Complete Guide to Hat Chao Mai National Park in Trang

About Hat Chao Mai National Park

Hat Chao Mai National Park sprawls across 230 square kilometres of the Trang coastline, and it still feels like a secret even in high season. Limestone karsts rise from milky-green water. Mangrove channels teem with mudskippers flicking across exposed roots. Beaches the colour of pale honey stretch for kilometres without a single sun lounger. The air carries salt and the faint sweetness of pandanus. At low tide you hear hermit crabs clicking across wet sand. The park owes its fame to its dugong population, which grazes on seagrass meadows around Libong Island inside the marine boundary. Sightings aren't guaranteed. Yet the possibility lures marine biologists and patient travellers alike. Beyond the dugongs, protected waters shelter sea turtles, reef fish in the shallows around Muk Island, and birdlife that justifies the mosquito bites on the mangrove boardwalks. What's refreshing is how little polish the place has received. The visitor centre is functional, not flashy. Signage fades in the sun. Boat operators haul wooden longtails onto the sand. You adjust to the park's pace. That's the whole point.

What to See & Do

Hat Chao Mai Beach

The park's headline beach runs for roughly five kilometres of fine, pale sand backed by casuarina trees that hiss in the afternoon wind. The water shelves gently, good for wading yet tame for swimming. At low tide rippled sand flats appear. You can stroll hundreds of metres. Sunsets stay quiet affairs. Thai families linger. A fisherman pushes his boat in. Woodsmoke drifts from someone's beach fire.

Tham Chao Mai Cave

Tucked into a limestone cliff at the park's western edge, this sea cave drips with mineral water from stalactites. Chambers open suddenly into daylight. Reach it by longtail boat at higher tides. Boatmen cut the engine inside so you hear water echoing against rock. Cave floods at very high tides. Timing matters.

Koh Muk and the Emerald Cave

Koh Muk sits within the park's marine zone and hosts Tham Morakot, the famous Emerald Cave. You swim through an 80-metre tunnel of pitch-black water. Then you emerge onto a hidden beach ringed by sheer limestone walls. The swim is short yet disorienting. Go early. By mid-morning day-trippers from Koh Lanta arrive. The cave can feel crowded.

Koh Kradan's Coral Shelves

Koh Kradan, also within park boundaries, has some of the clearest water on the Andaman side. Shallow coral shelves let you snorkel straight from the beach. Development stays minimal. A few low-key bungalow operations and not much else. That's why it keeps landing on lists of Thailand's underrated beaches.

Mangrove Boardwalk at Yong Star

A wooden walkway threads through the mangrove forest near the park headquarters. It's a vivid reminder of how much life these ecosystems hold. Watch mudskippers. Fiddler crabs wave oversized claws. Stay quiet and kingfishers flash between prop roots. Walk at low tide. Mudflats exposed. Smell of warm silt strongest then.

Practical Information

Opening Hours

The park is open daily from 8:30 AM to 4:30 PM at the main entrance and visitor centre. The beach itself stays accessible outside those hours. Boat tours to the islands typically depart between 9 AM and 10 AM. They return by mid-afternoon. Seas can pick up later in the day.

Tickets & Pricing

Entrance fees follow the standard Thai national park structure. Thai nationals pay far less than foreign visitors. There's an additional small fee for vehicles. Island day trips arranged through Pakmeng Pier sit mid-range by Thai standards. Prices usually include lunch and snorkelling gear. Multi-day passes are available if you plan to base yourself here.

Best Time to Visit

November through April is the dry season. Seas stay calm for island-hopping. That's why most people come. Trade-off: February and March can feel crowded around Emerald Cave. May to October brings monsoon rains. Boat operators sometimes suspend trips to outer islands. The mainland park itself stays accessible and is dramatically quieter.

Suggested Duration

A day trip from Trang town covers the mainland beach and one island. To do the park justice, meaning Muk, Kradan, and the mangroves at a sensible pace, you'll want two to three days. Base yourself at Pakmeng or on one of the islands themselves.

Getting There

Trang town sits about 45 kilometres inland. Pakmeng Pier is the main jumping-off point for the park's islands and beaches. From Trang, hire a songthaew or take a private taxi for a budget-friendly fare. The drive takes roughly an hour through rubber plantations and small fishing villages. Trang has its own airport with daily flights from Bangkok. This makes the park more accessible than a map might suggest. Longtail boats to Koh Muk and Koh Kradan leave from Pakmeng and the smaller Hat Yao Pier. Shared boats are considerably cheaper than chartering your own. You'll be on the operator's schedule.

Things to Do Nearby

Libong Island
Just outside the park's main cluster but within its marine boundary, Libong is the dugong-watching base. Local guides know the seagrass beds where the animals feed. They take you out in longtails at dawn when sightings are most likely. Pair it with Hat Chao Mai. It extends the marine ecosystem story the park is built around.
Pakmeng Beach
Sits immediately adjacent to the park boundary and is the launching point for most park activities. The beach itself has a row of seafood restaurants with plastic tables right on the sand. Order grilled squid and tom yum goong while boats glide in. Good for an evening meal after a day in the park.
Khao Chong Forest Park
Head inland from Trang town and you hit this pocket sized protected area. Waterfalls tumble, short jungle trails twist, giving you a sharp counterpoint to the coastal sweep of Hat Chao Mai. Half a day is plenty. It breaks the beach routine nicely.
Trang's Old Town and Dim Sum Quarter
Trang town wears its Sino-Thai heritage like a badge, nowhere clearer than at breakfast. Dim sum is serious business here. Around the railway station, old shophouses shelter coffee shops where locals fire up before sunrise. Pair this with a park visit. Most travellers stage out of Trang anyway.
Koh Sukorn
Push further south, beyond the park boundary, and Koh Sukorn appears. Water buffaloes wander rubber plantations. A handful of homestays dot the island. It feels lived-in, less curated. Worth the extra travel time if Muk and Kradan are already ticked off.

Tips & Advice

Book Emerald Cave for the first boat of the morning. By 10 AM snorkellers queue in the dark tunnel. That is exactly when you do not want company.
Bring cash. ATMs exist in Trang town and at Pakmeng. The islands themselves are largely cash-only. Bungalow operators sometimes add a premium for card payments when they accept them at all.
Sand flies patrol some of the quieter beaches, around dusk. Long sleeves help. Repellent with picaridin works better than DEET against them.
If dugongs are on your Libong wishlist, hire a guide tied to the local conservation project. Sightings rise. Boats keep a respectful distance from the animals.
Check the tide chart before plotting a Tham Chao Mai cave visit. Mid-tide is the sweet spot. Low tide strands boats. High tide floods the inner chambers.
