Checklist of 7 heavenly islands in Rayong you must not miss this summer.

1. Koh Samet, the top landmark with everything on one island.

Koh Samet leads in popularity with its fine white sandy beaches and crystal-clear waters. It offers numerous bays for relaxation, complete with accommodations, cafes, restaurants, spas, and water activities. End your day at the sunset viewpoint at the island’s tip, guaranteed to capture plenty of great photos for social media.

2. Koh Mun Nai: An unseen eco-friendly island with a sandbar.

A paradise for eco travelers, visit the sea turtle conservation center to meet the adorable turtles and get your camera ready for the highlight—the sandbar stretching through sparkling clear waters during low tide.

3. Koh Mun Klang, a diver’s paradise.

This small island is full of charm, featuring short beaches alternating with rocky outcrops. If you enjoy natural, peaceful coral reef snorkeling, this island should be on your list.

4. Koh Mun Nok, an exclusive private island.

For those wanting to escape the bustle and relax on soft white sandy beaches, you can take a tour boat around the island to jump in for activities in peace, free from distractions.

5. Koh Thalu, the wonder of natural rock caves.

The island’s symbol is a large rock cave that the seawater flows through. Adventure seekers can hike up for panoramic sea views or enjoy snorkeling among vibrant coral reefs, both equally delightful.

6. Koh Kudi, a secret peaceful island with a hermit cave.

Hidden not far from Koh Samet, this very quiet island is perfect for escaping crowds. The highlight is the 'Hermit Cave' that appears during low tide—a small cave filled with colorful, unusual stones.

7. Koh Kham, an amazing sandbar connecting islands.

Surrounded by rocks and coral reefs, the highlight is the long sandbar that forms at low tide, linking Koh Kham with Koh Kruai, allowing you to stroll leisurely and enjoy the sea breeze.

This summer, if you want to escape the chaos and recharge without traveling far from Bangkok,Rayongis the answer. Tag your friends, tag your partner, and set off on your journey.
