Flamingo Marina is the hub of one of Costa Rica's most active sportfishing operations. The marina sits between Flamingo and Playa Potrero and operates full-service facilities for private boats and charter vessels. Offshore fishing targets sailfish and marlin — the season peaks from November to April for sailfish, though the fishing is productive year-round — and dorado (mahi-mahi) and yellowfin tuna are common offshore catches as well. Inshore charters go after roosterfish, snapper, and jack crevalle in the shallower water closer to the coast.
Full-day and half-day charters are available through the marina and several operators in town. Most include tackle and bait; some are catch-and-release only, a practice increasingly common on the Guanacaste coast. Prices are higher than at smaller fishing villages but the boats and equipment are generally well-maintained.
