Koh Larn FAQ — ferry, beaches, money & planning answers

From Bali Hai Pier at the southern end of Pattaya's Walking Street. Take the public passenger ferry (about 40฿ one-way) to Na Baan Pier — and, in season, direct boats to Tawaen Beach Pier — or charter a speedboat that can land at any beach in 15–20 minutes.

The public passenger ferry is approximately 40฿ one-way as of 2026 (raised from 30฿ in April 2026); you pay in cash on boarding. A speedboat seat runs roughly 200–300฿ per person, or about 1,500–2,000฿ to charter the whole boat. Prices change — verify on the day.

The public ferry takes roughly 30–45 minutes depending on the boat and conditions (some newer boats are quicker). A speedboat does it in about 15–20 minutes.

The public ferry typically runs until around late afternoon/early evening, but exact times vary seasonally and by pier. Always confirm the last departure when you arrive, and don't cut it fine — if you miss it, you'll be chartering a speedboat back.

It's at the south end of Walking Street. Take a blue songthaew (baht bus) down Beach Road, a Grab/Bolt or metered taxi straight to the pier, a motorbike taxi, or simply walk from South Pattaya. There's paid parking nearby if you drive, but it fills on busy days.

We rank Samae first for the best all-round swim and snorkel with a calmer crowd, with Tien close behind for quiet beauty. Tawaen is the busiest and best-equipped — ideal for first-timers and families. See our full ranked guide to all eight beaches.

Yes. The west and south beaches — Samae, Tien and Nual — have the clearest, calmest water. Snorkeling is modest compared with the Andaman, but the rocky points hold clear-ish water and tropical fish. Always stay inside the marked swimming zones, clear of boat lanes.

There are eight main swimming beaches — Tawaen, Samae, Tien, Nual (Monkey Beach), Thong Lang, Ta Yai, Laem Tien and Sangwan — plus Na Baan, which is the main village and pier rather than a swimming beach.

It's called Coral Island, but don't expect pristine reef — the coral is patchy and the Gulf water is less clear than the Andaman. You will see tropical fish and some coral around the rocky points of Samae, Tien and Nual on a calm day.

Most people visit as a half- or full-day trip, and that works well. But the island transforms once the last day ferry leaves: quiet beaches, sunset, and a calm morning swim. If you can, stay one night — book ahead, as rooms are limited.

Go early in the day and, if you can, midweek — the island fills up by late morning, especially at weekends and on holidays. Across the year, the cool, dry season (roughly November–February) gives the calmest, clearest sea; the monsoon months (around July–October) can bring rougher water and reduced services.

A half-day covers one beach and a swim; a full day lets you see two beaches plus a viewpoint or watersport; an overnight gives you the quiet island after the day-trippers leave. For a first visit, a full day is the sweet spot.

For a fast, cheap escape to clear-ish water 7 km off Pattaya — yes. Set expectations: it's a busy day-trip island, not a deserted paradise. Go early, pick the right beach for your mood, and it delivers a genuinely good day by the sea.

Very. Tawaen has calm marked swim zones and every facility on tap, Samae offers gentle shelving sand, and the banana boat is cheap group fun. Bring shade, water and reef-safe sunscreen, keep kids inside the roped swim areas, and watch them around the monkeys at Nual.

Tawaen has the widest choice of beachfront seafood and Thai restaurants plus a 7-Eleven; Na Baan village has the most local, best-value food; Samae and Tien have relaxed beachfront restaurants. Ask the price of seafood by weight before it's cooked, and carry cash.

It can be as cheap as a 40฿ ferry and a free swim, or add up fast with loungers, watersports and seafood at island prices. Bring cash, agree prices first, and you can have a great day on a modest budget — see our budget guide.

Shared songthaew taxis run set routes between the village and the main beaches for about 30–50฿ per person; motorbike taxis cover shorter hops. Confident riders can rent a scooter or ATV — but the hills are steep and narrow, so ride only if you're experienced. Some beaches are walkable from the village; others are not.

Only if you're an experienced rider. The island is small but properly hilly, with steep, narrow roads where visitor scooter crashes are common. For most people, shared songthaews are cheaper, easier and far safer.

Bring cash. There's an ATM and a 7-Eleven at Tawaen, plus convenience stores and a few ATMs around Na Baan village, but many beach restaurants, loungers, songthaews and the ferry are cash-only. Thai ATMs also charge foreign cards a fee (around 150฿), so it's cheaper to withdraw on the mainland first.

Mobile signal is good around Tawaen and the developed beaches and patchier on the remote coves. A Thai tourist SIM or eSIM gives reliable data; some restaurants and resorts have wifi, but don't rely on it — download your maps before you go.

Cash, reef-safe sunscreen, water, a hat, and your own snorkel mask if you have one. Water shoes help on rocky beaches, a rash guard saves re-applying sunscreen, and a dry bag protects phones on boats. The quieter beaches have few shops, so don't count on buying essentials there.

Stick to bottled or filtered water, as is standard across Thailand. Buy water at the Tawaen 7-Eleven or village shops before heading to a quiet beach, and carry enough for the day in the heat.

It's challenging — boats are boarded by steps, beaches are soft sand reached via a few steps, and the roads are steep. Tawaen is the most manageable thanks to its pier and flatter, paved frontage. A speedboat that lands directly on a beach, plus a Tawaen base, is the most practical plan; ask operators about assistance in advance.

There are macaques around Nual (Monkey Beach) — don't feed them or leave food and bags unattended. Jellyfish are mainly a monsoon-season concern (roughly May–October): heed any posted warnings or red flags, consider a rash guard, and douse a sting with vinegar (not fresh water). Severe reactions are a medical emergency — call 1669.

The wider Pattaya area has a long-standing reputation for jet-ski damage-deposit disputes. Protect yourself: photograph and film any rental before and after, agree the price clearly up front, wear the life jacket, and never hand over your passport as a deposit. Call the Tourist Police on 1155 if you're pressured.

There's no formal island entry or cleaning fee at the time of writing — you just pay your boat fare. Verify locally on arrival, as things can change. Please take your rubbish with you regardless; bins are limited.
