The limestone hills are a sub-range of the Tenasserim Hills that arise at the shore of the Gulf of Thailand, with the highest elevation being Khao Krachom at 605 meters (1,985 ft). Between the hills are freshwater marshes. Several of these marshes were converted into shrimp farms, as only 35 km2 (14 sq mi; 22,000 rai) of the total 69 km2 (27 sq mi; 43,000 rai) of marshes are part of the national park. A portion, 18 km2 (6.9 sq mi; 11,000 rai), of these marshes are scheduled to be declared a Ramsar site.

Two white sand beaches are in the park, Hat Laem Sala and Hat Sam Phraya. Hat Laem Sala is 17 km from park headquarters and can be reached from the village Ban Pu either by boat or by climbing up and down over a hill for nearly 30 minutes.

The park is approximately 58 kilometers (36 mi) south of Hua Hin.

The origin of the name "Khao Sam Roi Yot" is undetermined. Local lore has it that it means "mountain with 300 peaks,"[2][5] or the range had been an island where 300 survivors from a sinking Chinese junk sought refuge, or the range was named after a local plant called sam roi yot.[3]

Phraya Nakhon CaveEdit

Khuha Kharuehat pavilion, Phraya Nakhon Cave

Phraya Nakhon Cave (ถ้ำพระยานคร) is about 500 meters (1,600 ft) from Laem Sala Beach, approximately 17 kilometers (11 mi) north of park headquarters. Visitors can go to the cave by renting a boat or by walking across Tian Mountain. After that, there is a climb up the mountain about 430 meters (1,410 ft) to reach Phraya Nakhon Cave. Its most famous early visitor was King Chulalongkorn.[3]

There is a water well at the foot of the mountain known as Phraya Nakhon Well. It is made of baked clay bricks in a trapezoidal shape.

Phraya Nakhon is a large cave which has a hole in the ceiling allowing sunlight to penetrate. At the top of the hole, there is a stone bridge known as "death bridge" because many wild animals have fallen to their deaths from it.

Khuha Kharuehat Pavilion (พระที่นั่งคูหาคฤหาสน์) is a historic site built for King Chulalongkorn's visit in 1890. At certain times during certain months, the sun will shine directly on it. The pavilion has since become the symbol of Prachuap Khiri Khan Province. Later kings also visited the cave, including King Vajiravudh and King Bhumibol Adulyadej.

Klong Khao DaengEdit

Klong Khao Daeng is a 4-kilometer-long (2.5 mi) stream running deep into mangrove forests at one end and at its mouth freshwater and seawater collide. The mangroves consist of the samae thalay (grey mangrove), kongkang bai lek (true mangrove), kongkang bai yai (red mangrove), and chakhram (herbaceous seepweed).[3]


The park is home to a variety of birds, including the common kingfisher, the black-capped kingfisher, the collared kingfisher, the little heron, the little egret, and the Javan pond-heron. Wildlife found in the mangroves includes pla teen ([mudskippers]), pu kam dab (fiddler crabs), ling samae (the crab-eating macaque), collared kingfisher (nok kin pieo), snapping shrimp (kung deed khan), mud creeper (hoi khika), and oysters (hoi nangrom).[3] Rare animals in the park include the mainland serow (Nemorhaedus sumatraensis), dusky langurs (Trachypithecus obscurus), fishing cats (Prionailurus viverrinus) (Thai: เสือปลา; RTGSsuea pla),[4] as well as many bird species. At sea, Irrawaddy dolphins (Orcaella brevirostris) are sometimes seen.[6]


Khao Sam Roi Yot was probably where King Mongkut hosted European guests on 18 August 1868 to observe a total solar eclipse. The king was interested in astronomy and had calculated the date and location of the eclipse himself. His calculations proved better—by about two seconds—than those of French astronomers, who acknowledged his accuracy. He contracted malaria, possibly during that event, and died on 1 October.

The national park was created on 28 June 1966.[7] It was enlarged on 1 April 1982.[8]


The discovery of 3,000 years old cave paintings was announced by archaeologists from the Fine Arts Office in May in 2020. Some of the depicted pictures are still visible and clear, while some paintings were damaged by limestone etching. According to archeologist Kannika Premjai, paintings describe humanlike figures with accessories on their bodies, hunting scenes with bow and arrow. Moreover, there is also an animal figure seems to be serow (a goat-like mammal found regionally) found among the drawings.[9]

Khao Sam Roi Yot legendsEdit

According to Thai folklore, the giant Mong Li and his wife lived on the west coast of the Gulf of Thailand. Each had independently promised their daughter to Chao Lai and the emperor of China. When the daughter was old enough to marry, both future husbands arrived on the same date. Mong Li then cut his daughter into two halves. Chao Lai turned himself into a hill, while the traditional fruit basket to be presented to a Buddhist monk was turned into the Khao Sam Roi Yot mountains.


The island of Ko Kho Ram on the other side of the gulf was the elephant and the ox cart with the wedding presents.[10] Nom Sao Island is the daughter's breasts. Ao Sam Roi Yot, Kho Ram Island and Nom Sao Island's silhouette, seen from certain angles, look like a person resting in the middle of the sea. There is a goddess shrine on Nom Sao Island that is a popular attraction.[11]

Other islands in the same area are Ko Sattakut, Ko Rawang, and Ko Rawing.
