Cosmoledo is the ultimate Seychelles fly fishing experience. This remote atoll is accessed by live-aboard which will allow you to experience fly fishing for Giant Trevally at its absolute best.

This medium-sized atoll has a variety of fishing opportunities from flats wading, deep channels, reef flats and bluewater. The large tidal movements create an environment well suited to predatory fish like Giant and Bluefin Trevally and while the expansive sand and reef flats provide ideal Bonefish and Indo-Pacific Permit habitat.

A limited number of anglers get to fish Cosmoledo each year due to its remoteness and cost but if you are looking for the ultimate flats fishing experience this is it. While Giant Trevally are the main quarry for anglers visiting Cosmoledo, there is a huge variety of the usual flats and reef species if you can draw yourself away from the thrill of casting at GTs.

  • Season: October–November and February–April
  • World's premier Giant Trevally fishery
  • Bonefish, Giant Trevally, Indio Pacific Permit plus other flats and Bluewater species
  • Ideal for experienced anglers
  • Isolated, remote coral atoll
  • 12 anglers per week

Accommodation is aboard The Mayas Dugong which is an ex-research vessel and has been upgraded and modified into a mother-ship catering for long range fly fishing expeditions. The ship can accommodate up to twelve anglers, four guides and a crew of eight.

Accommodation is in seven spacious guest cabins located on the middle main or lower deck. Each room has twin-beds and private en-suite bathroom and shower room facilities. The ship also has a comfortable lounge and dining area. All cabins and the main accommodation aboard the vessel are air-conditioned and offer a comfortable environment to be in, ensuring a good night's sleep.

The mid-deck on the ship offers a spacious area to relax and enjoy the view from an elevated location. To the aft-deck there is a large swimming platform which also doubles up as a fishing platform.

Food and dining on board the vessel is a mix of local fresh fish and international food.

In the 2016-17 season, a new 45 foot Catamaran, the Lone Star, will be used for Cosmoledo live-aboard trips. There will be eight anglers per week, five en-suite cabins and four skiffs.

There is NO internet connection but the ship does have satellite phone in the event of an emergency.

Fishing in the Seychelles offers the opportunity to catch a number of different species such as Yellow Fin Tuna, Barracuda, Milkfish and Bonefish. However the one fish that stands out as the main attraction is the Giant Trevally and out here they reach immense sizes. Fish of up to one hundred and thirty pounds have been hooked and landed on fly rods. They will test you and your gear to the absolute limit of its capabilities. Anglers from all over the world are drawn to face this challenge.

The Mayas Dugong visits three main atolls during each trip, Assumption, Cosmoledo and Astove.

Access to Cosmoledo Atoll which is the largest of these atolls has until recently been closed due to piracy. Thankfully the operation is back up and running and the fishing is better than ever. Cosmoledo is regarded as one of the finest, if not the finest location, for saltwater flats and GT fishing in the world. The sheer size of the wadeable flats, diversity and numbers of fish are staggering in and around the atoll, the islands and outcrops, inlets, channels and sandbanks offer numerous opportunities to target large fish. Combined with some rare and unusual seabirds and turtles, all making this a very special location.

Astove is a smaller atoll and offers the chance to target some really huge GT's along with Permit and Bonefish. It also offers some of the best bluewater fishing in the Seychelles. Just outside the reef edge the ocean walls just drop away and is home to various species such as trophy-size Giant Trevally, Dogtooth Tuna and Yellowfin Tuna.

Assumption is usually the last atoll to be visited and offers beautiful beaches and surf. Guest can walk and wade along the beach taking shots at the large predators that patrol the reef and beach edge. Or, if you fancy a break, it is the perfect place to snorkel and explore the undersea world.

The Mayas Dugong has four tender boats that ferry one guide and three anglers to each atoll island. There are four guides including one head guide. All the guides are professional and experienced skippers and fishing guides with First-Aid experience. They all understand and know the waters around these atolls very well. They will go the extra mile to ensure you catch the fish of your dreams. Most of the fishing is walking and wading and the boats are used to access the shallow flats and occasionally chase down large fish.

A typical day starts after breakfast and you should be on the move around 8:00am if not earlier and look to finish around 4:00pm-ish. Lunch is usually taken as a packed option but you can return to the ship if you prefer.

We would advise all anglers to take their own gear and fishing equipment. Rods, reels, lines flies, good wading boots Polarized glasses and lots of sunscreen. Most of the fishing is walking and wading.
