Cosmoledo, The Seychelles

In recent years, Cosmoledo has become known as the best giant trevally fishery in the world and has become the benchmark for fishermen searching for the ultimate saltwater flats destination.

The Cosmoledo trip is unique in the fact that rods get the opportunity to fish three atolls during their week, namely Cosmoledo, Astove and Assumption. Cosmoledo is a stone’s throw away from the world heritage site of Aldabra.

Cosmoledo’s large white sand flats, lagoon edges and channels are without question ruled by the notorious giant trevally. Bonefish, milkfish, the finicky Indian Ocean permit and a host of triggerfish species are all found at Cosmoledo.

Astove is a gem and fishermen get the chance to spend one or two days fishing this smaller atoll weather permitting. It is unique to the other outer atolls in that it has only one small channel linking the sea to the lagoon. This is one of the great areas to target the many large giant trevally. Astove has equally impressive fishing for bonefish, triggerfish and many other flats species.

Assumption is generally the final fishing option, as the mothership anchors in the calm lee of the island the night before guests are scheduled to fly back to Mahe. Rods have the option to spend their last morning either walking, snorkelling or fishing Assumption’s exceptionally beautiful beaches and surf zones, targeting some of the countless pelagic species which can be found just offshore.

Deep water begins very close to shore at Cosmoledo, Astove and Assumption and it is possible to fish from the tenders as well. Here the most common species encountered are giant trevally, barracuda, wahoo, yellowfin and dogtooth tuna, sailfish and the occasional striped marlin.

Four Mini-Mahe tender boats are skippered by experienced guides to access the fishing. As the fishing is predominantly done by wading there will be three guests fishing with one guide. All trips are led by a team of four world-class professional fly fishing guides including one head guide.


The Mayas Dugong is an ex-research vessel, which has been upgraded and modified into a mothership catering for long-range fly fishing expeditions.

She is rustic and can accommodate up to 12 fly fishermen, four guides, as well as eight crew and four security personnel who cater for your every need. A large, spacious and extremely stable vessel, she is the perfect base from which to explore the remote outer atolls of the Seychelles. Because of its large size and high fuel storage capacity, the Mayas Dugong can cover long distances at good speed and comfort in almost any sea conditions.

The Mayas Dugong is a four level vessel, which offers seven spacious guest cabins situated either on the middle, main or lower deck. Each has an ensuite shower and flushing toilet. The vessel also has a comfortable salon and dining area. All cabins and indoor dining or entertainment areas are fully air-conditioned. The chef prepares a mix of Creole and international food. Fresh fish can be served everyday if requested.
