Arusha National Park is one of the few destinations in Tanzania where canoeing is possible. Take your pick between Momella Lake and Lake Duluti, which was left behind by erupted volcanoes. Birdlife is bright and plentiful, including elegant flamingoes and fish eagles, uproarious great kingfishers and hoards of cattle egrets who roost on islands at sunset. While canoeing on Momella Lake, keep your eyes peeled for buffalo, giraffe and snorting hippo.
