Namchi district lies at an altitude of 400 to 2000 metres and has a temperate climate for most of the year. Major urban centres include Namchi, Ravangla, Jorethang and Melli.
South Sikkim is the most industrialised district in the state, owing to the availability of flat land. Since the geology is stable the roads are in good condition as compared to other parts of the state which suffer from landslides. The district is also known for Sikkim tea, which is grown near Namchi.
