Koh Man Nai is the heart of the Mun Islands and the closest island to the Rayong coast. The atmosphere is tranquil, surrounded by small coves such as Ao Ton Makham, Ao Hin Khod Ya, Ao Kong Kang, and Ao Na Ban, where shallow coral reefs can be found. What makes this island special is its role as the site of the Sea Turtle Conservation Project under the royal initiative of Her Majesty Queen Sirikit. Visitors can enjoy both the beauty of nature and learn about marine conservation. During low tide, the island reveals a “sandbar” that allows people to walk across the sea, creating a calm yet powerful natural scene.

 

This island is strictly for day visits only, with no overnight stays allowed. Rules are in place to preserve the fragile ecosystem. Visitors can join guided tours, listen to talks, see sea turtles at different life stages, and explore the island’s bays during designated times. Facilities are basic—restrooms and an information center—and there are no permanent shops, so it is recommended to bring your own drinking water and essentials, especially on sunny days.

 

Getting There Koh Man Nai is easily accessible from two main points: Laem Mae Phim (departing from Ao Makham Pom Pier) and Pak Nam Prasae. From Laem Mae Phim, the distance is about 5 kilometers, taking roughly 20–30 minutes by boat. From Pak Nam Prasae, the journey takes about an hour (9–10 km). The Ao Makham Pom Pier, about 3 kilometers from Laem Mae Phim, is the most popular departure point, offering private boat hire and day-trip tours often combined with Koh Man Klang or Koh Man Nok.

 

The best time to visit is during midday to late afternoon when the sandbar appears most clearly at low tide. Calm sea conditions are typical from late rainy season to early summer, ideal for families and older travelers. Useful items include sandals with good grip, a hat, UV sleeves, and a waterproof pouch for your phone. Most importantly, visitors are asked to protect the environment: avoid touching corals or sea creatures, do not litter, and respect the conservation zones.

 

The Laem Mae Phim area offers plenty of seafood restaurants and accommodations before and after your trip, such as Mae Phim Seafood and Krua Talay Seafood. The area around Ao Khai and Ao Makham Pom is a fishing community and the main pier for boat trips. Since Koh Man Nai has no accommodations or restaurants, it’s best to plan meals and transfers carefully so you can enjoy a full yet relaxed day and return to the pier before closing time.
