What a fishing trip from Koh Lanta actually involves

Most fishing trips from Koh Lanta are sold as a boat, some rods and a few hours on the water. That leaves out what decides the day: which method suits your group, what lives here, whether you can keep your catch, and where fishing is legal at all. This guide answers those, with the law checked against the official texts on 18 October 2026.

Mu Ko Lanta National Park

134 km²

Maximum fine for bringing fishing tools into a park

10,000 THB

Maximum penalty for taking wild animals in a park

What a fishing trip from Koh Lanta involves

A typical trip is a private boat for your group, a longtail or a speedboat, out for a half or full day, with rods and tackle supplied. You fish one or two methods, depending on the water and the target. On our private boat trips page you can see how we arrange fishing days, with fishing gear available, so you do not need to pack rods.

Expect the boat, route and method to be chosen together, and sea conditions to decide more than any brochure does.

Fishing methods on the Andaman coast

Four methods cover most recreational fishing around Koh Lanta. Pick by temperament as much as by fish.

Method	How it works	Typical targets	Time of day	Suits
Trolling	Lures pulled behind the moving boat	Mackerel, barracuda, trevally	Often early or late in the day	Groups who like to cruise and wait
Bottom fishing	Baited hooks dropped to the reef or seabed	Groupers, snappers, reef fish	Any time; tide matters	Families and beginners
Jigging	A metal lure dropped deep and worked upwards	Trevally, groupers, snappers	Daytime	Fit, keen anglers
Squid fishing	Lights draw prey, squid jigs are cast	Squid	After dark	Families and mixed groups

Bottom fishing is the gentlest start: the boat sits still, the bites are frequent on a good spot, and children can join in. Jigging is physical, with heavy lures and repeated lifts. Trolling means long spells of waiting, then a sudden run on the reel. Times of day here are the usual angling pattern, not a rule; the person running your trip will know what is working that week.

Night fishing on Koh Lanta for squid

Night fishing around Koh Lanta usually means squid. Bright lamps over the water attract plankton and small fish, and squid follow them up into the light. NASA describes exactly this for the blue and green lights that dot the Andaman Sea in a photo from 20 April 2026. Anglers then cast or drop squid jigs, small lures with rows of fine hooks, and lift them gently.

A Department of Fisheries study counts nine loliginid squid species in Thai waters, three of them found only in the Andaman Sea. An evening trip depends on sea state and on what can be arranged for your date, so ask before planning around it.

What you might catch, with no promises

No honest operator promises a species. FishBase, the global fish database, lists these fish as native to Thai waters, and all are familiar to Andaman anglers:

• giant trevally, a reef predator that reaches about 1.7 m;
• narrow-barred Spanish mackerel, a fast open-water fish taken by trolling;
• great barracuda and cobia;
• orange-spotted grouper and mangrove red snapper, around reefs and rocks.

Most days bring a mix of smaller reef fish. Size and numbers depend on the method, spot, tide, moon and season.

Fishing in a national park in Thailand

Inside a national park, catching animals is against the law. That matters near Koh Lanta, because two marine national parks cover many of the islands that boats visit.

What the National Parks Act says

Section 19 of the National Parks Act B.E. 2562 (2019), in the Office of the Council of State’s unofficial English translation, lists acts banned within a national park. Two apply to fishing:

• item (3): luring or taking wild animals away or injuring wild animals in any manner;
• item (7): bringing into the park tools for hunting or catching animals.

The Act’s “wild animal” follows the Wild Animal Conservation and Protection Act B.E. 2562, which covers animals of all species living freely in nature. On that wording, fish and squid are included. Under sections 43 and 45, item (3) carries up to five years in prison, a fine of up to 500,000 THB, or both; item (7), a fine of up to 10,000 THB. Section 22 lets park officials permit item (7) for listed purposes, but not item (3). Only the Thai text published in the Government Gazette on 29 May 2019 has legal force.

Parks enforce this. In March 2024 the Phi Phi national park asked police to prosecute tourists who dived and collected a shellfish, citing section 19, Daily News reported.

Which waters near Koh Lanta are park

• Mu Ko Lanta National Park: a marine park since 1990, 134 km², including the southern tip of Koh Lanta Yai, Koh Rok, Koh Ngai and Koh Talabeng, according to Thai National Parks. The park also manages Koh Haa, which it closed for two days in June 2026 and again from 1 August to 30 September.
• Hat Chao Mai National Park (Trang): Koh Mook, Koh Kradan, Koh Chuak and Koh Waen, which close for part of each monsoon on dates the department sets every year.

These are the islands of the snorkelling trips compared in our Koh Rok, 4 Islands or Phi Phi guide. We have not found a published map of the parks’ sea boundaries, so ask whoever runs your trip where they fish relative to them.

Can foreigners go fishing in Thailand?

Yes. Visitors fish as recreational anglers on hired boats, under the same rules as Thai anglers. The Fisheries Act B.E. 2558 (2015) licenses fishing gear listed in ministerial regulations and fishing in the zones it defines; the coastal zone runs up to 3 nautical miles from shore. It has been amended since, and we found no Department of Fisheries rule creating a personal licence for a visitor with a rod. We could not confirm the current position directly, so treat this as unverified and check that your boat’s paperwork covers the trip.

Catch and release, or catch and cook on Koh Lanta

Decide before you leave the shore. Inside a park the answer is already made: nothing is taken. Outside park waters, agree three things in advance: whether fish may be kept, which ones are released, and who cleans and cooks them. Releasing undersized fish and anything you will not eat is good practice.

Many visitors want their catch cooked the same evening. That can often be arranged, but where and by whom depends on the trip, so ask when you book. One caution from FishBase: large giant trevally, barracuda and mangrove red snapper may carry ciguatera toxin. If you hope to eat your catch, ask locally which fish are safe to keep and eat.

Choosing a Koh Lanta fishing charter format

The choice is mainly boat and length.

• Longtail, half day: close to shore, short crossings, good for families and first-timers.
• Speedboat, half day: more range in the same time, with a livelier ride.
• Full day: time to reach spots further out and combine methods, or to add a swim stop.

For when a private boat is worth it over a shared tour, see when a private boat trip from Koh Lanta makes sense. Shared island tours are on our Koh Lanta boat tours page.

Sea conditions, seasickness and sun

The calmer half of the year, roughly mid-October to mid-May, gives the most dependable days. In the southwest monsoon the sea can be rough: on 31 May 2026 the Thai Meteorological Department warned of waves of about 2 m in the Andaman Sea south of Krabi. For 2026 the park scheduled Koh Rok closed from 1 June and Koh Haa from 1 August, both to 30 September, which tells you how it reads the season. Our rainy season guide covers what still runs.

A boat that stops to fish rolls more than one that is moving. If anyone is prone to seasickness, take tablets before boarding as the packet directs, eat lightly, look at the horizon and choose a half day. Bring a hat, long sleeves, sunscreen and more water than you think you need: there is little shade on a longtail.

What to send us before a fishing trip

Say whether you want a half or full day, daytime or evening, and whether you hope to keep and eat your catch. We will reply with the options, the price and availability, and we can explain where the trip fishes and how the catch is handled.
