target species

World Class

Giant trevally

The defining species on Cosmoledo. Prolific numbers of quality fish following rays and sharks across white sand flats — the ultimate GT sight fishing experience.

Excellent

Bonefish

Well above average size for the Seychelles. Present in good numbers across the atoll's extensive sand flats throughout the season.

Excellent

Triggerfish

Solid numbers across the atoll with consistent daily opportunities. A welcome change of pace from the GT fishing that defines Cosmoledo.

Good

Milkfish

Available during the season with good opportunities on the right tides. A genuine bonus species on an atoll that already delivers on every other front.

Good

Permit

Present throughout the season in above average size. Technical and demanding — but the atoll's low fishing pressure means fish that haven't seen many flies.

the destination

Cosmoledo Atoll is the GT capital of the world - and it earns that title through sheer numbers. While the atoll does produce fish over the metre mark, Cosmoledo is truly defined by its prolific populations of 60–70cm GT following large stingrays and sharks across pearly white sand. Pure sight fishing at its finest. Twenty-one tiny islands sit on the outer edges of this ancient coral structure, with miles of open sand and grass flats stretching between the surf zone and a complex lagoon system fed by two major tidal channels. Beyond the GT fishing, Cosmoledo carries well above average bonefish, solid Indo-Pacific permit, and reliable triggerfish - plus one of the most diverse seabird breeding sites in the Seychelles. The lodge experience is unlike anything else in the outer islands - eight converted shipping containers serving as luxury guest rooms, tucked into dense island shrubbery surrounding the central dining area and bar. Remote, intimate, and completely one of a kind.

guide's verdict

"Cosmoledo is the destination I'd send any angler chasing their first GT on a fly rod. The numbers here are extraordinary — fish following rays across white sand in crystal clear water. But what stays with you is the place itself. Twenty-one tiny islands, one of the most remarkable bird colonies in the Seychelles, and a lodge built from shipping containers hidden in the bush. There is genuinely nowhere else like it."
