Koh Larn Day Trip: Take the Ferry Yourself or Book the Tour?

Take the ferry yourself. It is 40 baht each way, about 40 minutes, and leaves from Bali Hai Pier at the end of Walking Street — and the single most important number on this page is that the last boat back from Na Baan leaves at 18:00, and the last one from Tawaen at 17:00. Book a tour only if you specifically want the water sports and lunch bundled, and know that the cheapest packaged speedboat day trip costs roughly the same as doing it yourself.

The ferry, and the fare nobody has updated

The public ferry runs from Bali Hai Pier, at the southern end of Pattaya Beach Road past Walking Street. It lands either at Na Baan Pier, the main village, or on selected departures goes direct to Tawaen Beach. At the end of the pier, the Tawaen boat is on the left and the Na Baan boat on the right. You can come back from whichever pier suits you, regardless of where you landed.

The fare rose from 30 to 40 baht one way on 10 April 2026, a flat rate for everyone, after sixteen years unchanged. Worth knowing: operators first announced they would postpone the rise as a Songkran gift after the Chonburi governor asked them to, then implemented it on the 10th anyway.

Here is the honest complication. Several sources published after that date — including a Pattaya Mail travel guide from August 2026 — still quote 30 baht. Either the increase was quietly walked back or a lot of publishers never updated. Carry 40 and expect to pay 40. If it is 30, you are 10 baht up.

Crossing time is quoted anywhere from 30 to 45 minutes depending on who you ask. Budget 45 and you will not be caught out.

The timetable, and the trap

No government body publishes an official Koh Larn timetable. The schedule below is the most detailed one available, from a Thai-language source dated May 2026, and it is broadly corroborated by two other recent guides. Treat it as reliable but not guaranteed.

Two things catch day-trippers out. The first is that last 17:00 from Tawaen — if you are on Tawaen and miss it, you need to get yourself across to Na Baan for the 18:00. The second is newer and almost nobody has written about it: since September 2026, songthaews on Koh Larn are not permitted to pick up or drop off passengers after 3pm. That rule came in after a series of brawls between speedboat operators, along with police patrols from 2pm and a requirement that tickets be bought at each company's designated counter. If you are on a far beach at four in the afternoon, getting back to the pier is now genuinely harder than it used to be.

Rough seas cancel sailings, most often between May and October. The practical check is the Koh Larn Municipality Facebook page on the morning you travel.

Ferry versus speedboat versus a packaged tour

A shared speedboat runs roughly 150–400 baht per person one way depending on who you book with — the quoted ranges vary that widely between sources — and takes 15 to 20 minutes. It leaves when full and it can be very bumpy. A private charter is somewhere between 1,000 and 3,500 baht. Speedboat services are also the first thing suspended when the sea is up.

On packaged tours, here is the comparison that actually matters. Checking Klook's Coral Island listings:

• The popular full-day tour with water activities is about US$27.25, rated 4.6 from around 3,600 reviews.
• But there is a speedboat full-day tour at about US$12.65, and half-day island-hopping with snorkelling at around US$17.
• At the top end, essentially the same day costs US$52 or more, and one listing runs past US$100.

Doing it yourself costs 80 baht in ferry fares, maybe 60 baht in songthaews and 100 baht for a sunbed — call it 250 baht, under US$8, plus whatever you eat. So the cheap packaged tour at US$12.65 is barely more than going independently, and the US$27 one is a comfort purchase: hotel pickup, a guide, lunch sorted, water sports arranged. That is a perfectly reasonable thing to buy. Just buy it knowing what the alternative costs, rather than assuming the tour is the only way across.

Which beach to pick — this is where most people go wrong

Almost everyone ends up on Tawaen because the ferry docks there and the tours go there. It is the worst beach on the island for most of what people actually want.

If you want to swim and snorkel, go to Tien. If you want to eat well and watch the sunset, go to Samae. Go to Tawaen only if you specifically want a jet ski.

Getting around the island

Songthaews run from the pier to the beaches, and the published fares contradict each other badly — one guide gives three different ranges on the same page. Expect somewhere between 20 and 40 baht a hop, around 10 to 15 minutes from the pier, and agree the price before you get in. Pattaya City said in 2025 it planned distance-based fare guidelines to stop price gouging; as of now, none have been published.

Scooter rental runs roughly 200–400 baht a day, and both the sources that quote it advise against renting if you are not a confident rider. The island's hills are steep. There is also more regulation here than guides suggest: a 2025 reform classified the island's 3,500-plus vehicles into nine categories, closed Koh Larn for fourteen days to survey and register them, and now issues stickers carrying driver identification so complaints and accidents trace to a specific operator. Any increase in vehicle numbers needs sign-off from at least two of Pattaya City, Pattaya Police and the Banglamung District Office. Rental shops are also being checked for licence verification and helmet use.

Bring cash. ATMs on the island are limited and many businesses do not take cards. Ferry tickets are cash only too.

Sunbeds, water sports and the jet ski problem

Beach chair prices on Koh Larn are quoted between 50 and 200 baht depending on the source, and roughly 100 baht with an umbrella is the most commonly cited figure. Some beachfront restaurants waive the charge if you order food or drinks, which is usually the better deal. Confirm the price before you sit down.

On jet skis: the Pattaya-area scam is real and well documented. A first-person account published in July 2026 describes 5,000 baht being demanded for scratches “pointed out” after a fifteen-minute rental. The published advice is worth following exactly — do not negotiate directly with the operator; contact the Tourist Police immediately; photograph and video the craft from all angles before you take it out; and keep that documentation. We will note fairly that the July 2026 account does not specify whether it happened on Koh Larn or on Pattaya Beach. What is documented on Koh Larn specifically is a run of brawls between speedboat operators over passengers and pricing in August and September 2026, which is what prompted the new rules.

Is the island actually worth it?

Yes, with eyes open. The water really is clear in a way Pattaya's and Jomtien's are not, and on Tien or Ta Yai you get a genuinely good Thai beach forty minutes from Walking Street for the price of a coffee.

The honest caveats: the island is under real pressure. Its incinerator handles 50 tons a day against a backlog of more than 50,000 tons, and until recently it had just two wastewater treatment ponds, at Tawaen and Samae, with a third system rated at 1,600 cubic metres a day only recently built. Visitor caps have been proposed repeatedly since at least 2017 and no cap has ever been introduced. A committee met in September 2026 to draw up rules for jet skis, parasailing boats and other water operators across Pattaya, Jomtien and Koh Larn, but no specific rules have been set yet.

On staying overnight: there are simple bungalows near Tawaen and Tien, and the advice is to book ahead for Friday to Sunday. We could not find any credible current pricing or inventory, so we are not going to pretend otherwise. For most people a day trip is the right call — just catch the boat back.
