Mabaruma is the administrative centre of the Barima-Waini region in northwestern Guyana, sitting close to the Venezuelan border. It is a remote town reachable only by small aircraft from Georgetown or by a long boat journey upriver. The surrounding area includes mangrove-lined coast, rivers, and forest that is part of the range of the harpy eagle — Guyana's national bird.
Mabaruma is the closest access point for Shell Beach, the protected Atlantic coastline that is one of the Caribbean's most important sea turtle nesting sites. Leatherback, hawksbill, green, and olive ridley turtles nest here between March and August. Getting to Shell Beach from Mabaruma requires a multi-hour boat journey through mangrove creeks, typically arranged through a local guide or a Georgetown-based tour operator. There are no facilities on the beach; visitors camp and patrol the sand at night with rangers.
The community of Hosororo, a few miles outside town on the Aruka River, is worth visiting for river wildlife and to get a sense of Warao river culture. Mabaruma Airport is the only practical way in and out — Trans Guyana Airways connects the town to Georgetown's Ogle Airport in under an hour.
The town itself is small and has few facilities for travellers beyond basic accommodation and food. Go for the wildlife, not the amenities.
