If Pattaya Beach is the city's tourism storefront and Wong Amat is the family-friendly residential alternative, Koh Larn — Coral Island — is where you actually go to swim in clear water on white sand. The water at the mainland Pattaya beaches is fine, but it's not the famous postcard turquoise; that you find offshore at Koh Larn.
Located 7 km west of Pattaya, reached by a 30-minute ferry from Bali Hai Pier (with speedboat options as fast as 15 minutes), Koh Larn is the classic Pattaya day-trip. The island has six main beaches, each with different character, water sport operators, and food scenes. Tens of thousands of visitors make the crossing every week — and unlike many overrun island day-trips in Southeast Asia, Koh Larn still genuinely delivers what it promises: clearer water, whiter sand, and a proper "tropical island" experience without flying anywhere.
The six beaches
| Beach | Vibe | Best for |
|---|---|---|
| Tawaen Beach | Largest, busiest, most touristy | First-timers, families, water sports |
| Samae Beach | Smaller, more party-vibe, restaurants | Couples, groups, food + drinks |
| Tien Beach | Quieter, scenic, snorkeling-friendly | Snorkelers, photographers |
| Nual Beach | Quietest, white sand, cliffside | Couples, peaceful day |
| Ta Yai Beach | Local Thai favourite, less commercial | Avoiding tourists |
| La Beach | Small, harder to reach, local fishermen | Off-tourist explorers |
Tawaen is the default first visit — the ferry from Bali Hai mostly lands here. It's the most crowded but has the most operators, food, and full water sport setup. Most visitors take a tuk-tuk or scooter from Tawaen to one of the other beaches once they arrive on the island.
Sport-related activities
Koh Larn is one of the densest concentrations of water sport operators in Pattaya:
| Activity | Where | Notes |
|---|---|---|
| Beach swimming | All 6 beaches | Clearer water than mainland Pattaya |
| Parasailing | Tawaen + Samae | The signature Koh Larn experience |
| Banana boat | Tawaen + Samae | Family-friendly group ride |
| Jet ski | Tawaen | Use reputable operators only |
| Snorkeling | Tien, Nual | Best visibility 6–18 m water |
| Intro scuba dive | Tawaen + Samae | Non-cert "Discover Scuba" usually |
| Sea walker / underwater walking | Tawaen | Helmet-tube novelty experience |
| Beach volleyball | Tawaen, Samae | Pickup games on the sand |
| SUP / kayak | Quieter beaches | Bring own or rent locally |
| Glass-bottom boat tour | Multiple operators | Ferry-and-tour combo |
Most water sports run 09:00–16:00 — operators wind down before the last ferry returns at sunset.

How to visit
The fastest path: Bolt/Grab to Bali Hai Pier at the southern end of Walking Street, ~07:30. Buy a public ferry ticket (~฿30) for the next outbound boat. Sail to Tawaen Beach. Walk or tuk-tuk to whichever beach matches your day — Samae for food/drink energy, Tien for snorkeling, Nual for a quiet couples day. Stack 1–2 water sports if budget allows. Return to Tawaen by 16:30 for the last public ferry around 18:00.
For families or first-timers: book a day-tour package that includes pickup, speedboat, parasailing, banana boat, lunch, and return — usually ฿1,500–฿3,000 per person, takes the schedule logistics off you.
For snorkelers: skip the package, take the public ferry, hire a longtail boat for ~฿800–฿1,500 to take you to the better snorkeling drops off Tien or Nual, and bring your own mask + snorkel from the mainland to avoid rental scarcity.
For Pattaya travellers planning a "best of Pattaya beaches" tour: pair Koh Larn (Day 1) + Wong Amat Beach (Day 2 morning) + Pattaya Beach Public Aerobics (Day 2 sunset) for a full beach-and-water-sport week. The Pattaya beach ecosystem is more varied than the headlines suggest once you know where to go.
