Trip Overview 

In past years, Cosmoledo has become known as perhaps the finest giant trevally destination in the world: a legendary fishery that is perfect for anglers searching for the ultimate saltwater flats destination. This is one of the most remote, off-the-grid trips that we offer – an out-island, expeditionary adventure best-suited for anglers looking for an experience that is far from ordinary. The atoll is fished while basing off of a live-aboard, mothership platform - an 85-foot catamaran that accommodates eight anglers per week. Since this is an incredibly remote location, it is worth stating that this is not a trip for everyone. That said, if you are looking to access one of the most incredibly pristine, untouched eco-systems in the world in a comfortable, safe and reliable manner, there is no better option.

Cosmoledo is located on the same general area as the world heritage site of Aldabra and in many respects resembles the famous island that is often referred to as the “Galapagos of the Indian Ocean.” Within the Cosmoledo fishery, Menai and Wizard Islands occupy the east and west points of the atoll, named after the two ships that explored the atoll on the Moresby Expedition in 1822. The atoll’s south island stands near the main entrance to the inner lagoon, while the second smaller entrance is just south of Menai Island. The northern islands are interspersed with numerous islets and banks, all of which are home to good numbers of large fish. The sheer numbers and variety of fish species found within the Cosmoledo fishery has amazed the fly fishing world for years, with anglers from across the globe making the trip to sample the ultimate saltwater fly fishing playground. After a closure of six years (re-opened only in 2015), the atoll has been rested and the fishing has rejuvenated itself exactly as you would expect an untouched ecosystem full of hungry giant trevally and other species would.

Live-Aboard Details
Beginning in November of 2016, all live-aboard weeks on Cosmoledo will be based off of the Lone Star - a 85-foot sailing catamaran with a 39-foot beam, which makes it one of the largest sailing catamarans in the Seychelles. This luxurious vessel was completely refitted in 2015 and features a host of facilities you wouldn’t normally expect on a remote, outbound trip to Cosmoledo Atoll. The Lone Star is extremely stable, spacious and more importantly has a 1.85-meter draft that allows her to anchor inside the calm, shallow waters of the Cosmoledo lagoon. She cruises at an average speed of 10 knots, making her the perfect platform when operating trips and cruising between Astove, Assumption and Cosmoledo Atolls. The Lone Star offers five private, en-suite guest cabins situated on either side of the main living and social area. All cabins and indoor areas are fully air conditioned, allowing guests a chance to relax in a comfortable environment after a long day of fishing the flats in the heat of the India Ocean. On the fore deck she is spacious and boasts two large "trampoline" and net areas as well as numerous sun loungers for relaxing while enjoying cocktails. The stern of the vessel has a covered outside dining area with a set of stairs (sugar scoops) leading down to the water. This feature also allows for a safe and comfortable transfer from the skiffs to the main vessel each morning and afternoon. 

The crew for each week consists of four Alphonse Fishing Co. guides as well as six Lone Star crew who cater to your every need. The chef prepares a mix of Creole and international food each afternoon and evening, incorporating fresh fish and seafood on a daily basis if requested. The Lone Star can accommodate up to eight (8) fly fishermen per trip in either twin or single cabins, making for an extremely comfortable experience. Additionally, even though the Seychelles waters are considered to be very safe these days, there will also be security personnel on board at all times as an added precaution.

Food and Beverages 

All meals are served in the lodge’s indoor dining salon or on the covered outer deck area. The ship’s galley prepares a mix of Creole and international food, with an emphasis on fresh fish and other seafood. All bottled water and soft drinks are included in the package, and the ship stocks plenty of local beer and imported wines for sale. If you want liquor or any other beverages, we recommend that you buy what you need at the duty free store in the airport in Mahe or en route.

Typical Length of Stay

All Cosmoledo trips are seven nights and include six and a half days of guided fishing. Because this is a fishery that can only be accessed by a charter flight that runs once a week, all packages are fixed at one week in length.

Non-Angling Activities and Options

The reason to make the trip to Cosmoledo is to fish. There is zero infrastructure on the atoll, and – aside from wading the flats, walking the beaches or snorkeling – very little for the non-angler to do.

Internet / Communications
There is no Wi-Fi or cell reception on Cosmoledo. The mothership is equipped with a satellite phone, which can be used in the case of emergencies. Guests that need the ability to communicate with the outside world while on Cosomoledo are encouraged to bring a sat phone.

Even though the Seychelles waters are considered to be safe, there will be security personal from the Seychelles Coast Guard and Vessel Protection Detachment on board at all times during the 2016 season as a precaution.


General Fishing Information
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 planet earth's GT headquarters! Geets are, however, not the only species which can be found throughout the Cosmoledo fishery in numbers. Bonefish, milkfish, the finicky Indo-Pacific permit and a host of triggerfish species all call Cosmoledo home and can easily be found throughout the fishing season.

This is primarily a wade-fishing destination, where each day three clients and one guide head out for a long day on the water. Clients carry their own waterproof backpack while wading the flats, along with both a bonefish and trigger rod (usually a 9 weight) and a heavier GT rod (usually an 11 or 12 weight). Each fishing day usually begins at 8:00 AM and runs late into the afternoon – usually 5:30 PM or slightly later. Tides play a huge role in which types of species are found throughout the day, and it is common to set up several different “sessions” in different locations for different species throughout the day (triggers and bonefish at low water, GT’s on the incoming tide, etc.) The guides know the area and the fishery well and will plan and execute each day according to tides and overall conditions.

Boats and Equipment
Anglers fishing Cosmoledo will utilize four Mini-Mahe tender boats, fishing two-to-a-skiff each day. Each tender will be skippered by experienced guide. As most of the fishing is done while wading on the flats, there will always be a ratio of two guests fishing with one guide. All of the Cosmoledo trips are led by a team of seasoned, experienced and professional fly fishing guides from Alphonse Fishing Company. During your stay on the vessel there will be four guides including one head guide onboard. Each guide is a qualified skipper, has first aid experience and is extremely experienced with regards all facets of fly fishing these remote atoll destinations. It is recommended that clients bring all gear, equipment, terminal tackle and flies with them. That said, the guides do sell flies on board the mothership, and we always recommend that you purchase whatever guide-tied "local" patterns that the guides recommend. Yellow Dog will be happy to help you pre-order these fly selections so that they are waiting for you when you arrive.


How To Get There
The primary airport and access hub for the Seychelles is the Mahe International Airport (SEZ). The Seychelles is served by several internationally scheduled flights, including direct services from London (Heathrow) with Air Seychelles, Paris with Air France, Dubai with Emirates, and Johannesburg with Air Seychelles. From the U.S. you will typically fly to Paris, London or Dubai, and from there fly directly to Mahe (SEZ). Each flight is approximately eight to 10 hours long. Guests should plan to arrive on Mahe the day before and overnight in order to catch the morning shuttle to Astove. Yellow Dog is happy to assist with hotel reservations or recommendations on Mahe.

Arrival and Departure Details / Times
Guests should plan to arrive on Mahe the day before the start of the trip and overnight. The transfer flight departs Mahe for Assumption early the following morning. Charter flight times can vary, so it is best to play it safe and come in the day before. The flight from Mahe to Assumption is just under three hours on board a private chartered Beechcraft 1900. Guests are met by the crew at the Assumption landing strip and then led on a five-minute walk to the bay, where the live aboard will be anchored. On the last evening the catamaran will cruise back to Assumption for where the charter flight will pick the group up the following morning. On your departure day from Mahe, you should plan your international flight to depart Mahe (SEZ) no earlier than 7:30 PM, which is not really a problem since most international flights depart between 9:00 PM and 11:00 PM.

Documents Required
All U.S. citizens are required to have a valid passport that does not expire within six (6) months of trips dates. Please be sure that your passport has at least two blank, unstamped pages remaining in back, and that it is not torn, delaminated, or damaged in any way. UK, US, EU and RSA passport holders do not require a visa for entering the country of the Seychelles for vacation purposes.

Luggage Weight Restrictions for Inter-Island Flights
Beginning in late 2014, Mason’s Travel (the third party on-ground "guest handlers” in Mahe) was instructed to enforce the 15 kilograms (33 pounds) main luggage / 5 kilograms (11 pounds) hand luggage rule for all passengers boarding the IDC aircrafts to Alphonse Island, Farquhar, Cosmoledo and Astove Atolls. Passengers that fail to comply with the restrictions will be instructed to unpack their overweight luggage and will have to leave the unpacked goods in Mahe at their expense. Please be aware that there is not an option to pay ‘overweight’ baggage fees, as the aircrafts can only carry so much cargo.
