Railay Beach is a peninsula in Krabi Province, southern Thailand that, although attached to the mainland, is walled off by towering limestone karst cliffs and has no road access, so it can only be reached by boat. It is famed for the white sands of West Railay, the mangrove-lined east side, the emerald cove of Phra Nang Cave Beach, and world-class rock climbing. A short 15-20 minute long-tail boat ride from nearby Ao Nang makes this hidden paradise easy to reach.

Good to know
CautionBeware of inflated long-tail boat fares. The shared Ao Nang-Railay boat is typically around 100 baht one-way / 200 baht return (verify current rates), but private charters are often overquoted — always agree the price before you board.
RulesThe Ao Nang boat cooperative and the Railay cooperative do not honor each other's tickets. Trying to board the wrong co-op's boat may get you refused and force you to buy a new ticket, so confirm where your return ticket is valid.
MannersThe Phra Nang Cave Shrine is still a sacred site used by locals. Don't move or mock the offerings, keep your voice down, and don't climb on anything. Dress respectfully (cover shoulders and knees) at the shrine.
SafetyWest Railay is shallow, so swim at high tide for safety, watch for boats and rocks, and note currents can strengthen in the wet season. The Princess Lagoon must be timed with high tide — at low tide it becomes a mud pit.
SafetyThe walking path from Railay East to Phra Nang is a monkey hotspot. Never feed them — monkeys habituated to food turn aggressive and snatch belongings.
SeasonThe dry high season (Nov-Apr) offers clear skies and calm seas, ideal for swimming and climbing. The wet season (May-Oct) brings downpours and rough seas that can delay or cancel boats — check the weather and sailings.
Practical info
Take a shared long-tail boat from Ao Nang Beach or Ao Nam Mao Pier (~15-20 min; boats usually leave once 8 passengers board). There are no roads on the peninsula — get around on foot. Visit before crowds around 8-9 am or after 3 pm. Fares and schedules vary by season and cooperative, so confirm the latest on site.
