Mountains account for 40% of Vietnam's land area, and tropical forests cover around 42%. Due to its considerable variety of elevation, Vietnam's climate varies dramatically from place to place. The northern part of Vietnam consists mostly of highlands and the Red River Delta. Phan Xi Pang, located in Lao Cai Province, is the highest mountain in Vietnam, standing 10,312 ft high. Southern Vietnam is divided into coastal lowlands, the mountains of the Annamite Range, and extensive forests.
