on the Osa Peninsula and the Northern Coast


Costa Rica is home to an amazing range of fish species. Two oceans and a variety of rivers and lakes gives the fly fisher the ability to target many different species all within a relatively small geographic space. Our base of operations on Costa Rica’s Pacific coast is the Osa Peninsula. Touted to be ‘one of the most biologically intense places on earth’ by National Geographic, the Osa Peninsula (Osa for short) represents spectacular adventure across its many pristine terrestrial and aquatic habitats. Jaguars and tapirs still haunt the jungle covered mountaintops, and screeching scarlet macaws and toucans are a common sight as they move through the forest canopy.


Osa also offers some of the finest inshore and offshore fishing in the world, with inshore species including giant roosterfish, snappers, groupers, jacks, and snook, and offshore waters offering shots at some of the world’s largest Pacific sailfish, blue marlin, mahi-mahi, wahoo, and yellowfin tuna.


The Osa Peninsula is also host to an array of incredible surf casting locations, and plug and/or fly fishing shots at roosters, snook, jacks and other large predators from terra firma abound. Combine a few days on the sand or rocks with your bluewater & inshore adventure, or focus on this challenging but stunningly beautiful fishery on its own.


Fishing is generally incredible year-round, but noteworthy spikes in pelagic migrations take place December - April. Coinciding with Costa Rica's dry season (or high season), this time of year is marked with nearly perfect weather and is primetime for targeting Pacific sailfish on fly or light spin amongst other species including giant roosters and cubera snapper, and other heavyweights.


For a traveling fly fisherman seeking diverse new species or angling situations nothing is more exciting then floating down a new piece of water surrounded in unfamiliar vegetation and scenery, serenaded by eerie sounds drifting out of the forest, and casting unusual flies to exotic fish one has never seen before. For those seeking true adventure Northern Costa Rica is a land of lost waters and unique fly angling opportunities.


Caño Negro is a national wildlife refuge it is brimming in wading birds, spectacled caiman, and other interesting rainforest creatures.


At this location, fishing is generally good year-round, but the best times take place when waters flood the inland lagoons of Caño Negro from August until December. This period coincides with Costa Rica´s rainy season, so anglers can expect some precipitation. This is nature at its best!
