Karanambu, a 100-square mile former cattle ranch, is the home of Diane McTurk, a world-renowned expert on giant otters. Located in the North Rupununi, a region of southwestern Guyana known for its expansive wetlands and savanna, as well as its biological and cultural diversity. There may be as many as 700 species of fish at Karanambu — more than anywhere on Earth. Village neighbors include the Makushi villages of Kwaimatta, Massara, Yupukari, Toka, and Simoni. Though remote, Karanambu is increasingly popular as an ecotourist destination. Visitors stay at the award-winning Karanambu Lodge. The Karanambu Trust is active in conservation, research, training, and sustainable development.
