Khao Sam Roi Yot is the first marine national park of Thailand located 60 kilometers in the south from Hua Hin. This national park includes a series of limestone hills along the Gulf of Thailand with highest one at 605m above the sea level and the other part of this park is a freshwater marsh.
The main attractions of the national park are Phraya Nakhon Cave with its iconic royal pavilion and huge chambers. Among, other unique and really worth visiting places you can find here Khao Daeng Viewpoint which is 157 m high what allows to enjoy the view of valley and mountains.
Then you can go to the Khao Daeng Canal and have a boat tour through mangrove forest which might take around an hour. But if you want to lie on the seashore you can choose Laem Sala Beach or Sam Phraya Beach, both of them have a campsite.
Bueng Bua Wood Boardwalk – this is an excursion around the Freshwater Marsh which is the biggest one in Thailand. You can find there lots of different flora and fauna representatives, especially different birds.
Aside from the famous Phraya Nakhon Cave, you can visit also Kaeo Cave and Sai Cave, they both consist of stalactites and stalagmites with a very rocky surface which makes a walk challenging sometimes.
In Khao Sam Roi Yot you may find a great diversity of wild nature representatives, 320 species in total. There are even dolphins and a few kinds of primates. If wildlife is your cup of tea, then you should visit this place.
