The best beaches in Krabi are not all where the photos suggest. Along the mainland, Ao Nang, Nopparat Thara, Klong Muang and Tubkaek are reached by road. Railay, further down the coast, has no road at all: its four beaches are reached by boat, and they are not alike: Railay West is for a swim, Railay East not at all. The island beaches, such as Koh Poda and Bamboo Island, are stops on a boat day, not places you go on your own.
Three things then decide whether a beach is good on the day you are there: the tide, which empties some bays and uncovers sandbars at others; the southwest monsoon, which reaches this west-facing coast from May; and, in the rainy months, the jellyfish.

The short answer
For a swim, Railay West: sand between two walls of limestone, a short longtail ride from Ao Nang. If you would rather not take a boat at all, Klong Muang and Tubkaek, further west, are calmer than the town beach. And whatever the photos say, do not plan a swim at Railay East.
Pick your beach
-
The best swim within reach of Ao Nang
Railay West
By longtail from Ao Nang Beach; expect to step off the boat into shallow water.
-
Cliffs standing on the sand
Phra Nang
At the southern tip of Railay, on foot from Railay East; go early, before the island tours stop.
-
A calm beach by road, away from the boats
Tubkaek
Shallow, quiet water, few longtails and a view of the Hong Islands.
-
A long walk on the sand at low tide
Nopparat Thara
Next to Ao Nang, inside the national park, with a sandbar at low tide.
-
The beach not to plan a swim at
Railay East
Mangrove and mudflat at low tide: it is where boats land, not where people swim.
The mainland beaches
These four are reached by road from Ao Nang and Krabi Town. They run along the same stretch of coast, from the busy town beach to quiet resort beaches further west.
Ao Nang
The town beach · by road
A long curve of sand facing west, with a promenade of hotels and restaurants behind it and cliffs closing the view to the south, towards Railay. It is the boat station of the coast as much as a beach: longtails land and leave along part of it, and the middle stretch is the busiest and noisiest. The eastern end is described as calmer and shadier. The sand is golden, mixed with crushed shell, not powder white. Swim where others swim, away from the boat lanes. Not for you if you want a quiet beach by day.
Nopparat Thara
Next to Ao Nang · national park
The long beach just west of Ao Nang, about 2 km lined with casuarina trees, part of the Hat Noppharat Thara-Mu Ko Phi Phi National Park. At low tide the sea pulls back a long way and a sandbar runs out towards the islet offshore, walkable for a couple of hours around low water. The Nopparat Thara Pier is where most ferries and speedboats from Ao Nang leave for Phi Phi, Lanta and Phuket. Not for you if you want to swim at any hour: at low tide the water is a long walk away.
Klong Muang
Resort beach · west of Nopparat Thara
A calm stretch of coast with resort hotels, west of Nopparat Thara. At low tide the shore turns rocky, and swimming is better at high tide. Good for a stay built around the hotel; less so if you want to walk out to restaurants or boats. Not for you if you want a swim whatever the tide.
Tubkaek
The furthest west · calm water
A long, curving beach further west again, with calm, shallow water, few longtails, upscale hotels and a view across to the Hong Islands and Phang Nga Bay. The Dragon Crest trail (Khao Ngon Nak) starts from Tubkaek. Not for you if you want restaurants and boats within walking distance: it is a beach to stay on, not a town.
Railay: four beaches, no road
Railay is a peninsula cut off from the mainland by limestone cliffs, with no road: you arrive by boat. Longtails from Ao Nang land on Railay West, with no jetty, so you step down into the water. Boats from Ao Nam Mao and from Krabi Town land on Railay East, at a floating pontoon. The two sides are about five minutes apart on foot, and the beaches are very different.
Railay: getting there and what to know
Railay West
The swimming beach · by boat
The west-facing side of the peninsula: sand and clear water, with resorts set back behind the trees. This is the beach people mean when they say Railay. Go in the morning, before the day boats arrive. Not for you if you are carrying heavy luggage and dread a wet landing.
Phra Nang
Southern tip of Railay · free
The beach where the cliffs come closest, standing on the sand. A path at the foot of the cliffs leads here from the southern end of Railay East, in about ten minutes, or about fifteen from Railay West. At one end, a shallow cave holds the shrine to Phra Nang, with carved wooden phalluses left as offerings: it is a place of worship. Entry is free. Island tours stop here too, so come early. Not for you if you want it to yourself once the tour boats arrive.
Railay East
Mangrove side · no swimming
A shallow, muddy bay lined with mangrove, where the boats from Ao Nam Mao and Krabi Town come in. At low tide the water goes out and leaves a mudflat. It is not a swimming beach: people land here and walk across to Railay West. Not for you if you came for a swim, at any tide.
Tonsai
North of Railay West · climbers
The next bay north, the base of climbers and backpackers, more rustic than Railay and with a rockier shoreline than Railay West. At low tide you can scramble over the rocks at the northern end of Railay West, a slippery route with one boulder to climb; otherwise a steep jungle path takes about twenty minutes. Not for you if you would carry luggage over the rocks, or take the path in the rain or after dark.
Island beaches
The beaches on the islands are reached on an island day or a private longtail, not on your own. They are inside a national park, and the entry fee is usually paid in cash on the day, on top of the tour price. Not every famous beach is for swimming: at Maya Bay, on Phi Phi, swimming is not allowed.
Krabi islands: which day, which boat
Koh Poda
Four islands · the beach landing
On the four-island day, Koh Poda is usually the stop where the boat puts you on the sand. Expect it to be shared with many boats on the same route. Sources disagree on the park fee for this group of islands, so check at booking whether it is included and keep the ticket on you. Some Phi Phi days from Krabi finish here for sunset. Not for you if you want an empty beach.

Chicken Island and Koh Tup
Four islands · the sandbar
Chicken Island (Koh Kai) is mostly seen from the boat, with a snorkelling stop. At low tide a sandbar appears between Koh Tup, Chicken Island and Koh Mor, and you can walk along it; at high tide it is under water. The tide changes every day and no operator can promise it. Not for you if the sandbar is the point and you cannot check a tide table for your date.
Bamboo Island
North of Phi Phi Don · some Phi Phi days
A separate island north of Koh Phi Phi Don, added to the route by some Phi Phi tours from Krabi. It has no annual closure in the park's list, unlike Maya Bay. The park charges its Phi Phi rate here: 400 baht per foreign adult, 200 baht per foreign child, as of October 2026. Not every Phi Phi tour stops: check the list of stops. Not for you if you want a short day: it comes with the long crossing to Phi Phi.

Koh Lanta
Long Beach, Koh Lanta
Hat Phra Ae · west coast of the island
Long Beach, Hat Phra Ae in Thai, is on the west coast of Koh Lanta. Lanta is a separate trip rather than a beach day from Ao Nang: by road it takes about three hours from Ao Nang, by van and a vehicle ferry, all year; boats run mostly from November to April. Not for you if you want a day trip from Ao Nang: it is a stay in itself.
The tide
The tide changes Krabi's beaches more than anything else, and its times move every day. Look at a tide table for your dates before you plan a beach day around one place.
Railay East. A mudflat at low tide. It is never a swimming beach, and at low tide it is not even a wet one.
Nopparat Thara. The sea pulls back a long way and a sandbar runs out towards the islet offshore: the time for a walk, not a swim.
Klong Muang. Rocky at low tide; the swim is better when the tide is in.
Ao Nang. At low tide the water recedes, and you walk across wet sand or wade out to reach your boat.
Koh Tup. The sandbar to Chicken Island and Koh Mor appears only at low tide.
Tonsai. The route over the rocks from Railay West works at low tide only; at high tide, take the path.
Jellyfish and red flags
Box jellyfish are found off this coast, and they come closer to shore during the monsoon, when the wind and currents push them in. The Tourism Authority of Thailand names Koh Lanta and the Hat Noppharat Thara-Mu Ko Phi Phi park, which includes Nopparat Thara and Phi Phi, among the places where they are seen.
If you are stung, pour vinegar on the sting for at least 30 seconds; never fresh water or alcohol. Call 1669 for an ambulance. Hotels, beach restaurants and dive clubs are required to keep vinegar, but it is worth carrying your own.
In wind and swell, the national park raises red flags on the beaches. A red flag means swimming is dangerous, and rip currents are common in the monsoon: stay out of the water when one is up, whatever other swimmers do.
On and around Koh Lanta, Thai press reported in June 2026 that Laem Tanod, Koh Haa and Koh Ngai were closed because of Portuguese man o' war, with no confirmed reopening date. Check before you go.
The sea season
Krabi's coast faces west, onto the Andaman Sea, and that is the side the southwest monsoon arrives from. It brings the rains from about May to October; in 2026 the rainy season officially began on 15 May. In the official averages for Krabi (1981–2010), October is the wettest month, followed by September and August, and January the driest.
In the monsoon the Andaman can raise waves of 2–3 metres, and on some days the Krabi harbour authority stops boats from going out. The longtails from Ao Nang to Railay can be suspended when the sea is rough; the boats from Ao Nam Mao to Railay East, on the sheltered side, are described as the more reliable crossing then. Island tours keep running, but any departure can be cancelled, and the boats to Koh Lanta run mostly from November to April.
For a beach holiday built around swimming, the dry months, from about November to April, are the safer bet. In the rainy season, the beaches are still there; the swim depends on the day.
Sunset
Ao Nang and Railay West both face west, so the sun goes down on the sea side. At Ao Nang, the late afternoon is the time for the light on the cliffs.
If you watch it from Railay and sleep in Ao Nang, think about the way back first. The shared longtails run from about 8 am to 6 pm, leaving when the boat is full, and sources disagree on what happens after that: a shared boat at a higher fare, or only a whole boat to hire. Some Phi Phi tours from Krabi end the day at Koh Poda for sunset instead.
