The mountainous region runs on a north-south axis and is comprised of a complex mountain landscape, with small and large mountains interspersed throughout. Elevations are between  400 -- 900 meters above sea level, with the highest summit known as Doi Farang (and previously Doi Ngam), which is 904 meters above sea level.
The area designated as Khelang Banpot National Park was originally created by sediment deposition of rivers and by the residual surface area left over from the erosion of shale, sandstone, gravel, and limestone. The undulating regions up and condition of terrain in this mountain range. Historical erosion has alsocreated dirt and soil, although in mountainous areas it i a slightly gravelly loam A small amount of soil series found: Wang Hai soil series, Mae Mok soil series, Mae Ngao soil series, etc.

The months with the highest and lowest monthly mean temperatures in Khelang Banphot National Park were April and January, with 37.8 and 14.4 degrees Celsius, respectively. It rains for on average 111 days year, with July having the most rainfallwith 17 days. The averageannual rainfall total is 1,060 millimeters, with September the wettest month with 213.3 millimeters.
     The climate is classified into three distinct seasons.
     Summer lasts from late February to early May.
     June to September is the rainy season.
     Winter begins in October and lasts until early February.

      Forest Resources - The area is primarily covered by deciduous dipterocarp forest alternates with mixed deciduous forest and pine forests, sporadic pine forests on the mountain summit, which is 700 meters above  sea level.
The different forests contain different species as trees, as follows:
      1) Coniferous Forest (Pine forests): Significant wood species include Merkus Pine (Pinus merkusii Jungh & De Vriese) and Dipterocarpus obtusifolius occurs sporadically where the ground is bare forest. Fruit is not common on the predominantly rocky terrain.
    2) Deciduous dipterocarp forest, the main species are Burma Sal (Shorea obtusa), Burmese Sal (Shorea siamensis), Hairy Keruing (Diptrocarpus obtusifolius), Diptrocarpus tuberoulatus, Buchanania latifolia, Cratoylum spp, Gardeia app, Vitex peduncolari, and Mitragyna brunonis, Groundcover plants include Kaempferia spp, Phoenix acaulis, and Cycad (Cycadales).
      3) Mixed deciduous forest includes  essential species such as Teak (Tectona Grandis), Burma Padauk (Pterocarpus macrocarpus), Black Rosewood (Afzelia xylocarpa), Gamari (Gmelina arborea), Beleric Myrobalan (Terminalia bellerica), Anogeissus acuminate, Millettia bandisiana, Kratie Rosewood (Dalbergia nigresoens) and many different types of bamboo such as Dendrocalamus striotus, Bambusa natans, Gigantochola albociliata, and Tinwa Bamboo (Cephalostachyum pergacile).
 

      As the area is mountainous there is abundant wildlife in the dense forests. The forest is fertile, provides habitat for small wild animals, and serves as a haven for them. According to a survey conducted  the forest contains the following animals:

      1) Ten species of mammals are found in this group including Leopard (Prionailurus bengalensis), Common Palm Civet (Priondpm erdocppr), Kloss's Mole (Euroscaptor klossi), Burmese Hare (Lepus peguensis), Wild Boar (Sus scrofa), Callosciurus caniceps , Chipmunk (Tupaia glis), Mongoose (Herpestes javanicus), and Bamboo Rat (Cannomus bedius).

      2) Birds are common in the park, with 11 species in 9 families. They include Red Junglefowl (Gallus gullus), Red-Whiskered Bulbul (Pycmonotus jocosus), White-Rumped Shama (Copsychus malabaricus) Common Iora (Aegithina tiphia), Scarlet-Backed Flower Pecker (Dicaeum cruentatum), Greater Racket-Tailed Drongo (Dicrurus paradiseus), Lesser Racket-Tailed Drongo (Dicrurus remifer), Black Drongo (Dicrurus macrocercus), White-Faced Jay (Garrulus glandarius), Chinese Pond Heron (Ardeola bacchus), and Common Myna (Acridotheres tristis).

         3) Amphibian wildlife includes 6 species in 4 families such as the Asiatic Burrowing Frog (Kaloula pulchra), Frog (Rana pilcata), Green Frog (Occidozyga lima), toads, Elongated Tortoise (Indotestudo clongata), and turtles.

           4) Reptile wildlife includes 4 species in 3 families such as the Butterfiy lizards, lizards, Eastern Bent-Toed Gecko (Cyrtodactylus spp.), and Waterfall Dwelling Snake (Elaphe taeniura).

        5) Four types of fish were found including the Dwarf Snakehead, Mastacembelus armatus , Dwarf Snakehead, Eel Garden, and Minnow.

        6) Thirteen species ofinsects were found in the National Park area including Cheirotonus parryi, Violin Beetle (Mormolyce), Common Bluebottle butterfly (Graphium sarpedon), Green Drgontail butterfly (Lamproptera meges), Common Birdwing butterfly (Troides helena), and the Common Rose butterfly (Pachliopta aristolochiae).
