Costa Rica’s fisheries are defined by its two coastlines and rich inland waterways. The Pacific side is world-famous, particularly the central and northern coasts, where marlin, sailfish, tuna, and dorado migrate along deep offshore currents. The southern Pacific, around the Osa Peninsula and Golfo Dulce, offers year-round pelagic action plus inshore giants like roosterfish and cubera snapper. The Caribbean side, less traveled but equally rewarding, produces tarpon, snook, and other flats species around Tortuguero and Barra del Colorado. Freshwater systems like Lake Arenal and jungle rivers hold rainbow bass (guapote), machaca, and tilapia.
Seasonal bite patterns are distinct. On the Pacific, peak billfish season runs from December through April, especially for sailfish. Marlin are more common from May through September, alongside yellowfin tuna and dorado. Inshore fishing is reliable year-round, with roosterfish and snapper feeding along rocky points and reefs. The Caribbean sees tarpon runs strongest in spring and fall, with snook active in river mouths. Freshwater fishing is steady, with guapote and machaca feeding aggressively in warmer months.
Charter fishing is highly developed on the Pacific coast, particularly out of Los Sueños, Quepos, and Tamarindo. Offshore charters run from half-day trips for dorado and tuna to full-day runs for marlin and sailfish, with some multi-day liveaboards heading to offshore seamounts like FADs (fish aggregating devices). Inshore trips target roosterfish, snapper, and jacks with smaller boats. The Caribbean has fewer charter fleets but is known for guided tarpon lodges. Inland, fishing lodges and guides take anglers into jungle rivers and lakes.
Techniques vary widely. Offshore boats troll teasers, rigged ballyhoo, and artificial lures for billfish and tuna. Popping and live baiting are effective for roosterfish and snapper inshore. On the Caribbean side, tarpon are targeted with live bait, plugs, and flies. Freshwater anglers use spinning tackle, crankbaits, and fly gear for guapote and machaca. Costa Rica’s fisheries demand adaptability, with opportunities ranging from heavy offshore trolling to finesse fly fishing in rainforest rivers.
March through May is prime for sailfish offshore on the Pacific, with dorado and tuna also strong. Marlin activity picks up toward late spring. Inshore, roosterfish and snapper remain reliable. The Caribbean sees good tarpon runs in April and May. Freshwater rivers fish well, with guapote feeding aggressively in warming waters.
June through August brings strong marlin action on the Pacific, particularly blue and black marlin, plus steady yellowfin tuna. Dorado are consistent offshore, while roosterfish peak inshore. The Caribbean is wet but produces tarpon and snook during calmer weather windows. Freshwater fishing remains steady. Offshore trolling and popping dominate this season.
September through November is transitional on the Pacific, with dorado at their peak and tuna still biting. Sailfish activity slows, though marlin are caught. Inshore, roosterfish and snapper remain strong. The Caribbean enters one of its best tarpon seasons, with river mouths and lagoons full of fish. Inland rivers also fish well, especially for machaca.
December through February is peak sailfish season offshore, drawing anglers from around the world. Dorado are also abundant, with tuna and marlin mixed in. Inshore, roosterfish and snapper fishing continues year-round. The Caribbean sees some tarpon, though action is less consistent than in fall. Freshwater fishing is reliable during the dry season, with stable water levels.
Home to the largest sportfishing fleet in the country, Los Sueños is the epicenter of sailfish season. Offshore charters target sailfish, marlin, dorado, and tuna. Inshore trips produce roosterfish and snapper. Peak action runs December through April.
Another major Pacific hub, Quepos offers both offshore and inshore action. Sailfish and marlin dominate offshore trips, while roosterfish and cubera snapper thrive along the rocky coast. The annual Offshore World Championship is hosted here, drawing top anglers.
Located in Guanacaste, Tamarindo provides access to offshore marlin, sailfish, dorado, and tuna, plus excellent inshore fishing for roosterfish and snapper. The dry climate provides reliable fishing conditions nearly year-round.
The southern Pacific is one of Costa Rica’s richest ecosystems, with year-round fishing for marlin, sailfish, tuna, dorado, and roosterfish. Remote lodges and liveaboards provide access to offshore seamounts, plus incredible inshore fishing for cubera snapper.
This remote region is famous for tarpon and snook. The peak seasons in spring and fall produce world-class tarpon action in lagoons and river mouths. Fishing is typically lodge-based, with guided boats working rivers and coastal waters.
Costa Rica’s most famous freshwater fishery, Lake Arenal holds rainbow bass (guapote), machaca, and tilapia. Fishing is productive year-round, with best action in spring and summer. The lake’s jungle setting makes it a unique freshwater experience.
Yes, a recreational fishing license is required, available online or through local operators. Charters usually assist with obtaining it.
December through April is peak sailfish season, while May through September is best for marlin and tuna. Tarpon are strongest in spring and fall on the Caribbean side.
Los Sueños, Quepos, Tamarindo, Osa Peninsula, and Tortuguero are the top fishing hubs, each offering unique fisheries.
Half-day trips target inshore species like roosterfish and snapper. Full-day trips chase sailfish, marlin, and tuna offshore. Multi-day liveaboards access remote seamounts.
Most charters supply tackle, but bringing personal lures, flies, or popping gear is common. Offshore requires heavy trolling tackle, while inshore benefits from spinning or fly gear.
Yes, billfish are strictly catch-and-release. Other species like tuna, dorado, and snapper may be kept within limits.
Yes, inshore trips for roosterfish and snapper are great for families, while offshore marlin trips are more demanding.
Yes, particularly for roosterfish, snook, and snapper along beaches and river mouths. Access varies depending on location.
Half-day inshore trips start around $400–$600, while full-day offshore charters run $800–$1,500. Multi-day seamount trips cost significantly more.
