This guide is for anglers planning fishing in Costa Rica, from first-timers booking a half-day charter to repeat visitors chasing a marlin on fly. The short answer: the Pacific is the main event, with sailfish, marlin, dorado, tuna and roosterfish, and the best months depend on which part of the coast you fish. The Caribbean side is smaller and wilder, built around tarpon and snook. Below you’ll find the best months by region, where to base yourself, what charters cost and the license and release rules you need to know before you go.
Fishing in Costa Rica at a Glance
- Best overall window: December through April, the dry season, especially for central and southern Pacific sailfish.

- Top species: sailfish, blue, black and striped marlin, dorado (mahi-mahi), yellowfin tuna, roosterfish, cubera snapper, tarpon and snook.
- License: everyone fishing from a boat needs an INCOPESCA permit: about $15 for 8 days, $25 for 30 days or $50 for a year.
- Release rules: sailfish, marlin, roosterfish and tarpon must be released alive.
- Charter costs: roughly $550 to $950 for a half day offshore and $1,100 to $1,500 for a full day, per boat.
Best Time to Fish in Costa Rica
Costa Rica fishes year-round, but each coast has its own rhythm. Use this table as a starting point, then ask your captain how the current season is running.
| Region | Best months | Main targets | Bases |
|---|---|---|---|
| North Pacific (Guanacaste) | May–August; windier December–April | Marlin, sailfish, tuna, roosterfish | Flamingo, Tamarindo, Playas del Coco |
| Central Pacific | December–April, peaking around February | Sailfish, marlin, dorado, roosterfish | Quepos, Los Sueños (Herradura), Jacó |
| South Pacific | December–April | Marlin, sailfish, tuna, wahoo, roosterfish | Golfito, Puerto Jiménez, Drake Bay |
| Caribbean | January–May and September–October | Tarpon, snook | Barra del Colorado, Tortuguero |
| Lake Arenal (freshwater) | December–April | Rainbow bass (guapote), machaca | La Fortuna, Nuevo Arenal |
Dorado and tuna tend to be strongest in the rainy months, roughly May through September, which makes the green season a good bet if you care more about fish for the cooler than a billfish photo.
Where to Fish in Costa Rica
Central Pacific: Quepos and Los Sueños
This is Costa Rica’s sportfishing capital and the easiest place to book on short notice. The marina at Quepos (Pez Vela) and Los Sueños at Playa Herradura both run large charter fleets, and both are an easy drive from San José. In season, offshore boats target sailfish and marlin, while inshore trips go after roosterfish and snapper along the rocky coast. Quepos pairs well with Manuel Antonio National Park, and our list of hotels in Quepos and Manuel Antonio covers where to stay.
North Pacific: Guanacaste
Flamingo, Tamarindo and Playas del Coco are the main bases. Offshore, the Catalina Islands and the area around the Bat Islands are known for big pelagics, and the inshore rocks and reefs hold roosterfish and snapper. The catch is the wind: from roughly December through April, Papagayo winds can blow hard enough to cancel or shorten trips. If you’re flexible on dates, the calmer months from May through August are when this coast shines.
South Pacific: Golfito and the Osa Peninsula
The south is less crowded and more remote. Golfito and Puerto Jiménez sit on the Golfo Dulce, with lodges that combine offshore runs for marlin, sailfish, tuna and wahoo with inshore fishing for roosterfish and cubera snapper. Drake Bay works for anglers who also want time in Corcovado National Park. Many visitors fly in on a domestic flight to skip the long drive.
Caribbean Coast: Tarpon and Snook
The Caribbean is a specialist’s fishery. Barra del Colorado, near the Nicaraguan border, is the traditional base for tarpon, with snook in the river mouths and lagoons. Infrastructure is thin, so most anglers book a lodge package that includes boats and guides. Getting there usually means a boat or small plane, much like getting to Tortuguero. Read more in our guides to tarpon fishing and snook fishing in Costa Rica.
Freshwater: Lake Arenal
Lake Arenal, the country’s largest lake, is the go-to freshwater option. The main target is the rainbow bass, called guapote locally, along with machaca. Guided trips leave from the lake shore near La Fortuna and Nuevo Arenal, which makes this an easy add-on to an Arenal itinerary.
Inshore vs. Offshore Fishing in Costa Rica
Offshore trips run well out to sea, often 20 to 40 miles depending on conditions, in search of sailfish, marlin, dorado and tuna. They take longer, cost more and are best done as a full day if billfish are the goal.
Inshore fishing stays along the coast, around rocks, reefs and river mouths. Roosterfish are the headline species, along with cubera snapper, jacks and snook. Inshore trips are shorter, cheaper and a smart choice for families, first-timers or anyone prone to seasickness. See our roosterfish guide for spots and tactics.
Costa Rica Fishing Charter Costs
Prices vary with boat size, port and season, and they’re usually quoted per boat, not per person. As a rough guide for offshore sportfishing boats:
- Half day: about $550 to $950
- Three-quarter day: about $775 to $950
- Full day: about $1,100 to $1,500
Inshore trips on smaller boats usually cost less. Before you book, confirm what’s included: fuel, tackle, bait, licenses, drinks and lunch, and if the price includes tax. A tip for the crew is customary; see our guide to tipping in Costa Rica.
Fishing License and Rules
Costa Rica’s fisheries institute, INCOPESCA, issues the permits and sets the rules. The key points:
- Everyone on board needs a license. Each person fishing from a boat must carry an INCOPESCA permit. You can buy it online through INCOPESCA or at its regional offices, and many charters handle it for you.
- Permit options: about $15 for 8 days, $25 for 30 days and $50 for a year. Longer permits require a photo and a copy of your ID.
- Billfish are catch and release. Sailfish and marlin must be released alive. Captains keep the fish in the water for photos and cut the line close to the hook.
- Roosterfish and tarpon are also release-only.
- No selling your catch. Sport-caught fish can’t be sold, and a trip may land a limited number of fish, generally up to five, for eating or taxidermy.
- No fishing in national parks. Sport and commercial fishing are banned in national parks, biological reserves and natural monuments, including Manuel Antonio, Corcovado, Marino Ballena and Cocos Island.
What to Bring
- Polarized sunglasses, a hat with a neck flap and reef-safe sunscreen
- Lightweight long sleeves and quick-dry pants
- Seasickness medication, taken before you leave the dock
- Cash for the crew tip and any extras
- Your own fly or light-tackle gear if you have a preference; most charters supply conventional tackle
Common Mistakes to Avoid
- Booking Guanacaste offshore trips in peak wind season without a backup day.
- Choosing a half day for billfish. The run offshore eats into short trips.
- Assuming the price is per person. Most quotes cover the whole boat.
- Planning to keep a sailfish or marlin. They must go back alive.
- Forgetting the license. Ask if your charter includes it; if not, buy it before the trip.
