Koh Kradan (Hat Chao Mai National Park)
Overview
เกาะกระดาน • Koh Kradan (Ko Kradan, RTGS)
Koh Kradan is a small tropical island in the Andaman Sea, approximately 10-13 kilometers off the coast of Trang Province in southern Thailand. Part of Hat Chao Mai National Park — established in 1981, designated a Ramsar wetland site in 2002, and recognized as an ASEAN Heritage Park — this 2.4 sq km island captured global attention in 2023 when it was named the world’s best beach by World Beach Guide (UK), a ranking recognized by CNN Travel.
What sets Koh Kradan apart is the exceptional shore snorkeling: a vast staghorn coral reef extends over 100 rai (~40 acres) along the east coast, accessible directly from the beach in waist-deep water. No boat required. The reef drops off approximately 200 meters from shore, creating one of Thailand’s most accessible underwater experiences. The southern bay of Ao Niang offers soft coral gardens with clownfish, best reached by a gentle forest trail.
The island is approximately 90% national park land with no permanent village, no roads, and no cars. Around 10 resort properties and a DNP ranger station comprise the only human presence. This remote, unspoiled character — combined with crystal-clear turquoise waters — earned Koh Kradan its global recognition.
For medical tourists, Koh Kradan offers an exceptional peaceful recovery environment with gentle beach activities and easy shore snorkeling suitable for those past initial recovery. However, the remote location means no medical facilities, no ATMs, and a minimum 1.5-2 hour evacuation to the nearest hospital — patients requiring immediate medical access should choose mainland destinations.
Park fees, operating hours, and ferry schedules are subject to change. Verify current information through the official DNP website or your transport operator before booking.
History & Significance
Hat Chao Mai National Park
- 1981: Established as a national park covering 231 sq km of coast, sea, and islands
- 2002: Designated a Ramsar wetland site (Site No. 1182) for critical seagrass and mangrove ecosystems
- ASEAN Heritage Park: Recognized for outstanding ecological significance
- BirdLife International IBA: Important Bird Area with 220+ species recorded
- First designated dugong conservation zone in Thailand: Herds of 20-30 dugongs documented in park waters
The 2023 Award
In 2023, World Beach Guide (UK) ranked Koh Kradan’s main beach #1 on its “Top 100 Beaches on Earth” list, catapulting the previously quiet island into international attention. Tourist numbers surged from approximately 300 per day to 2,000 per day. Local authorities and DNP are developing sustainability management plans to balance tourism with ecosystem protection.
Underwater Wedding Ceremony
Since 1996, Trang Province has hosted the annual Underwater Wedding Ceremony — a Valentine’s Day tradition held at 8 meters depth in front of Emerald Cave on nearby Koh Mook (not on Koh Kradan itself). The event holds a Guinness World Record for the Largest Underwater Wedding Ceremony. Since Thailand’s Marriage Equality Act, the ceremony is LGBTQ+ inclusive. Pre-wedding dive training is included for non-divers. Vow renewals are welcome.
Schedule (February 13-15 annually):
- Feb 13: Tuk-tuk parade, traditional Thai wedding ceremonies, photo shoots
- Feb 14: Underwater marriage registration at 1:00 PM, Rod Nam Sang ritual
- Feb 15: Visit Kantang district — traditional architecture and cuisine
The Name
The RTGS official romanization is “Ko Kradan.” “Koh Kradan” is the common tourist usage.
Natural Features & Ecology
Landscape & Geography
Koh Kradan is a narrow tropical island — approximately 4 km north-to-south and 300-800 meters east-to-west. The east coast features powder-white sand beaches with gentle entry into turquoise water. The west coast (Sunset Beach) is rugged and rocky. The forested interior rises to gentle hills of approximately 50 meters, with limestone karst formations throughout.
Marine Ecosystem
The warm Andaman waters around Koh Kradan support one of the healthiest reef systems in the Trang island group. The park’s monsoon closure period (June-September) allows reef recovery, contributing to exceptional marine biodiversity.
Coral Reef
The east coast reef is genuinely exceptional — 100+ rai (~40 acres) of living coral, dominated by extensive staghorn coral formations. The southern bay of Ao Niang features soft coral gardens at an average depth of approximately 5 meters. 23 coral species have been recorded in park waters.
Hard Corals: Staghorn coral (Acropora spp.) — dominant east coast species
Soft Corals: Gorgonians and soft coral species (Dendronephthya spp.) — dominant at Ao Niang

Snorkel Visibility: Approximately 6 meters at snorkeling depth during dry season.
Gear Rental: Available at resort properties on the island.
Scuba Diving
Koh Kradan is better known for snorkeling than diving, with local visibility limited to 6-8 meters. Dive operators offer trips to superior nearby sites.
Dive Sites
| Site | Depth | Features | Certification |
|---|---|---|---|
| San Chompuo (Pink Ridge) | 5-15m | Unusual coral, starfish, seahorses, lionfish, nudibranchs, moray eels. Shallow virgin reefs. | Open Water |

Dive Operators: Pro Scuba Diving Service (Koh Kradan), Trang Pro Dive (Koh Mook-based)
Diving Medical Advisory: Scuba diving is NOT recommended during any post-surgery recovery period. Diving carries risks including decompression sickness, barotrauma, and physical exertion that can compromise healing. Always complete diving medical questionnaires honestly and consult a dive physician if you have any health conditions.
Hiking
| Trail | Distance | Difficulty | Surface | Shade | Time |
|---|---|---|---|---|---|
| Kradan Beach to Sunset Beach Loop | ~2 km round trip | Easy | Forest trail, some sand | Good — forested interior | 30-45 min |
| East Coast Trail | ~2 km | Easy | Beach sand, forest path | Partial | 30-45 min |
| Kradan Beach to Ao Niang Beach | ~1.5 km | Easy | Forest trail, beach | Good through forest | 20-30 min |
| Koh Kradan Island South Loop | ~3 km | Easy-Moderate | Forest and beach | Mixed | 1-1.5 hours |
Guide Required: No Permits Required: No
Recovery Advisory: Walking trails are flat and well-shaded through forest sections, making them suitable for gentle recovery walks from Week 2+ after minor procedures. The South Loop is longer and may be tiring for those in early recovery. Walking on sand can be demanding for orthopedic recovery patients. Consult your doctor before any physical activity post-procedure.
Kayaking
Kayaks available for rent at some resorts. A good way to explore the coastline and reach Sunset Beach without walking the forest trail.
Swimming
Excellent — gentle beach entry, calm warm water in dry season. No strong currents along the main beach. The 200-meter waist-depth zone before the reef drop-off provides a safe, accessible swimming area.
Island Hopping
Longtail boats available for day trips to nearby islands:
| Destination | Travel Time | Highlights |
|---|---|---|
| Koh Mook — Emerald Cave (Tham Morakot) | 20 min by longtail | 80m swim-through cave to hidden lagoon beach. Best 10:00-14:00 at mid-tide for emerald light effect. |

Frequently Asked Questions
Is Koh Kradan safe to visit after medical procedures?
Beach relaxation on Koh Kradan is suitable 2+ weeks after minor procedures (dental, cosmetic) with doctor approval. The island is flat with gentle beach entry and warm, calm water during dry season — ideal for passive recovery. Shore snorkeling from the east coast is accessible without a boat in waist-deep water. However, there are NO medical facilities on the island — only a DNP ranger station with basic first aid. Emergency evacuation requires a 45-minute boat transfer plus 45-minute drive to the nearest hospital (1.5-2 hours total). Patients requiring immediate medical access should choose mainland destinations. Always consult your doctor before any outdoor activities post-procedure.
When is the best time to visit Koh Kradan?
The best time is December to March (dry season) with calm seas, clear skies, and excellent snorkeling visibility. November and April are also good with fewer tourists. The island effectively closes June to September — ferries and speedboats stop operating, most resorts close, and seas are rough and dangerous. February is particularly special with the annual Underwater Wedding Ceremony (February 13-15).
Can I snorkel directly from the beach?
Yes — this is Koh Kradan's standout feature. The east coast (Paradise Beach) has an extensive staghorn coral reef accessible directly from shore. The water remains waist-deep for approximately 200 meters before the reef drop-off, making it one of the most accessible snorkeling experiences in Thailand. Ao Niang (southern beach) has the best coral diversity with soft corals and clownfish. No boat required for excellent snorkeling. Gear can be rented at resort properties.
Is mobile phone signal available on Koh Kradan?
Limited. Some 4G coverage reaches from mainland towers but signal is patchy across the island. WiFi is available at resort properties only. This is critical for medical tourists — Koh Kradan has more limited connectivity than most Thai islands. Ensure someone on the mainland knows your itinerary and carry the park ranger station's phone number for emergencies.
What sunscreen can I use on Koh Kradan?
Only reef-safe mineral sunscreen (zinc oxide or titanium dioxide) is permitted. Chemical sunscreens containing oxybenzone, octinoxate, 4-methylbenzylidene camphor, or butylparaben are BANNED in all Thai national marine parks, with fines up to 100,000 THB (~$3,000 USD). Park staff may temporarily confiscate banned sunscreens at entry. Purchase reef-safe sunscreen at Boots or Watsons in Bangkok or Trang before arriving — selection on the island is nonexistent.
How do I get to Koh Kradan?
The most common route is flying to Trang Airport (TST) from Bangkok (1.5 hours, Thai AirAsia, Thai Lion Air, Nok Air), then a minivan to Pak Meng Pier (1-1.5 hours), then speedboat to Koh Kradan (30-40 minutes). Total travel time approximately 3-4 hours. There is no pier on Koh Kradan — ferries anchor offshore and passengers transfer to longtail boats to reach the beach.
Do I need to pay a national park fee?
Yes. The Hat Chao Mai National Park entry fee is 200 THB for foreign adults and 100 THB for foreign children. Thai nationals pay 40 THB adult and 20 THB child. Cash payment recommended — no e-ticket system was implemented at Hat Chao Mai as of late 2025. Fees are subject to change without notice.
Are there ATMs or shops on the island?
No ATMs on Koh Kradan. Bring sufficient cash for your entire stay. There is a small minimart with very limited basic supplies. All dining is resort-based — there are no independent restaurants. Stock up on essentials in Trang or at Pak Meng before boarding the boat.
