Things to Do in Trang in May

May still offers windows for island hopping in Trang's Andaman archipelago, though the season is winding down. Ko Muk's Tham Morakot, the Emerald Cave, is best reached early morning when the tide is low enough to swim through the sea-cave tunnel into the hidden lagoon beyond. May's lower visitor numbers mean you might have that cathedral of limestone and green water nearly to yourself. Ko Kradan's long east-facing beach, all white sand and shallow reef, is still accessible on calm days. The water is warm, around 29°C (84°F). Visibility varies but can reach 10 metres (33 feet) or more on mornings before the storms stir things up. The key is flexibility. Book with operators who offer next-day rescheduling in case of rough seas. Accept that one or two of your planned island days may become rain-day pivots.

This is the month when Trang's interior waterfalls stop being photogenic trickles and start thundering. Khao Pu-Khao Ya National Park, roughly 40 km (25 miles) northeast of Trang town, holds several multi-tier falls that peak from May onward as the monsoon feeds their catchments. The trails are shaded by dipterocarp forest so dense that even at midday the canopy filters the 34°C (93°F) heat into something tolerable. The sound of water crashing onto rock is audible long before you reach the falls themselves. The air smells of wet earth, rotting leaves, and something faintly sweet from the wild ginger that flowers along the lower paths. Go in the morning before the afternoon rains make the rock steps slippery. Wear shoes with serious grip. The pools at the base of the falls are swimmable and cold enough to make you gasp.

Kantang, the old port town about 25 km (15.5 miles) southwest of Trang city, sits where the Trang River meets the Andaman coast. Its Sino-Portuguese shophouses, crumbling in places but still gorgeous, line a waterfront that smells of salt and dried shrimp. Cycling here in May works because you ride early, from 6:30 to 10 AM, before the heat peaks and well before the afternoon rains. The roads between Kantang and the surrounding fishing villages are flat, paved, and nearly empty of traffic at dawn. You'll pass rubber plantations where the latex drips into coconut-shell cups tied to the trees, Muslim fishing communities with painted longboats beached on the mud, and roadside stalls selling roti with condensed milk that's still warm from the griddle. The humidity is high. Bring water. Expect to sweat. The coastal breeze along the estuary stretches takes the edge off.

Trang province sits on a karst limestone belt, and the cave systems here are extensive, cool, and largely unvisited compared to those in Krabi or Phang Nga. Le Khao Kob cave, carved into a freestanding limestone hill surrounded by rice paddies, is the most accessible. You walk through a passageway that opens into a roofless sinkhole where trees grow from the cave floor and light pours in from above. It's a surreal, almost cinematic space, and in May the vegetation inside is at its thickest green. The air inside any of Trang's caves drops to around 24°C (75°F), a genuine relief from the surface heat, and the stone walls are cool and slightly damp to the touch. Caves are the ideal afternoon-rain backup. When the sky opens up at 2 PM, you're underground and unbothered.

Trang's reputation as one of southern Thailand's great food towns isn't hype. The city's Chinese-Thai-Muslim culinary overlap produces things you won't find elsewhere in the country, and May's cooler evenings after the afternoon rain make the night market on Thanon Ratchadamnoen the best place to eat dinner. The air along the market arcade is thick with charcoal smoke, the sizzle of pork fat hitting hot grates, and the sweet-sour tang of Trang-style dim sum, which locals eat at all hours. Mu yang, the city's signature charcoal-grilled pork, has a caramelized crust and a smoky depth that comes from marinades that vary by family recipe but always involve coriander root and white pepper. Trang cake, a dense, sweet, slightly chewy confection sold in rounds, is the other local obsession. The market is best after 5 PM when the heat breaks and the stalls start firing up. By 7 PM the plastic stools are full of families. The noise level makes conversation a shouting match. Walk slowly. Eat at multiple stalls. Don't fill up on the first thing that smells good.

Ko Libong, the largest island in Trang's archipelago and accessible by longtail from Hat Yao pier, hosts one of Thailand's last viable dugong populations. These enormous, slow-moving marine mammals graze on the seagrass beds along the island's eastern shore, and May, despite being early monsoon season, is a reasonable window for sighting them because the seagrass is lush and the animals are feeding actively. Sightings happen from small boats in the early morning, usually between 6 and 9 AM, when the water is calmest and the dugongs surface to breathe every few minutes with a sound like a heavy sigh. The water is murky-green rather than postcard-blue in May, but that's the nutrient load that feeds the seagrass that feeds the dugongs. Ko Libong itself is quiet, Muslim, and largely uncommercialized. The beaches are not resort beaches. That's the appeal.
