Khao Sam Roi Yot National Park

4.5(4,070 reviews)

Spanning 98 square kilometres along the Gulf of Thailand coast, Khao Sam Roi Yot National Park is a diverse marine national park renowned for its dramatic limestone hills, mangrove forests, freshwater marshes, and white sand beaches. Its centrepiece attraction is Phraya Nakhon Cave, a partially collapsed cavern where a royal pavilion sits beneath a natural skylight — a striking scene that draws visitors from across the region. A second cave, Sai Cave, sits along the route in and is well worth exploring as a quieter, less-crowded alternative. During lotus season, the park's wetlands bloom spectacularly, and boat rides offer a closer look at the landscape and birdlife. The park covers around 12 designated spots accessible under a single entry fee of 200 baht, making it excellent value for a full day of exploration. Visitors can walk mangrove boardwalks, take boat rides through the marshes, and hike up to the caves via a steep but manageable staircase trail. The atmosphere is natural and unhurried, though Phraya Nakhon Cave in particular draws significant foot traffic. The park opens daily from 08:00 to 16:30. Arriving early — ideally at 8am, starting at the ranger's office — allows visitors to cover the most ground before the midday heat sets in. The hike to Phraya Nakhon Cave is steep, so comfortable, closed-toe shoes are strongly recommended. For the best natural light inside the cave, mid to late morning is the ideal time to make the climb.

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

Definitely worth visiting, get there mid to late morning for the best sun view. The walk to the cave is fairly steep so I would recommend you do it in the morning when it is cooler and wear sensible shoes and clothes. Initially you can either boat or walk to the start of the climb to the cave, if you dont want 2 short but steep walks take the boat and then you will only have the one that leads to the cave.

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

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 Through Klook or GetYourGuide

These platforms offer instant confirmation, free cancellation on most activities, and prices that are often lower than walk-up rates. 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.
