Climate The park is influenced by tropical monsoon winds resulting in two seasons: the first is a rainy season from May–December and a hot season from January–April. Average temperature ranges from 17-37 degrees Celsius. Average rainfall per year is about 2,231 millimeters, highest in July and lowest in February.
Wildlife The park has been designated an
Important Bird Area (IBA) by
BirdLife International because it supports significant populations of
pale-capped pigeons and
Christmas Island frigatebirds.
Fossil Shell Beach Susan Hoi Chet-sib Ha Lan Pee "The 75-Million-Year-Old Shell Cemetery" is located at Ban Laem Pho, which is part of the national park area. The
fossil site stretches along the seashore for about 2 kilometers from west to east. The formation consists of layers of limestone slabs with a thickness ranging from 0.5 to 1 meter. Each limestone slab contains a large number of fossilized
gastropods, mainly
freshwater snails of the genus
Viviparus, dating back to the
Tertiary period more than 70 million years ago. These shells accumulated in enormous quantities and were later cemented together by calcium carbonate, forming solid rock layers. The slabs are stacked on top of one another in successive layers, resembling a broad concrete pavement. The fossil shells are clearly visible on both the upper surfaces and the sides of the limestone slabs. The limestone layers slope gently from the shoreline toward the land at an angle of about 10 degrees, creating a wide exposed rocky platform. As a result, the coastline here appears as a rocky terrace beach rather than a sandy beach. This site is considered one of the very few shell fossil cemeteries of its kind in the world. ==Visitors==
