reef rewards curious observation through a captivating underwater world. Copperband butterflyfish, trumpetfish, and parrotfish move among the corals, with giant clams below and the occasional blue-spotted stingray resting along the seabed.


The pleasure of exploring the Koh Samui coral reefs lies in the reef’s subtler activity. Simply observe fish slipping between corals, clams resting below, and colours shifting with the light as you drift over the marine life. These details make the Koh Samui coral reefs especially intriguing for families, underwater photographers, and first-time naturalists.


The guided house reef snorkelling experience introduces guests to this living habitat directly from the private bay. Sightings vary with the tide, visibility, and time of day, giving each swim its own character.

Which Marine Activities Can You Enjoy from the Private Bay?

Banyan Tree Samui’s private bay offers four non-motorised marine activities: snorkelling, kayaking, stand-up paddleboarding, and sailing. Complimentary equipment makes these Koh Samui beach activities easy to enjoy without leaving the resort.


  • Snorkelling: Enter from the private beach to explore the house reef. Equipment is available for adults and children.
  • Kayaking: Paddle along the bay’s sheltered coastline and view the resort’s hillside setting from the water.
  • Stand-up paddleboarding: Cross more mellow stretches of the bay at your own pace, with balance and sea conditions guiding the experience.
  • Sailing: Catch the coastal breeze aboard a small sailing craft for a contemplative journey across the bay.


All private-bay activities remain subject to daily weather and sea conditions, so make sure to consult the resort team for the safest and most rewarding time to enter the water.

How Can You Explore Coral Reefs Beyond Koh Samui?

The Koh Samui coral reefs are only the first chapter in your journey on this island. Aboard Sense of the Sea, Banyan Tree Samui’s private speedboat, guests are welcomed to partake in a fascinating course through the Gulf of Thailand towards neighbouring islands and more distant underwater landscapes.


Koh Tao is renowned for established snorkelling and diving sites, where colourful marine life thrives among the coral formations. Mu Ko Ang Thong National Marine Park unravels another side of the Gulf across its 42 limestone islands, further enriching the discovery of Koh Samui’s natural beauty. Depending on the itinerary, a visit may include snorkelling, sea kayaking, or a short climb to a panoramic viewpoint.


A private voyage from Koh Samui leaves room to linger at a peaceful anchorage or pause between discoveries. Routes depend on weather, visibility and sea conditions, with the crew being a reliable source of information before embarking on a new journey.

How Can Travellers Explore the Reef Responsibly?

A coral reef may appear serene, yet even brief contact can impact its fragile living structure. Travellers can protect the reef by keeping a respectful distance from coral, controlling their movements, and leaving every part of the habitat undisturbed.


  • Float above the reef: Maintain a horizontal position and keep fins clear of coral and the seabed.
  • Look without touching: Never stand on coral or collect shells, plants, and other natural objects.
  • Respect marine life: Do not chase, feed, or attempt to handle fish and other creatures.
  • Secure loose equipment: Prevent cameras, straps, and other devices from striking the reef.
  • Follow local guidance: Enter the water only when visibility, currents, and sea conditions are considered safe.

A Reef-Side Stay at Banyan Tree Samui

Beyond the water, Banyan Tree Samui’s strategic location keeps the connection between you and the Gulf of Thailand alive. Stay at an ocean view pool villa to have the full view of the coast from your private infinity pool and terrace - a natural choice for travellers who fancy a Samui resort with reef views.


After a morning in the bay, the resort’s thoughtful amenities await. Banyan Tree Spa Samui is home to ten treatment pavilions and The Rainforest hydrotherapy experience - a much-needed ritual after venturing around the bay. Later, the resort’s dining experiences present atmospheric spaces for guests to move between Thai cuisine at Saffron and private meals overlooking the bay. Each return to shore deepens the connection to the sea, transforming every moment into lasting memories.
