Latvia is generally a very flat country of low-lying plains, largely covered by forest. There are some low hils in the west and far southeast. A few high hills are found to the east of Riga, with the highest point being the Gaizinkalns at 311.6 m (1,022 ft). Small lakes and swamps dot the countryside. Important rivers include the Daugava, Gauja, Lielupe, Venta and Salaca.
