am Roi Yot - Three Gulfs - a geographical

Gulf of Thailand

“Sam Roi Yot” is the first national park close to the sea. There is a huge and very high limestone mountain overlooking the large fresh water pond
on the west of this mountain. Sam Roi Yot stood out very clearly and could be seen from both the sea and land. Also, there was a big fresh water pond.
Paintings were found inside the caves here. They were painted in 1,800 - 4,000 years ago. This artifact showed traces of long settlement well before recorded
history. The name “Sam Roi Yot” has existed since before the Ayutthaya Period. In the reign of King Rama V, a royal pavilion called “Khuhakaruehat” was
built near this place, where some lofty old trees have naturally grown. Images from the satellite show that this geographical environment and coastal shapes
have changed many times in response to the sea level changes. The curved sea and several oyster lines around this limestone mountain and in the cave
are evidence.
“Three Gulfs” consist of the lining-up of three different seashores: “Ao Noi”, “Ao Prachuap” or “Koh Lak” and “Ao Manao”. They were administrated
by Muang District of Prachuap Khiri Khan Province. Its geographical shape was the result of the seashore which was once situated inside the main land.
Some limestone mountains line up in the sea near the shore. As time went by, sediments piled up and formed a “cuspate bar” and “tombolo” sticking out
into the sea. These three different areas were at the origin of the term “Three Gulfs” where Prachuap Khiri Khan Gulf was in the middle. Between the sand
dunes, was the “Tamonglai” mountain, which was situated at the tip of the Northern Cape. The mountain called “Lom Muak” was on the southern cape tip
where Koh Lak was located. “Koh Lak” was a place to mark the sea level standard.
