Below lies Lake Tanganyika, the second deepest lake in the world, with clear water and hundreds of fish species that occur nowhere else. After a hard morning in the mountains you can walk straight into the lake.
Gombe is small, and that means something. About 77 chimpanzees still live here, spread over three communities, which is almost half the 120 to 150 of the sixties.
There is hardly any other large game. No lions, no elephants, no Big Five, and there are no roads so no game drives either. A traveller summed it up bluntly, apart from the chimpanzees there is no other animal to speak of.
The terrain is steep and often slippery, and a trek takes one to three hours, sometimes longer. And the accommodation in the park is simple.
What you get back for it is a place where history was written, chimpanzees that have been used to people for generations, and a lake you can swim in at the end of the day.
