Lek Beach

    The general terrain is that of mountains and steep mountains, such as Khao Lak, Khao Lam Ru, Khao Saeng Thong, Khao Mai Kaeo, and Khao Plai Bang To. The highest peak is about 1,077 meters above sea level and the area is the catchment area of major rivers in Phang-Nga Province, including the Takua Pa River and the Phang-Nga River. It also consists of canals and many smaller creeks. The location of the Khao Lak - Lam Ru National Park Headquarters is at the coast adjacent to the sea on the west side of the national park. It is located in a rocky beach ecosystem which is about 3 kilometers long and has a sandy beach.

    Khao Lak - Lam Ru National Park is located on the west coast of the Andaman Sea; therefore, it receives influence from the southwest monsoon and northeast monsoon, causing rain almost all year round. There are only two seasons; summer starts from January until April, and the rainy season starts from May until December. The best period for tourism is between late December and April each year.

        General forest conditions within the Khao Lak-Lam Ru National Park area consist of:

          The beach forest is a plant community that grows on the coast in sandy soil or the scattered rocks of the coastal area. Many of the plants are halophytes due to the influence of salt vapor from the sea. Plant species include Calophyllum inophyllum L., Terminalia catappa, Fish Poison Tree, Derris indica (Lamk.) Benn., Hernandia nymphaeifolia (Presl) Kubitzki, Thespesia populnea (L.) Sol. ex Corrê, Hibiscus tiliaceus, Cerbera odollam Gaertn., Casuarina equisetifolia, Guettarda speciosa L., and Acrostichum aureum L..

Most of the plant species found have short, crooked or bent trunks because of the strong winds at the coast. Shrub found include Scaevola taccada (Gaertn.) Roxb and the herbaceous plant Goat's Foot Creeper. In addition, the areas with scattered rocks or the sandy beach can host mangrove plant species which grow from seedlings brought by the sea current to the shore where they germinate, such as Avicennia marina (Forssk.) Vierh., Lumnitzera littorea (Jack) Voigt, Xylocarpus granatum Koenig, Combretum indicum (L.) DeFilipps, Bruguiera cylindrica (L.) Blume., Black Mangrove, Rhizophora apiculata Blume, Rhizophora mucronata Lam., Scyphiphora hydrophyllacea C. F. Gaertn. and Excoecaria agallocha L.

          Due to the forest's geography, climate, and vegetation composition, there is an abundance of plants, food, and water sources. As a result, it is the habitat of significant wildlife, including mammals such as Chamois, Tapir, Southern Chipmunk, Marmot, Hook Bear, Small Mongoose, leeches, and the Large White-Eared Bat as well as other types of bat
