Enquire about this journey

The Simuni river is a tributary of the Rupununi, and finds it’s source high in the Kanaku mountains. Once the river winds down the mountains and forest, it slows down in the savannahs and opens up into 5 shallow river bays known as the Simuni Lakes. This area and these lakes are incredibly rich in biodiversity and are traditional breeding grounds for several species of game fish including: Butterfly Peacock Bass, Arawana, Arapaima, Payara, Piranha, and Catfish. The lakes are famous to local Guyanese fishers past and present and have always had a reputation for providing big fish and bigger fish stories.

Besides the excellent fishing, there is always a chance for great wildlife sightings including Squirrel, Howler, Capuchin and Bearded Saki monkeys. More impressive are the large Black Caiman that patrol the banks (they can grow to over 15 feet!), along with Giant River Otters and Capybaras. Riverine birdlife is extremely diverse, and include Jabiru Storks, Roseate Spoonbills, Woodstorks, Blackskimmers, Boatbilled Herons, and Muscovy ducks.

This trip is offered in the dry season only from October to April.

The cattle and the old ranch house are still there, but the ranch is now more renowned for Diane’s work rehabilitating Giant River Otters. Have family style lunch and then head to the Rupununi River. Twenty minutes later, you meet the Simuni creek and the famous Simuni lakes. Fish in the afternoon.
