About this Water

Turneffe Atoll off the coast of Belize is the largest atoll in the Western Hemisphere and one of the world's premier saltwater fly fishing destinations. The atoll's vast network of flats, channels, and lagoons supports resident bonefish, permit, and tarpon — the saltwater grand slam in a single watershed. The flats stretch for hours of boat time, ensuring un-pressured water even on busy weeks. Resident tarpon in the 30–80 pound class hold in channel mouths year-round; permit cruise the white sand flats throughout the system. Multiple lodges operate from the atoll itself, providing on-water access from sunrise.

Turneffe is the largest atoll in the Caribbean — its sheer size means anglers can fish a full week without seeing another boat — and one of the most accessible 'grand slam' destinations on Earth.
