It is located in Lam Kaen, Thung Maphrao, Thai Mueang, Bang Thong, and Na Toei Sub-district in Thai Mueang District, Phang-Nga Province. The national park areas are separated into two parts by Highway No. 4 with the first part being the Thai Mueang Beach area, which is on the Andaman Sea. The beach is about 13.6 km long, with the broadest part of the park measuring 1,600 meters and the narrowest point of about 350 meters. At the end of the beach is a cape called Laem Ao Kham (Khao Na Yak), and in the eastern area is a large brackish water canal is the Thung Maphrao Canal and the Hin Lat Canal, which have most of the freshwater flows from the Lampi Mountain range. It is a tropical rain forest, with complex mountain landscape along norht-south, which is called Lampi Mountain range consisting of Khao Khanim, Khao Lampi, Khao Ton Yan Sai, and Khao Lam Lang, with elevations of 40–100 meters above mean sea level until the higher mountain area in the middle of the national park. The highest peak is Khao Khanim, which is located on the north side of the area, with a height of 622 meters above mean sea level.

The Khao Lampi - Hat Thai Mueang National Park is a source of many rivers and streams, such as the Lampi Canal, Khanim Canal, Lam Lang Canal, Phlu Canal, Khamnueng Canal, Intha Nin Canal, and Bang Po Canal.

The lower ground plants include ferns, Calameae, and bamboo, and there is a rubber plantation around the boundary line.

Thai Mueang Beach covers an area of approximately 15 square kilometers, or 20% of the national park area.

      At the end of the beach is a cape called Khao Na Yak, and there is a large brackish water canal on the east side where freshwater flows down from the Lampi Mountain range through the Thung Maphrao Canal and Hin Lat Canal into the sea. The muddy area at the’ estuary is a mangrove swamp forest that includes plant species such as Rhizophora apiculate Lam., Rhizophora apiculate, Xylocarpus moluccensis (Lam.) M. Roem., Xylocarpus granatum Koenig, Sonneratia caseolaris (L.) Engl., Sonneratia alba J. Sm., Bruguiera pamviflora, Vigna unguiculata L., and Avicennia alba Bl  There are also the Nipa Forest and the beach area is the beach forest.

Casuarina equisetifolia L., Fish Poison Tree (Barringtonia asiatica (L.) Kurz), Terminalia catappa, Derris indica (Lamk.) Benn., Black Plum, Scaevola taccada (Gaertn.) Roxb., and Seashore crewpine.

In the middle of the Thai Mueang Beach area there is about 1,000 rai (1.6 square kilometers) of freshwater that is trapped during the rainy season.

The plant community is a swamp forest which has been disturbed until it turns into a Samet forest. in which the white melon (Melaleuca leucadendra) is a prominent plant.
