Freshwater fishing in Caño Negro offers a unique adventure in one of Costa Rica’s most remote and wildlife-rich wetlands. Located near the Nicaraguan border, the Caño Negro Wildlife Refuge features an intricate network of rivers, lagoons, and marshes surrounded by untouched tropical forest. Anglers are drawn by the diversity of freshwater game fish, including massive tarpon, some reaching up to 350 pounds, as well as snook, rainbow bass (guapote), machaca, mojarra, alligator gar, and drum fish. Beyond fishing, the area provides excellent wildlife viewing opportunities, with chances to see monkeys, turtles, caimans, and even elusive big cats such as jaguars and ocelots.
The wetlands’ calm, winding waterways create a setting reminiscent of the Amazon, with dense jungle and abundant wildlife surrounding each cast. Whether fly fishing or using light tackle, anglers can target a wide range of species, from aggressive rainbow bass to the challenging silver king tarpon. Local guides offer expert support, sharing tips, handling logistics, and helping ensure a safe and successful experience on the water.
