The short answerTake the public ferry from Bali Hai Pier (about ฿30 each way, ~45 minutes) to Koh Larn for clear water and proper beaches. Speedboats are faster and pricier. Go early, especially in high season.
When Pattaya’s main beach disappoints, Koh Larn delivers the postcard: turquoise water and white-ish sand a short hop offshore. It’s the day trip nearly everyone enjoys.
Getting there
Public ferries leave from Bali Hai Pier at the south end of Walking Street, roughly ฿30 one way, taking about 45 minutes to Na Ban (the main village) or Tawaen Beach. Speedboats run on demand for more money and a 15-minute crossing.
The beaches
- Tawaen — the biggest and busiest, with sunbeds, food and watersports.
- Samae — pretty and a bit calmer.
- Nual (“Monkey Beach”) — smaller and quieter.
- Tien — the laid-back, low-key choice.
Getting around the island
Shared songthaews meet the ferry; many visitors rent a scooter (only if licensed and confident). Bring cash, reef-safe sunscreen and water.
Day-trippers crowd the main beaches midday. Go on an early ferry, or stay a night to have the place to yourself after the boats leave.
