Koh Kradan is Thailand's most beautiful Trang island — white sand, turquoise bay, excellent house reef snorkeling, national park protection, and the world's only underwater Valentine's wedding. Our guide covers the top resorts and why Koh Kradan is the finest of the Trang archipelago.
Koh Kradan: Thailand's Most Beautiful Trang Island
Koh Kradan is a small island in the Trang archipelago — part of Hat Chao Mai National Park, accessible by speedboat from Pak Meng pier. It's consistently rated as one of Thailand's most beautiful islands: a single long beach of white sand facing a turquoise bay, with excellent snorkeling directly off the beach and limestone karst islands on the horizon. Development is minimal — a handful of resorts, no roads, no nightlife.
The island's most famous feature is the underwater wedding ceremony — Koh Kradan hosts Thailand's annual Valentine's Day underwater wedding, where couples exchange vows beneath the sea. This quirky tradition has made the island famous, but the real draw is simpler: one of Thailand's finest beaches in a national park setting.

Why Koh Kradan Stands Out
The Beach
Koh Kradan's main beach is one of Thailand's finest — a 1.5km arc of white sand with calm, clear water. The beach faces west, giving spectacular sunset views over the Andaman Sea. Unlike many Thai beaches that get crowded with day-trippers, Koh Kradan's national park status and remote location keep visitor numbers low.
House Reef Snorkeling
The reef directly off the beach has excellent coral and abundant marine life — sea turtles, reef fish, and occasional reef sharks. Visibility averages 15–20m during the dry season. The snorkeling is accessible directly from the beach without a boat.
Proximity to Koh Mook & Koh Ngai
Koh Kradan is part of the Trang island cluster — Koh Mook (Emerald Cave) is 30 minutes by longtail, and Koh Ngai is 45 minutes. Day trips between the islands are easy to arrange, making Koh Kradan a good base for exploring the entire Trang archipelago.
Getting to Koh Kradan
- From Pak Meng pier: 1-hour speedboat. Pak Meng is 40km from Trang town, which has an airport with connections to Bangkok (1 hour).
- From Koh Lanta: 1.5-hour speedboat (seasonal, November–April).
- From Koh Ngai: 45-minute longtail.
Important : Koh Kradan closes approximately May–October due to monsoon season. Visit November–April only.
Best Time to Visit
- November–April: Dry season, calm seas, best snorkeling. Peak season December–March.
- May–October: Monsoon season — island closed.
Frequently Asked Questions
Is Koh Kradan better than Koh Ngai?
Both are excellent Trang islands with similar character. Koh Kradan has a slightly longer beach and is marginally more developed (more resort options). Koh Ngai has better house reef snorkeling and is slightly quieter. Both are far superior to more crowded Andaman islands for travelers who want quiet and good snorkeling.
What is the underwater wedding on Koh Kradan?
Thailand's Tourism Authority organises an annual Valentine's Day underwater wedding ceremony on Koh Kradan — couples in scuba gear exchange vows beneath the sea, officiated by a diver-officiant. It's a quirky tradition that has run since 1996 and attracts couples from around the world. Participation requires advance registration with the Tourism Authority of Thailand.
Is there nightlife on Koh Kradan?
None — Koh Kradan has no bars, no nightlife, and no entertainment beyond resort dining. This is entirely the point. If you want nightlife, choose Koh Lanta or Koh Phi Phi.
