TL;DR: Coral Island is Koh Larn, a small island about 7km off Pattaya with far clearer water than Pattaya’s main beach. Get there on the public ferry from Bali Hai Pier (
฿40 / US$1.20, up from ฿30 in April 2026, 40-45 minutes) or a shared speedboat (฿150-300 / $4.50-9, 15-20 minutes). Tawaen, where the ferry lands, is the busiest beach with tour groups and watersports touts; Samae, Nual and Tien are calmer and better for swimming. A scooter (฿300-400 / $9-12/day) or songthaew (฿40-70 / $1.20-2.10 a ride) gets you around. It works well as a day trip on an early ferry. All prices at ฿33 = US$1 (July 2026).
If you’ve spent an afternoon on Pattaya’s main beach and wondered why the water looks the color it does, Coral Island is the answer everyone eventually gives you. It’s the local tourist name for Koh Larn (“larn” is Thai for coral), a small island roughly 7km offshore that gets a fraction of Pattaya’s development but noticeably clearer, calmer water, plus four distinct beaches ranging from a full-on tour-bus scene to a near-empty cove. This guide covers how to get there, which beach actually suits you, what snorkelling and watersports cost, and the parts of the island worth being honest about before you go, so it slots in naturally next to the wider things to do in Pattaya pillar guide.

Getting to Coral Island: ferry, speedboat or tour
| Option | Price | Duration | Departs from | Notes |
|---|---|---|---|---|
| Public ferry | 40-45 min | Bali Hai Pier | Cheapest option; up from ฿30 in April 2026; runs roughly 7am-6pm; pay at the kiosk by the boat, no booking needed | |
| Shared speedboat | 15-20 min | Bali Hai Pier | Faster but a genuinely bumpy ride; several operators run these back-to-back | |
| Private speedboat charter | 15-20 min | Bali Hai Pier | Price depends on boat size and group; useful for groups timing their own return | |
| Organised day tour | Varies by operator | Half-day to full-day | Hotel pickup or Bali Hai Pier | Usually bundles return speedboat, lunch and watersports add-ons |
The public ferry from Bali Hai Pier is the budget option almost everyone ends up taking: about ฿40 (~US$1.20) per person each way (up from ฿30 after an April 2026 fare adjustment), running roughly 40-45 minutes, with departures from early morning (around 7-8am) through to late afternoon. There’s no advance booking; you simply pay a small fee at the ticket kiosk next to the boat before it leaves. Ferries land at either Naban Pier (the main village, on the side facing Pattaya) or Tawaen Beach (the busiest beach, on the opposite side), so check which one your boat is heading to if you have a specific beach in mind.
If you’d rather skip the slower crossing, shared speedboats leave from the same pier for about ฿150-300 (~US$4.50-9) and take only 15-20 minutes, though it’s a rougher ride than the ferry. Private charters run from roughly ฿1,500 up to ฿3,500 (~US$45-105) depending on the boat and how many people you’re splitting it with, and give you control over your own return time rather than working around ferry departures. The last return ferry from Koh Larn is commonly cited around 5:30-6pm, so build your day around getting back to the pier well before then.
The beaches: which one to pick
| Beach | Vibe | Best for | Note |
|---|---|---|---|
| Tawaen | Busy, commercial, full amenities | First stop, photos, food, ferry access | Longest beach (~685m) but sees 2,000-5,000+ visitors a day; jet skis and touts are constant |
| Samae | Breezy, moderate crowds, grainy sand | Sunset views, long walks | West-facing, so it’s the pick for watching the sun go down |
| Nual (Monkey Beach) | Quieter, clearest water | Snorkelling, swimming | Southern tip of the island; wild monkeys on the hillside, feeding is popular but optional |
| Tien | Calm, scenic, no direct road access | Relaxing, fewer crowds | Reached by boat drop-off or a short walk from the main road, which naturally limits numbers |
Tawaen Beach is where the public ferry usually docks, and it shows: it’s the island’s longest beach at around 685m but also the busiest by a wide margin, with more than 25 restaurants, dozens of souvenir shops, and a constant churn of jet skis and banana boats. It’s the right place to land, get your bearings, grab food and take the obligatory photo, but not where you want to spend the whole day if quiet water is the goal.
Samae Beach, on the island’s west side, is calmer and known for its breeze and sunset outlook, though the sand is coarser than the other beaches. Nual Beach, at the island’s southern tip and also known as Monkey Beach for the troop that lives on the hillside above it, has noticeably clearer water and is generally rated the best spot for beach-accessible snorkelling. Tien Beach has no direct road access, so you either get dropped by boat or walk about five minutes in from the main road; that small barrier to entry keeps it one of the calmer, more scenic beaches on the island.
What’s the snorkelling and watersports scene like?
Snorkelling is decent rather than spectacular, best off Nual Beach where the water is clearest, with basic gear rentable on most beaches for a small daily fee. Parasailing runs about ฿300-500 (~US$9-15) per person, though some operators quote closer to ฿800 once you’re at the counter and add extras, so agree the price up front. Jet skis cost roughly ฿700-1,500 (~US$21-45) for 30 minutes, and banana boats run about ฿200-300 (~US$6-9) per person. These are available directly off Tawaen, Samae and Nual beaches from beachfront operators rather than needing to be booked ahead.
Are there good viewpoints on Koh Larn?
Yes. Khao Nom viewpoint, near Samae Beach, looks out over the island’s hilly, forested interior, Samae Beach itself, and a scatter of small islets in the Gulf of Thailand. The Tawaen Beach viewpoint sits higher and gives a wider 360-degree view, including a distant look back at the Pattaya skyline, and it sits close to the hilltop Big Buddha statue that overlooks Tawaen Beach. Both are reachable by scooter or a short motorbike-taxi trip from the main roads.
How do you get around the island?
Scooter rental is the most practical option for covering multiple beaches in a day, at about ฿300-400 (~US$9-12) for 24 hours, usually including fuel, available near the main pier and around Tawaen Beach. Songthaews (shared pickup-truck taxis) wait near the pier and at each beach, charging roughly ฿40-70 (~US$1.20-2.10) per person depending on distance. Motorbike taxis are also common, with fares fixed and posted on tourist maps. Note that golf cart rentals have been discontinued on the island over safety concerns with inexperienced drivers on the narrow roads, so don’t plan around finding one.
Day trip or overnight: which should you do?
For most visitors, a day trip is plenty. Take an early ferry or speedboat, head straight for a quieter beach like Nual or Tien rather than lingering at Tawaen, and time your return around the last afternoon ferry. Staying overnight only really pays off if you specifically want to experience the island once the day-trip crowds clear out, since the beaches empty out noticeably after about 5pm when the tour boats stop arriving. Guesthouses on Koh Larn are simple and inexpensive (roughly ฿400-800 / US$12-24 a night for budget options), which makes an overnight stay a low-cost add-on rather than the main reason to visit. If you’re building a full itinerary, Coral Island slots naturally into the Pattaya 3-day itinerary as a single day, and pairs with a look at where to stay in Pattaya if you’re deciding between a Pattaya base and an island overnight.
Honest downsides
Coral Island is a genuine step up from Pattaya’s main beach, but it isn’t an undiscovered paradise, and it’s worth knowing the catches before you go.
- Tawaen Beach is genuinely crowded. It regularly sees several thousand visitors a day, most of them tour groups arriving in waves, and the beach itself is a fairly narrow strip packed with sunbeds, jet skis and vendors. It’s not the relaxing swim you may be picturing.
- Watersports touts push hard. Jet ski and parasailing operators on the beach are known for hard-selling add-ons once you’ve stopped at their counter, and jet-ski damage-claim disputes (being told you scratched a machine you didn’t) are a recurring complaint. Agree prices and time limits before you pay, and film the jet ski’s condition from every angle, with the operator in shot, both before and after you ride.
- It gets busy fast in the middle of the day. The window between roughly 10am and 2pm, when day-tour boats and speedboats are all arriving at once, is the most crowded stretch. Early morning or late afternoon is noticeably calmer.
- The “clear water” reputation is relative to Pattaya, not the whole Gulf of Thailand. Coral Island’s water is a genuine improvement, but if you’ve been to Koh Samet or further south, temper your expectations; it isn’t turquoise, postcard-clear everywhere.
- The public ferry has a real cutoff. The last boat back to Bali Hai Pier leaves in the late afternoon (commonly cited around 5:30-6pm). Miss it and you’re paying for a private speedboat back, so keep an eye on the time once you’re a few beaches deep into the day.
If quiet water without the ferry crossing is what you actually want, compare it against Pattaya Beach itself first; Coral Island is the better swim, but Pattaya’s main beach wins on convenience if you’re short on time.
