Railay Beach is one of Thailand\’s most dramatic destinations — a limestone peninsula completely cut off from the mainland by steep karst cliffs, accessible only by longtail boat. Despite being just 15 minutes from Ao Nang, it feels a world apart: white sand beaches, turquoise water, towering rock walls, and some of the best rock climbing in Southeast Asia. This guide covers how to get there, what to do, and where to stay.

How to Get to Railay Beach
Railay is only accessible by boat — there are no roads connecting it to the mainland. The main departure point is Ao Nang Beach, 15 minutes away by longtail. Boats operate daily from 08:00 to 18:00 and depart when full (approximately every 15–20 minutes in high season). After 18:00, private charters are available but cost significantly more.
From Ao Nang (Main Option)
Walk to the southern end of Ao Nang Beach and you\’ll find the longtail boat service. The standard fare is 100 THB per person each way — one of the best value boat rides in Thailand. The journey takes 10–15 minutes depending on sea conditions and arrives at Railay West Beach. No advance booking needed — just show up, pay, and wait for the boat to fill.
ℹ️ Longtail boats operate 08:00–18:00 only. After 18:00, private charter rates apply — approximately 1,200–1,500 THB for the whole boat. If you\’re staying on Railay and want to visit Ao Nang\’s night market, factor this in.
From Krabi Town
Two options from Krabi Town: take a Grab or taxi to Ao Nang (~20–30 minutes, ~400–500 THB) and then a longtail to Railay, or take a songthaew to Ao Nang for 60 THB (slower, ~40 minutes) and then the longtail. There are also longtail boats from Krabi Town pier directly to Railay East (~45–60 minutes, ~150 THB) but these are slower and less frequent.
From Krabi Airport
A private transfer from Krabi Airport to Ao Nang costs around $14 USD (~30 minutes). Alternatively, a shuttle bus runs hourly from 08:00–20:00 for around $4 USD. Then take the longtail from Ao Nang to Railay as above.
Railay\’s Four Beaches
Despite being a small peninsula, Railay has four distinct beaches — each with a different character. The peninsula is small enough to walk across in 10 minutes.
Railay West (Arrivals Beach)
Where longtail boats from Ao Nang arrive. The beach itself is pleasant but not the best on the peninsula — the water can be shallow at low tide and there\’s more boat traffic. Most accommodation and restaurants are on this side. Good sunsets.
Railay East (The Mangrove Side)
Faces east toward Krabi Town — mangroves and tidal mudflats rather than a swimming beach. Where longtail boats to Krabi Town depart. The path connecting East to West is where most of Railay\’s guesthouses, restaurants and climbing shops are.
Phra Nang Beach (Best Beach)
A 10-minute walk south of Railay West — and one of the most beautiful beaches in Thailand. Dramatic limestone towers backdrop a perfect crescent of white sand and turquoise water. The famous Phra Nang Cave (Princess Cave) is at the southern end — a shrine filled with phallic offerings that\’s become something of a tourist curiosity. Day trippers flood in from 10am; be here before 09:00 or after 16:00 for any peace.
Tonsai Beach
Beyond Phra Nang, accessible by a rocky scramble at low tide or by longtail. The budget traveler and rock climber enclave — more basic, more social, better value accommodation than Railay West. Only accessible on foot during low tide; at high tide, take a longtail from Ao Nang or Railay West (100 THB).
What to Do on Railay
Rock Climbing
Railay is one of Southeast Asia\’s premier rock climbing destinations — hundreds of bolted routes on perfect limestone, ranging from beginner to elite level. Half-day beginner courses start from around 800–1,000 THB per person, including equipment and instruction. Popular operators include King Climbers, Base Camp, and Tex Rock Climbing. The most famous route is Humanality (8b) on the Diamond Cave wall.
The Viewpoint and Diamond Cave
A steep 20-minute climb from Railay East leads to a viewpoint overlooking both sides of the peninsula — spectacular views of Ao Nang, the islands, and Phra Nang. The trail continues to Diamond Cave, a cave system with stalactites. Not for those afraid of heights — the final section uses fixed ropes on bare rock. Free entry.
The Hidden Lagoon (Sa Phra Nang)
A secluded lagoon hidden inside the cliff walls, reached via a demanding scramble up fixed ropes — steep, slippery, and not for the faint-hearted. The climb takes 20–30 minutes and the lagoon is only accessible at lower tides. The reward is a completely enclosed green pool surrounded by vertical rock. Worth it for the fit and adventurous.
4 Islands Day Trip
Longtail or speedboat tours from Railay visit Koh Poda, Koh Gai (Chicken Island), Koh Tub, and Koh Mor — a half-day of snorkeling and beach hopping. From ~600–1,200 THB per person depending on boat type. Book at any travel agent on Railay West.
Best Time to Visit
- November–April (high season): Calm seas, sunny weather, longtail boats run reliably all day. Most crowded December–February.
- May–October (low season): Monsoon — longtail boats may not run in rough weather. Some days the crossing is cancelled. The landscape is dramatically green and beautiful when it\’s not raining. Accommodation prices drop significantly.
Where to Stay on Railay
- Railay West (main beach side): Most resorts and mid-range accommodation. Rayavadee Resort is the luxury option — directly on Phra Nang Beach. Most guesthouses from ~$40–120 USD.
- Tonsai Beach: Budget bungalows and climbers\’ hostels. Most basic but most social. From ~$15–40 USD.

Practical Tips
- No ATMs on Railay — withdraw cash in Ao Nang or Krabi Town before crossing
- After 18:00 — longtail public service stops; private charter ~1,200–1,500 THB for the boat
- Phra Nang Cave: Respect the shrine — it\’s a genuine place of worship for local fishermen
- Day trippers peak 10:00–15:00 — Phra Nang Beach is best before 09:00 or after 16:00
- Wading to board: Longtails don\’t come to shore — you wade in shallow water to board. Waterproof your phone and keep electronics in a dry bag
