How does fishing in Trat compare to Pattaya?

Trat is quieter in every sense — fewer boats, fewer tourists, less commercial pressure on the water. The charter scene is smaller and less organised, but inshore fishing quality is comparable and the setting is considerably more pleasant. You'll work harder to arrange a boat but the payoff is uncrowded water.

What species can I target around Koh Chang?

Inshore species include mangrove jack, barramundi in the estuaries, snapper and grouper on reef structures, and queenfish and giant trevally in the passes between islands. Trolling between Koh Chang and Koh Kood opens up wahoo, Spanish mackerel, and the occasional sailfish in season.

Is Koh Chang good for snorkelling as well as fishing?

Yes. The island has decent coral on the south and west sides, and combining a light fishing charter with snorkelling stops is a popular option. The water visibility in the dry season (November–April) is the best it gets on the Eastern Gulf.

Can I fish near the Cambodian border?

The maritime boundary in this area means fishing boats need to be aware of their position. Responsible operators know the limits. Do not fish independently close to the maritime boundary without a licensed operator who knows the waters.

When is the best time to fish around Koh Chang?

November through April is the dry season on the Eastern Gulf — this is the optimal fishing and travel window. May through October brings the southwest monsoon, which makes the west coast of Koh Chang rough; the east coast remains calmer. July and August are the roughest months and some charter operators cease operations.

Are there kayak fishing options around Trat's mangroves?

Yes. The mangrove networks around the Trat estuary and the smaller islands east of Koh Chang are well-suited to kayak fishing. Several operators in Koh Chang offer mangrove kayak tours that can be adapted for light fishing. This is some of the most atmospheric fishing available on the Eastern Gulf coast.

How do I get to Koh Chang from Bangkok?

Drive or take a bus to Laem Ngop ferry pier (approximately 5–6 hours from Bangkok), then ferry to Koh Chang (30–45 minutes). Alternatively, fly to Trat Airport and take ground transport to the ferry — flight time is about an hour.

Trat and Koh Chang: The Eastern Gulf's Quiet Corner

Koh Chang means Elephant Island, and the name suits it — it's large, heavily forested, and moves at its own pace. While Koh Samui built luxury resorts and Phuket became a city-sized tourism machine, Koh Chang remained somewhere you went to genuinely switch off. The western coast got a modest strip of beach bars and dive shops; the eastern coast stayed almost entirely local.

For anglers, this trajectory has produced something increasingly rare on the Thai coast: water that isn't being systematically overfished by a commercial charter fleet. The boats that work these waters are few, the locals who fish here are serious, and the pressure on the reefs and estuaries is a fraction of what you'd find around Pattaya or Ko Samui.

That's the pitch for Trat province and Koh Chang — not the biggest catches, not the most organised charter scene, but genuinely quiet water in a genuinely beautiful setting with enough species variety to keep most anglers happy for several days.

Regional Overview

Trat province occupies the southeastern corner of the Gulf of Thailand, sharing a land border with Cambodia's Koh Kong province and a maritime boundary that has occasionally been the subject of bilateral discussion. The provincial capital, Trat city, is a modest market town with good transport connections and a functional guesthouse scene.

The province's coastline is an archipelago geography — dozens of islands scattered across the shallow Gulf shelf, separated by channels that concentrate current and create productive fishing zones. The largest island, Koh Chang, dominates the seascape. Koh Kood, further south, is even less developed. Between and around them, the waters are extraordinarily calm in the dry season — almost lagoon-like in texture.

The mainland coast is characterised by mangrove estuaries, particularly around the Trat River mouth and the waterways north of Laem Ngop. These brackish, tannin-stained channels are the hunting ground for barramundi, mangrove jack, and snakehead — different fishing entirely from the offshore reef work, but compelling in its own right.

"Koh Chang's fishing is like the island itself — understated, unhurried, and better than you expect once you stop comparing it to somewhere else."

Species

Mangrove and Estuary Species

The mangrove channels around Trat are among the more productive barramundi environments on the Eastern Gulf. Barramundi here aren't the giants of Northern Australia's river systems, but fish in the 2–5kg range are achievable and they fight hard in confined water. They take both live bait worked near structure and surface lures — particularly poppers and walk-the-dog style plugs worked parallel to the mangrove root systems in low light.

Mangrove jack share the same habitat and are arguably more aggressive. They're ambush predators that hold tight to structure and bolt for cover the instant they're hooked, which means you need heavier leader than you think and you need to turn them immediately. A 40lb fluorocarbon trace is not excessive.

Snakehead — primarily giant snakehead in this coastal mangrove system — will take surface lures and live frogs worked close to the mangrove margins. They're not easy to find, but a patient, methodical approach to likely-looking bays and channels can produce encounters that will occupy your fishing memory for years. See our giant snakehead species profile for approach detail.

Reef Species

The inshore reefs around Koh Chang — particularly the south-facing structures off the island's southern tip and the reefs between Koh Chang and Koh Kood — hold a typical tropical reef assemblage: various snapper species, coral grouper, yellowtail fusilier, and wrasse. These are primarily bottom fishing targets, worked on flasher rigs or with live bait on standard paternoster rigs.

The passes and channels between islands concentrate current and create ambush zones for pelagic species. Queenfish are a reliable target in these locations — they take jigs, poppers, and flashy metals and provide excellent light-tackle sport. Giant trevally inhabit the same passes in smaller numbers; a 3–8kg GT on light jigging gear in clear turquoise water is the kind of fishing that Trat does quietly and without fanfare.

Offshore Targets

Moving further offshore — beyond the island chain and into deeper Gulf water — the trolling scene opens up. Spanish mackerel are the primary target from November through February; wahoo and dogtooth tuna appear in smaller numbers. The occasional sailfish encounter is on record in this area during the November–January peak season.

This offshore fishing requires a capable boat and good local knowledge of the productive tracks; smaller charter vessels in Trat are not always set up for full offshore work. Discuss capability with any operator before booking.

For mangrove kayak fishing specifically, Koh Chang has several operators who run guided kayak tours that can be modified for light fishing. This is an excellent option for anglers who want to combine fishing with the immersive experience of paddling through the root systems. See our mangrove kayak fishing guide for preparation tips.

The Charter Scene

Trat's charter scene is smaller and less commercialised than Pattaya's or Koh Samui's. There are boats available — longtails for the mangroves, small fibreglass speedboats for inshore reef work, and a handful of larger vessels capable of offshore trolling — but they're not always easy to find through traditional booking channels.

The most reliable approach is to arrive in Koh Chang or at Laem Ngop pier and ask directly at the fishing piers and boat yards. Local fishermen are often willing to take recreational anglers on half-day or full-day trips, providing an authentic shared-boat experience rather than a formal charter. Language can be a barrier; a translation app and patience go a long way.

For kayak fishing and mangrove exploration, dedicated eco-tour operators in Koh Chang's beach areas are a more structured option and can be booked in advance online.

See our Pattaya charter operators overview for comparison with the larger Gulf charter scene to the northwest.

When to Come

November to April is the optimal window. The Gulf is calm, visibility is excellent, and all fishing types are at their best. December and January are peak season for the island generally — accommodation books out and prices rise — but the fishing is at its most productive.

May to October brings the southwest monsoon. The west coast of Koh Chang takes the brunt — Hat Sai Khao and Lonely Beach can see rough seas and difficult beach conditions. The east coast remains calmer and mangrove fishing continues throughout the rainy season, though with less comfort. Offshore fishing is not advisable from June through September.

A useful quirk of Trat's geography: because the islands shelter much of the nearshore water from the worst of the southwest monsoon, inshore fishing in the island channels often remains viable when the open Gulf is too rough for smaller boats.

Recommended Trip Length

Three to four nights suits most anglers who want to experience Trat and Koh Chang as a fishing destination rather than just a beach holiday. This gives time for one mangrove session, one or two reef trips, and a day's flexibility for weather.

Five to seven nights works well for anglers who want to combine serious fishing with the island's hiking, snorkelling, and general beach time — particularly families or groups where not everyone is a committed angler. The combination fishing-beach trip is genuinely one of the better uses of Koh Chang's landscape.

Consider pairing with Rayong to the northwest for a broader Eastern Gulf fishing circuit. The two provinces are roughly 2–3 hours apart by road and offer complementary fishing environments.

Getting There

By air: Trat Airport receives Bangkok Air flights from Bangkok Suvarnabhumi (approximately 1 hour). The airport is about 40km from Laem Ngop ferry pier — taxis and minibuses connect the two. Schedules are limited; book in advance.

By road: Bangkok to Laem Ngop is around 320km via Highway 3 (Sukhumvit Road) continuing east. Driving time is 4.5–6 hours depending on Bangkok traffic. Comfortable first-class buses from Ekamai terminal in Bangkok serve Trat city directly.

Ferry: Regular ferry services connect Laem Ngop to Ao Sapparot pier on Koh Chang's northeastern tip. Journey time is 30–45 minutes. Multiple departures throughout the day; evening services are limited.

Getting around Koh Chang: Songthaews run the main island road on the west coast. Motorbike hire is widely available and is the practical choice for exploring beyond the main tourist strip. For east coast fishing access, a rented motorbike or hired vehicle is recommended.

Where to Stay

Koh Chang's accommodation runs the full range from budget guesthouses behind the beach strips to boutique resorts. The west coast — Hat Sai Khao, Kai Bae, Bang Bao — offers the widest selection. Bang Bao, at the island's southern tip, is particularly useful for anglers: the stilted fishing village has a long pier with direct boat access, several operators, and a handful of guesthouses right on the water.

For mangrove fishing focused on the Trat mainland, staying in Trat city rather than on Koh Chang gives earlier water access and avoids the ferry crossing. Trat city has functional mid-range hotels and a good fresh market.

Sample Three-Day Itinerary

Day 1 — Mangrove session, Trat estuary. Arrive in Trat city by bus or flight the previous afternoon. Early morning (5:30am) kayak or longtail trip into the Trat River mangroves targeting barramundi and mangrove jack in the low-light period. Return for breakfast, afternoon transfer to Koh Chang by ferry. Check in at Bang Bao.

Day 2 — Inshore reef and island channels. Full-day boat charter from Bang Bao pier — morning targeting queenfish and GT in the passes between Koh Chang and Koh Kood, afternoon drifting the inshore reefs for snapper and grouper. Return by sunset. Dinner at the Bang Bao pier restaurants.

Day 3 — Light tackle and island exploration. Half-day kayak session along the south-facing mangrove margins of Koh Chang's east coast, targeting snakehead and jack in the calmer water. Afternoon free for snorkelling, hiking to the island's interior waterfall, or simply exploring the non-tourist east coast villages. Ferry back to Laem Ngop for onward travel.

Conservation Notes

The mangroves of Trat province are ecologically significant — they support juvenile fish nurseries, protect coastlines from erosion, and provide habitat for a wide range of species beyond the fish you're targeting. Fishing in mangrove systems carries particular responsibility: avoid damaging root systems when anchoring or accessing the water, carry out all your waste, and practice strict catch-and-release in sensitive nursery areas.

The reefs around Koh Chang have experienced coral bleaching events in warm years; recovery is ongoing in many areas. Anchoring on live coral — even inadvertently — causes lasting damage. Responsible operators use mooring buoys where available or drift-fish rather than anchor on reef.

Barramundi and mangrove jack are both species that benefit from releasing larger, older fish — these are the breeders that sustain the population. A 50cm barramundi released today will be a 70cm fish in two or three years.
