Islands Near Koh Samui: Top Excursions & Hidden Gems

Introduction: Koh Samui, the Perfect Gateway

Koh Samui is often celebrated as a tropical paradise in its own right—golden beaches, swaying palms, and a vibrant island lifestyle. Yet what makes Samui even more appealing is its location in the heart of the Gulf of Thailand, surrounded by some of the most beautiful islands in Southeast Asia. For visitors and expatriates alike, Samui isn’t just a destination—it’s the perfect launchpad for adventures to neighboring islands that offer everything from peaceful retreats to world-class diving.

Imagine stepping off the ferry to find untouched beaches, swimming with whale sharks, or paddling through emerald lagoons. Whether you’re here for a short visit or settling into expat life, island-hopping around Samui is an essential part of the experience.

1. Koh Phangan: Beyond the Full Moon Party

Most people know Koh Phangan for its legendary Full Moon Party, a monthly beach celebration that draws thousands of travelers. But beyond the neon lights and music, the island hides a softer, more soulful side that many expats and long-term visitors treasure.

Venture north and you’ll find hidden beaches like Bottle Beach and Haad Yuan, where turquoise waters lap quietly at the shore. Koh Phangan is also famous for its yoga and wellness retreats, with open-air studios overlooking the sea—perfect for those seeking balance and renewal. Inland, jungle trails lead to waterfalls like Phaeng and Than Sadet, offering refreshing escapes.

• Activities to try: snorkeling in secluded coves, café-hopping in Thong Sala, hiking to viewpoints.

• Travel tip: Ferries from Koh Samui to Koh Phangan run frequently, taking around 30 minutes to an hour depending on the service. Perfect for a day trip or a weekend retreat.

2. Koh Tao: Diver’s Paradise

If Koh Samui is the gateway, then Koh Tao is the crown jewel for divers. Nicknamed “Turtle Island,” it has earned a global reputation as one of the best places to learn scuba diving. Its clear waters, abundant coral reefs, and affordable dive schools attract everyone from beginners to advanced divers.

Underwater, you’ll find colorful coral gardens, schools of tropical fish, and even whale sharks for the lucky few. Popular sites include Chumphon Pinnacle and Shark Bay, each offering a unique glimpse of marine biodiversity.

Yet Koh Tao isn’t only about diving. The island is dotted with hiking trails and viewpoints like John-Suwan Viewpoint, where you can see panoramic vistas of twin bays. Kayaking, stand-up paddleboarding, and beachside relaxation round out the experience.

• Travel tip: Ferries from Koh Samui to Koh Tao usually take 1.5–2 hours. Many visitors stay at least 2–3 nights to fully enjoy the diving and relaxed vibe.

3. Ang Thong National Marine Park: A Natural Wonder

For pure natural beauty, Ang Thong National Marine Park is unmatched. This protected archipelago of 42 islands lies just northwest of Samui, a scattered paradise of limestone cliffs, hidden lagoons, and pristine beaches.

Day trips from Koh Samui bring you into this otherworldly setting where you can kayak between rocky outcrops, snorkel in crystal-clear waters, and hike to viewpoints that look out over emerald seas dotted with islands. One of the highlights is the Emerald Lagoon (Talay Nai), a saltwater lake hidden in the heart of an island.

Because Ang Thong is a national park, it remains largely untouched—development is minimal, and the focus is on preserving its ecosystem.

• Best way to visit: Join an organized tour or charter a private speedboat from Koh Samui. Trips usually last a full day, leaving early in the morning and returning by sunset.
