       Lam Nam Kok National Park's topography is defined by tower karst mountains interspersed with narrow plains. The valley is in the north, while the area's south side is a low slope with a river basin in the center interspersed with channels. The mountain ranges in elevation from 500 to 1,720 meters above sea level with Doi Chang's summit being the highest , rising approximately 1,720 meters above sea level. Doi Yao, Doi Bo, Doi Chang, and Doi Pha Mup are the area's most significant summits.

           The Kok River is a significant river in the upper North that flows through the area's central lowlands. The river originates in Burma and flows through Thailand to Tha Ton Sub-district in Chiang Rai Province's Mae Ai District. The total distance between Tha Ton Sub-district and the National Park is approximately 85 kilometers from west to east, and numerous tributaries run through the area, including Mae Kon Creek, Mae Mon Creek, Ya Di Creek, Chom Phu Creek, San Creek, Mae Sai Creek, and Lao Ai Creek. All of these creeks eventually join to form a large river, and they flow in conjunction with the Lao and Mae Kok Rivers, which are the province's primary waterways.
