Khao Sam Roi Yot National Park

4.6(4,243 reviews)

Come for Phraya Nakhon Cave, the collapsed cavern with a royal pavilion sitting under a natural skylight, and accept that everyone else is coming for the same thing. Mid to late morning is when the light drops through the hole in the roof and does what you've seen in the photos. Getting there means a steep climb, mostly stairs, either after a short walk or a boat ride round to the beach. Take the boat if you'd rather do one climb than two, and bring sandals, because you wade a little to get aboard.

Don't skip Sai Cave on the way in. It's a short steep push, maybe twenty minutes up, and far quieter. Beyond the caves the park runs to limestone hills, mangrove boardwalks, freshwater marshes and beaches across 98 square kilometres, with 12 marked spots covered by the single 200 baht entry fee. Lotus season is worth timing for, and there are boat rides through the wetlands.

This is definitely worth checking out while you’re in Hua Hin! It’s a bit of a “hike” (I used quotes because it’s mostly stairs 🤷‍♂️), but totally worth it, but here a a couple of things to know before you go. First, you have a choice of walking/hiking there or taking a boat. I took the boat cause I wanted to be on the water, beach is so beautiful here. If you take the boat, bring sandals because you must walk into the ocean a bit to climb onto the boat. If you walk, it looks like an equally beautiful walk; the natural landscape here is beautiful. One last tip: while in line, a local asked us if I wanted to split the cost of the boat with her and her daughter. I agreed (if I recall correctly, paid 200 of the 400 TBH total), and this is an important point. This very cool and nice local girl informed me that she was happy I agreed because she claimed that the people operating the boat-ride service will often try to add a lil foreigner tax if you’re not in the “know.” She told me that they will usually tell foreigners that it is 400 TBH per person, when the actual cost is 400 TBH total for the ride, which can be split amongst the passengers in anyway they see fit. Ergo, according to this cool local girl I was fortunate enough met there, if they tell you that it’s 400 per passenger, it’s definitely a foreigner tax haha 🤣. Back to the “hike”, I wore sandals to get on the boat and for the hike, and I was totally fine. I’m not the Michael Phelps of hiking nor anything like that 😝 , just saying that if you’re concerned, might wanna bring a towel and a pair of shoes to change into after the boat ride. Like I mentioned earlier, it’s mostly stairs you’re climbing, but they are stairs carved out of rock or made of wooden logs, you know like almost kinda like “natural” stairs, not something built from Home Depot supplies. The “stairs” are often uneven, slippery, jagged, etc., but I did it in sandals and I’m a 40+ yr old dood, so…. It is not the shortest “hike” haha and it can get hot af, so bring water. Once you get to the end, totally worth it tho. There’s a couple of fake/statue monks on display in the cave so don’t let those freak you out haha 😂. But yeah fr tho, totally worth it. Once you’re back to the beach the boat dropped you off at, there’s a really good local restaurant there selling some delicious, grub food there. So after the “hike”, grab some good local eats and a fresh coconut water 😋. One last thing, when we first arrived, I was instructed to remember the number of the boat that dropped me off, which I did, but didn’t seem to matter later 🤷‍♂️ but might be a good idea to jot it down somewhere for Justin (just in case lol). Enjoy your trip. @CBD-travelchannel

Great place to visit it’s a full day doing the 12 spots that are available to visit under the 200 BTH park entry fee plus parking Best way is to start at 8 am at the ranges office and mangrove walkway It’s a physical day with some fairly deep cave exploring bring a torch and stay hydrated and have a lovely sunset at spot 12 kissing

Highlight in the region Great caves to see The super touristy one is Phraya Nakhon, you must see it for sure However there is Sai Cave on your way in and it’s definitely worth a stop Sai is 20’ up, steep path Nakhon is up / down to a beach then up / down to the cave. Go & back & visit I’d say 2 hours with a good still easy pace. It took me 1 total but I run 😁 Entry 200B as usual Caves access closes at 1530 Maps, GMaps pins and schedule attached

Tips for Visiting Activities & Tours

Vet Elephant Sanctuaries

Only visit sanctuaries that prohibit riding, use no chains or bullhooks, and let elephants roam freely. Elephant Nature Park in Chiang Mai set the standard. If a place offers painting shows or circus tricks, walk away.

Book Popular Activities Online

Booking platforms like GetYourGuide give you instant confirmation and, on many activities, free cancellation — and you can read recent reviews before committing. Compare with local agencies for multi-day trips where negotiation might save more.

Do Outdoor Activities in the Morning

Heat and humidity peak from noon to 3 PM. Schedule jungle treks, cycling tours, and outdoor cooking classes for early morning. Water activities are more flexible since you're in and out of the sea.
