Cosmoledo Atoll sits at the southern edge of the Seychelles outer islands and produces some of the best GT numbers on fly anywhere in the Indian Ocean. This is where serious GT anglers come — and for good reason. The flats deliver prolific shots at aggressive fish, while deeper drifts within the lagoon produce bigger GT. Beyond the GT fishing, Cosmoledo carries giant bonefish, occasional permit on the right tides, and solid triggerfish when conditions allow. But make no mistake — GT is why you come here. Everything else is a bonus.
