Short answer
Phra Nang Beach sits at the southern tip of the Railay peninsula in Krabi, with no road: you arrive by longtail boat from Ao Nang in about 15 minutes or on foot from Railay East or West. Entry to the beach and the cave shrine is free; toilets cost 10 baht, according to Thai Holiday Guide. The shrine holds hundreds of carved wooden phalluses left by fishermen. The beach is busiest from about 11 am to 3 pm, so go early, and check the tide.
What Phra Nang Beach is, and why it has no road
Phra Nang Beach, also called Phra Nang Cave Beach, lies at the southern tip of the Railay peninsula. Thai Holiday Guide describes a stretch of white sand walled in by sheer limestone cliffs on three sides, reachable only by longtail boat or jungle footpath. Wikipedia says the whole Railay peninsula is accessible only by boat, because high limestone cliffs cut off the mainland, and that Phra Nang is one of its four main areas.
Entry to the beach and to the cave is free, according to Thai Holiday Guide, and the only charge on site is 10 baht for the public toilets. Phuket 101 adds that the beach has no shops, bars or restaurants, because a resort occupies the whole shore, though a few longtail boats converted into floating bars anchor off the sand in the day. Carry your own water and food.
The shrine in the cave: what it is and how to behave
Phra Nang means sacred princess. Thai Holiday Guide says a shallow cave at the eastern end of the beach holds the Phra Nang shrine, where fishermen leave carved wooden phalluses and ask a legendary princess spirit for safe voyages and good catches; it says the shrine holds hundreds of offerings. Wikivoyage calls it a small shrine in a small cave, dedicated to the spirit of a drowned princess. Phuket 101 says legends differ on who she was.
The cave is not large or deep, and Phuket 101 says there is always a crowd taking photographs, and it calls some of that behaviour disrespectful. It is a shrine, so treat it as one: keep voices down, do not touch the offerings and ask before you photograph people. Thai Holiday Guide says local boat operators still stop here before moving on to other Railay beaches, out of respect for the tradition.
Getting there: boat from Ao Nang, or a short walk from Railay
The usual route is a longtail from Ao Nang. Thai Holiday Guide gives about 15 minutes, and Phuket 101 gives a fare of 200 baht return, with boats leaving when ten passengers are on board. Wikivoyage's older notes quote 80 to 100 baht one way, so the fare has been steady at about 100 baht each way. Boats from Ao Nang land at Railay, and you then walk to Phra Nang. Wikivoyage adds that there is no pier at Ao Nang, so expect wet feet.
On foot, Wikipedia describes a public trail from the southern end of the East Railay boardwalk, under overhanging limestone cliffs, to Phra Nang Beach, and Phuket 101 says short alleys connect the beaches so you do not need a boat from Railay West. Wikivoyage says any two landmarks on Railay are a five to ten minute walk apart. If you stay at Railay, you can walk to Phra Nang early, before the day boats arrive.
Crowds: when the sand fills up and how to avoid it
Time your visit. Thai Holiday Guide says that from roughly 11 am to 3 pm, day-trip boats from Ao Nang and Phi Phi stack up on the beach and the narrow strip of sand gets genuinely crowded. It adds that the 8 am longtails from Ao Nang carry a fraction of the passengers that the 11 am and noon boats do, on the same ride at the same price. Wikivoyage notes that in high season most of the beach is taken up by longtails, with space left in the left and right corners.
Thai Holiday Guide also suggests walking in from Railay East or West rather than arriving by tour boat if quiet is the point. Late afternoon, once the tour boats have thinned out, is the other quiet window, according to the same page. If you want a swim, go early and leave before the middle of the day.
Tide, sea and what to bring
Tide matters here. Thai Holiday Guide says that at low tide the sand stretches wide and flat in front of the cave, while at high tide it narrows considerably and the walk around the eastern rocks toward the shrine can mean wading. Check a tide chart or ask your boatman before planning a long stay. Wikivoyage says the beach is excellent for swimming, with climbers climbing right off the sand.
Pack water shoes for the rocky sections near the cave, reef-safe sunscreen and a dry bag for valuables if you swim, as Thai Holiday Guide advises. It also notes that there is no fresh water or shop directly on the beach, with the nearest small stalls back toward Railay village, so carry your own water and some baht. Wikivoyage warns that monkeys on the forest trails will snatch glasses, wallets or food, so do not feed them.
Climbing, the viewpoint and the lagoon trail
The cliffs behind the beach are a climbing area. Thai Holiday Guide says the routes run from easy 5a to 5b lines for a first try to steeper 6c to 7a+ pitches, and that Railay schools run half-day introductory sessions with harnesses, shoes and a guide. Wikivoyage says Railay has over 700 bolted routes, and warns that bolts near the sea can be corroded, so use a reputable school.
Do not mistake the viewpoint trail for a stroll. Wikivoyage says the climb to the viewpoint takes about 20 to 25 minutes plus another 10, that the path down to the hidden lagoon is steep, rocky and dangerous, and that the trip is not advisable in sandals, in poor shape or with a heavy pack. Many visitors skip the lagoon; the beach itself is the reason to come.
How our 4 Islands day includes it
Phra Nang Cave Beach is on the programme of our Krabi 4 Islands speedboat tour, from $35 per person, right after the speedboat leaves the pier at about 9:00 am; the tour then walks across the Tup and Chicken Island sandbar, snorkels over a reef and has lunch on Poda Island. The programme puts the beach before the busiest hours that Thai Holiday Guide describes, but the guide may change the order around tide and crowds.
Doing it yourself costs roughly 100 baht each way by longtail, plus your time. The tour adds the pickup, speedboat, guide, breakfast, picnic lunch and snorkel gear, and you pay the national park fee, 200 baht per adult and 100 per child, in cash at check-in. See our Poda Island guide, the Railay beach guide and the tour schedule.

- Wear water shoes for the rocks near the cave and a dry bag for valuables.
