Emerald Cave (Tham Morakot) Tours
1 Review

Emerald Cave (Tham Morakot) takes its name from the water’s vivid green color and is one of the most popular attractions in Thailand’s Trang islands. At first blush the cave looks like only a hole in a limestone cliff—but once you venture inside the dark entrance, a paradisiacal, sunny white beach appears.
The Basics
The tricky-to-access Emerald Cave is well worth the adventure. To reach the beautiful lagoon, you must join a guided tour that leads you on a swim through a 260-foot (80-meter) lit up by provided headlamps. Your destination is a large hall illuminated by sunlight shining through a small opening, and a sandbar surrounded by trees.
Most tours to Morakot Cave are included in the 4-island tour from Koh Lanta to Koh Chuak, Koh Muk, Koh Kradan, and Koh Ngai. These tours allow time for visitors to spend the day swimming, snorkeling, and kayaking in and around the four islands, discovering the underwater marine life and admiring the picturesque island scenery.
Things to Know Before You Go
- Emerald Cave is a must-visit for adventure seekers and nature lovers.
- Be sure to bring sunscreen, preferably one that is coral-reef friendly, and a towel.
- Do not attempt to visit the cave without a knowledgeable guide to direct you through the tunnel.
- Most tours offer snorkeling equipment, a buffet lunch, and light refreshments.
- Lifejackets are provided but be prepared—and fit enough—for a lengthy swim to access the cave.
How to Get There
The Emerald Cave is located on the western coast of Koh Muk, in the Trang province. You can access the cave only via one of the many tours offered on the Trang islands, and then by swimming through the narrow tunnel.
When to Get There
You can access the cave only during low tide, generally between 10am and 2pm, as the entrance passage is small and low. The best time to visit Koh Muk, and Thailand is general, is during the dry season (November to April).
Koh Muk
Branch out beyond the Emerald Cave and spend more time on Koh Muk. A 45-minute ferry ride from Khuan Tuang Ku Pier on the mainland, the small island has a handful of budget and mid-range accommodations (that generally operate only during the high season). Koh Muk’s beautiful beaches and great snorkeling spots offer spectacular ways to enjoy a relaxing holiday.
