If it's your first time in Trang, the first question is usually "should I do the islands or stay on the mainland?" The honest answer is you can comfortably do both, because Trang town sits only about an hour from the piers. The easiest approach is to split your days by theme — one day for an island tour, another for mainland nature and the old town — so you're not worn out and don't have to keep changing hotels. Most island tours leave from Pak Meng or Kuan Tung Ku pier, while mainland spots like Lay Khao Kob Cave and the old towns are scattered around the town and easy to reach by car.
Check Before You Plan
Trang's sea has seasonal island closures tied to the monsoon. As a rule, the Emerald Cave closes around September, and some islands close during the rough swells of August–September. If you're set on the sea, the window when the water is clear and boats run for sure is November to April. Confirm with your boat operator again before booking a hotel.
Islands and Clear Water
This is the main reason people come to Trang. The islands here have water clear enough to see coral from the surface, and they're still not as packed as the famous islands on the other side. Most can be done as a day trip by boat from the mainland — you don't have to stay overnight on an island to hit the highlights. A 3–4 island tour that includes the Emerald Cave is the most popular, best-value package for a first visit.
Emerald Cave, Koh Mook
The headline of Trang's sea. You swim through a dark cave about 80 meters long to reach a white-sand beach ringed by cliffs and open to the sky above. The water inside glows emerald green, hence the name. Most people go with a tour, since you need a guide to lead the swim.
Best BeachKoh Kradan
The finest white-sand beach in Trang, with clear blue-green water you can wade into along the whole stretch. There's shallow coral around the island for surface snorkeling, and plenty of people call it the prettiest island of the trip.
SnorkelingKoh Cheuk
The best coral-snorkeling stop on the tour. The island itself is tiny and you can't land, but the water around it has colorful soft coral and big schools of fish — a great place to pause and snorkel along the way.
NatureKoh Libong Dugong Spotting
Trang's largest island, home to Thailand's biggest seagrass beds, which are the dugongs' food source. Take a boat or climb the watchtower and you have a real chance of seeing dugongs. The sea-village pace is quiet, ideal for anyone who likes genuine nature.
Quiet IslandKoh Sukorn
A community-life island the crowds haven't reached, known for sweet watermelons and quiet beaches. It suits anyone who wants to slow down, cycle around the island, and lean into the atmosphere rather than the snorkeling.
Mainland BeachPak Meng & Chang Lang Beach
A crescent-shaped mainland beach running about 5 km, looking out at a karst shaped like a person lying on their back in the sea. It's a sunset spot and a departure pier for the islands — you can stroll it without ever boarding a boat.
Rough Island Tour Prices
A multi-island tour on a big boat (Emerald Cave–Koh Kradan–Koh Cheuk, plus Koh Waen) starts at around ฿850–1,000/person for Thais, including lunch, drinking water, fruit and a guide. A private longtail boat for 1–4 people runs around ฿3,900–4,000/boat. Prices shift with the season and group size, so check with the operator before booking.
Want more out of Trang? Book tours & activities
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.
Mainland Nature — Caves, Waterfalls, Mountains
Trang isn't only about the sea. The mainland has a cave you paddle through and a mountain range with waterfalls to stop at — a good fit for a second day after the islands, or for a day when the swell is up and boats aren't running. You can drive to all of these without needing a tour boat.
- Lay Khao Kob Cave (Huai Yot district) — a cave you ride a boat through along a stream running beneath the mountain. In some stretches the ceiling drops so low you have to lie flat in the boat — an experience that's hard to find elsewhere. The boat fee is charged per boat, and going early means fewer people.
- Banthat Range waterfalls — the mountains dividing Trang and Phatthalung, with several waterfalls and viewpoints. Good for light hiking and nature photos.
- Hat Chao Mai National Park — covering beaches, mangroves and several of Trang's islands, it's the launch area for many island tours, with campsites and nature trails.

On an evening when you're not out on a boat, Trang town is easy to wander. The old Sino-Portuguese shophouses are still fully intact, there's street art scattered down the lanes, and famous local eats like roast pork and dim sum are easy to find. The district of Kantang, a little further out, is an old port town with the southern Andaman line's terminus railway station — open since 1913 — worth a photo stop.
Trang Old Town Quarter
Sino-Portuguese shophouses and street art in the municipal area. Wander and shoot photos, then stop for roast pork, dim sum and an old-school tea house. Best walked in the cooler morning or evening hours.
HistoryKantang Old Town + Railway Station
An old port town on the Trang River, with street art and old buildings. The photo spot is Kantang Station, the classic yellow-and-brown terminus of the southern Andaman railway line.
How to Put It All Together
If your time is tight, stick to a simple rule: spend day one on the islands, then day two on the mainland and the town. That way you cover every theme without rushing. Here's a sample plan that actually works.
Island Tour — Emerald Cave + 3 Islands
Mainland Nature + Old Town
Getting Around Trang
Trang doesn't have the wide public transport of a big city, so if you want to hit several mainland spots, renting a car or a motorbike is by far the easiest. For the islands, use a boat tour with hotel pickup so you don't have to worry about the piers yourself. Straight up: if you're not driving, hopping between mainland spots gets a bit awkward.
