Although close to the equator, Rwanda has a temperate climate due to its high elevation, with the highest point being Mount Karisimbi. The terrain consists of mountains and gently rolling hills, with plains and swamps in the east. Abundant wildlife, including rare mountain gorillas, have led to a fast-growing tourism sector. Unlike many African countries, Rwanda is home to only one significant ethnic and linguistic group, the Banyarwanda. The country is well known for its native styles of dance, particularly the Intore dance, and for its drummers. Kinyarwanda and German are the official languages.
