Conservation and Significance

Both lakes are part of the East African Rift freshwater corridor, a UNESCO biodiversity priority. They face threats from overfishing but are protected by community partners and the Tanzanian government through lake-cleaning projects.

Best Pairings:

Combine the lakes with a chimp trekking experience at Mahale or Gombe, or transition to the alpine flora of the Kitulo Plateau for a complete Southern Circuit journey.
