Guide to Visiting Phra Nang Beach & Cave in Railay, Krabi

A useful travel guide on how to get to Phra Nang Beach & cave in Railay, Thailand.

Phra Nang Cave Beach is a stunning white-sand beach surrounded by tall limestone cliffs on the tip of the Railay Peninsula, in Krabi on the southern coast of Thailand.

This truly is one of the best beaches in Thailand, with plenty of things to do such as rock climbing, kayaking, snorkeling, and exploring Princess Cave and the little-known Bat Cave.

In this guide, I’ll detail everything you need to know about Phra Nang Beach, from how to get here via a 10-15 minute longtail boat from Ao Nang or walking from Railay East Beach.

I also include a fun list of activities and some lesser-known spots that we found like Hidden Beach which is accessible from Phra Nang.

About Phra Nang Cave Beach in Krabi

Phra Nang Beach is a beautiful beach accessible only by boat or by walking the track from Railay East Beach.

Because you can only reach it by boat or on foot, the beach draws a steady stream of weddings and day-trippers, and it's still the busiest stretch of sand on the Railay Peninsula. You'll also see it written as Phranang Cave Beach, or Tham Phra Nang in Thai.

The beach is named after the Phra Nang Cave, which is located on the east side of the beach. This cave is considered a sacred site by the locals and is dedicated to a mythical sea princess, which is where the name "Princess Cave" comes from.

The beach is typically patrolled by lifeguards during the peak season. It features a small island just off its shores, named Ko Rang Nok, which is accessible by swimming, kayaking, or walking at low tide.

How to Get to Phra Nang Beach

Since Phra Nang Beach is located in Railay, you cannot drive here from other parts of the Krabi Province since there are no vehicle roads on this peninsula.

Below I'll detail two great options for how to get to Phra Nang Beach either on a day trip or via the longtail boats from Ao Nang or Ao Nam Mao Pier, Krabi. Ao Nam Mao is the cheaper of the two at 80 Thai Baht (US$2.50) per person, and it's the more reliable crossing in low season because the eastern side of the peninsula stays calmer.

Tip: Phra Nang Beach gets very busy starting at around 11:00 AM.

Option 2: Longtail Boat from Ao Nang Beach

If you want to stay at Railay, or just visit on an independent day trip, then the best option is to take a longtail boat from Ao Nang Beach or Ao Nam Mao Pier.

The boat ride from Ao Nang is the best option. This takes just 10-15 minutes and costs only 100 Thai Baht each way to West Railay Beach. These longtail boats are shared and you must wait until they fill up with at least eight passengers. They run 8:00 AM to 6:00 PM, and after that you'll pay roughly 50 Thai Baht (US$1.55) more per person or charter the whole boat. At low tide the Ao Nang boats sometimes shift up the coast to Nopparat Thara Pier, with a tuk-tuk transfer included.

If you want to get directly to Phra Nang from Ao Nang, you can pay an additional cost to the boat driver and he will take you there.

I've written a detailed guide on exactly how to get to the Railay Peninsula for more information.

9 Things to Do on Phra Nang Beach

Here are the nine things I'd actually spend time on at Phra Nang, in the order I'd do them across a full day.

1. Phra Nang Beach Cave (Princess Cave)

The most famous attraction at Phra Nang Beach is the Princess Cave, also known as Tham Phra Nang Nok in Thai, which translates as the outer Phra Nang cave. It sits at the east edge of the beach, near where you walk out from Railay East Beach, and it's free to enter with no gate and no ticket. Don't confuse it with Tham Phra Nang Nai, the inner cave better known as Diamond Cave, which is a separate cave back on the Railay East side.

One of the first things you'll notice is the large wooden phallic symbols and a shrine at the entrance of the cave. Local fishermen consider this a sacred site and believe that it is home to a mythical sea princess.

Legend has it that fishermen once used to make offerings to this Indian Princess Goddess at this beach cave in exchange for a bountiful catch.

Over time, the Phra Nang cave became a popular pilgrimage site and is now commonly visited by those seeking fertility, hence the small wooden penises and colorful votive offerings like flowers, incense, and snacks.

2. Dine at The Grotto, Rayavadee's Cave Restaurant

The Rayavadee Resort is one of the most amazing places to stay in southern Thailand. But, even if you can't afford this 5-star resort, you might be able to splurge on one evening dining at its famous Cave Restaurant.

This restaurant has been going viral on social media lately, with elegant tables set up inside a natural limestone cave, illuminated with soft lighting overlooking the crystal-clear waters of Phra Nang Beach.

The restaurant is called The Grotto, and it serves a mix of Thai food and international cuisine. Lunch runs 12:00 to 16:00 and dinner 18:00 to 22:00. Non-guests can book, but Rayavadee now takes reservations through its online TableCheck system only, so calling won't get you a table. The Twilight Dinner set menu has to be reserved before 18:00 the day before.

3. Relax & Swim on Phra Nang Beach

Of course, one of the best things to do on Phra Nang Beach is just to enjoy the white sand and shallow waters for swimming and relaxing.

The beach is quite long, meaning there's plenty of space to lie down. From the beach, you'll even have a clear view of Koh Poda in the distance.

4. Go Kayaking

With its calm, shallow water dropping into a deep blue and surrounded by amazing caves and limestone cliffs, Phra Nang is the perfect beach for kayaking.

You can rent kayaks, stand-up paddleboards and snorkel sets from the kiosk right on the beach. Budget 200 to 300 Thai Baht (US$6 to US$9) an hour for a kayak, and haggle politely if the beach is quiet.

Alternatively, you can rent a Kayak at Railay West Beach and paddle around the headland to Phra Nang.

5. Swim or Paddle to Ko Rang Nok (Ko Rang Beach)

Perhaps the most distinguishing feature of Phra Nang Beach is the towering Ko Rang Nok, a small island just a short distance from the shore.

The Island has a small beach known as Ko Rang Beach, directly facing Phra Nang, which is a small, secluded beach great for swimming and relaxing.

During low tide, you can even walk out to Ko Rang Nok. At high tide, the swim is very short and easy, especially in calm conditions. Alternatively, rent a kayak and paddle out!

6. Walk to the Hidden Beach at Phra Nang

Located among the forested area at the western edge of Phra Nang Beach is Hidden Beach.

The only way to get here is to wade through the crystal clear waters beneath the limestone cave. At low tide, this is very easy. But, during the high tide, you may need to get wet up to your chest.

This beach features a small area of soft sand, shaded by dense forest. Hidden Beach is quite small, accommodating perhaps 6 people at most. If you're looking for a quiet area away from the crowds, this is the ideal spot.

7. Go Rock Climbing Behind Phra Nang Beach

Railay Peninsula attracts rock climbers from all over the world for its amazing Thai limestone. One of the best climbing spots on the peninsula is just behind Phra Nang Beach, known as "Escher World".

You'll find this at the base of the cliff on the way to the Bat Cave (below).

This route is popular for beginner and intermediate climbers, with polished rock and safe, titanium anchor bolts.

8. The Phra Nang Bat Cave

While Phra Nang Cave Beach is named after and made famous for the Princess Cave, the Bat Cave truly is a much more impressive natural feature.

This huge opening is visible from the shores of Phra Nang and looks like a huge hole carved out of the karst tower on the western end of the beach.

To get here, you don't need any special equipment. It's just a short walk through the jungle on the western side of the beach, followed by a light, 10-meter scramble, then a walk up through the cave aided by rickety bamboo ladders.

The Bat Cave viewpoint is found at the end of a narrow tunnel, which squeezes out to a viewpoint area with panoramic views over Phra Nang Beach.

9. Go Snorkeling

Snorkeling is one of the best things to do in Railay, and Phra Nang has two areas where you can swim with fish and enjoy the healthy coral reef.

Both of these coral areas are found at either end of the beach, with the western end being a little healthier.

What to Expect on Phra Nang Beach: Facilities, Tides & Safety

Phra Nang has almost no infrastructure on the sand outside of Rayavadee, so plan on carrying what you need for the day. The nearest toilets sit back near the East Railay Viewpoint trailhead and cost 10 Thai Baht (US$0.30), paid in coins at the door, so keep small change on you.

One kiosk at the eastern end sells cold drinks and water and rents out kayaks and snorkel gear. Longtail food boats pull onto the sand through the middle of the day selling noodles, fruit and shakes, and that's the extent of the catering. There are no sun loungers or umbrellas for hire and very little natural shade at midday, so a towel and a hat do more work here than they do over at Railay West.

Tides change this beach more than the seasons do. At high water the eastern end near Princess Cave largely disappears and you can end up wading knee-deep around the rocks to get through. At low water the sand more than doubles, the walk out to Ko Rang Nok opens up, and Hidden Beach becomes a dry-footed stroll instead of a chest-deep wade. Check a Krabi tide table the night before and aim for the two hours either side of low tide.

One more thing worth knowing before you swim. In June 2026 Krabi authorities banned swimming at three national park beaches after Portuguese man o' war washed up: Laem Tanod on Ko Lanta, and Ao Ling and Sam Hat on Phi Phi Don. Phra Nang wasn't on that list, but red flags now go up across the province whenever they're spotted, so glance at the flag line before you get in. If someone does get stung, Thailand's tourism authority says to get them out of the water, keep them still, pour vinegar over the sting for at least 30 seconds, and call 1669.

Tips for Visiting Phra Nang Beach

I hope that you've enjoyed this travel guide to Phra Nang Beach at Railay in Krabi, Thailand. Before you go, here are some final tips to make sure you have a great time at this incredible cave beach.

• Peak season - the high season runs between November and April when the weather is dry and sunny, perfect for beach hopping. This is the best time to visit Railay. However, Krabi took 3.63 million foreign visitors in 2025, and most of them put Railay on the list. So you can expect some crowds at this popular beach.
• Visit early - if you're coming from Ao Nang I recommend taking the first longtail boat at 8:00 AM, or earlier if you're in a larger group and can fill the boat.
• Respect local customs - remember, the wooden penises are funny, but this is a sacred site for local people. Please respect the cave and beach.
• Watch out for monkeys - the walking track from Railay East Beach to Phra Nang Beach is a hotspot for monkeys. Be mindful and keep snacks away from them. Do not feed them as this can make the population aggressive.
• Take your trash with you - Thailand isn't exactly known for being very efficient with its trash management. Remember, Railay has no vehicle roads, so all trash is taken out via the long tail boats. Try your best to minimize your single-use plastic consumption, and take your trash with you from the beach.
