Cosmoledo's large white sand flats, lagoon edges and channels are, without question, ruled by the notorious giant trevally, so much so that it is often referred to as the GT capital of the world.

Trip Overview

Cosmoledo Atoll is situated a stone's throw away from the world heritage site of Aldabra, which is often referred to as the Galapagos
of the Indian Ocean.
Cosmoledo comprises of a larger white sand lagoon surrounded by 18 islands, numerous flats and two main channels. It is one of the most remote inhabited islands in the Seychelles, and can accommodate up to 10 fly fishermen per trip.
It's an untouched ecosystem full of hungry, tackle-busting giant trevally. Cosmoledo's large white sand flats, lagoon edges and channels are, without question, ruled by the notorious giant trevally, so much so that it is often referred to as the GT capital of the world. These fish are, however, not the only species that can be found here in impressive numbers. Large bonefish, bluefin trevally, bohar snapper, barracuda, milkfish, the finicky Indo-Pacific permit and a host of triggerfish species all call Cosmoledo home.


The charter flight will depart Mahé and after 3 hours will arrive to Astove island, where the team will be transported on a vessel to Cosmoledo Atoll. During the trip, anglers will be briefed about the fishing and the area as well. Upon arrival anglers will be accommodated in their rooms and get their tackle ready.

A typical fishing day goes as following:
Breakfast is served at 7.00 hs and anglers are ready to leave the lodge at 08.00 hs. Anglers can choose between a packed lunch or return to the lodge for lunch. Teams will head back to the lodge around 17.00 hs.
Dinner is served at 19.30 hs.

Fishing report

December 2022

A fun-filled second week here on Cosmoledo Atoll, with a very active bunch of returning guests. The week started off with multiple surf walks and ended with some very big GTs being seen once the neap tides arrived. The weather also played its part with the wind dropping off and sunny skies.

On the GT front, the size of the fish was well above average at around 90 cm, with Saif Al Zarouni catching the fish of the week measuring a lovely 96 cm. Saif also managed a second giant trevally of 90 cm on the last day. Ed Lawrence arrived with the hope of getting vengeance on a GT lost a few years back, and he won his battle on the first day and one-upped himself by catching a second lovely fish of 88 cm. David De Kock and Bill Kinney also managed to land their personal best GTs this week with David’s measuring 76 cm and Bill’s at 93 cm.

The triggerfish were also out and about this week with a good few seen and three lovely fish landed. Matt Born caught his personal best moustache trigger measuring a whooping 53 cm, while John Kinney landed his first moustache triggerfish. Saif also managed to land his first yellow margin triggerfish and a healthy one at that measuring 49 cm.

A good few bonefish were landed this week with David Ohara taking the ‘Bonefish King of the Week’ title by catching five extra-large Cosmoledo bones. Matt and David De Kock took the ‘Miscellaneous Fish of the Week’ award catching a massive African marble grouper and saddleback grouper on the flats. John Kinney kept his slam streak going from Alphonse and managed to land himself another awesome flats slam consisting of a GT, bonefish and triggerfish.

An awesome second week here on Cosmoledo with a lovely bunch of guests and familiar faces, although the fishing was tougher than usual a great week was had by all.

Stay tuned for next week’s report.

Tight lines!
