For anglers who crave the ultimate challenge, big tuna adventures in Costa Rica deliver everything you could dream of: power, endurance, and the kind of offshore excitement you never forget. Out past the continental shelf, Costa Rica’s deep blue Pacific waters are home to massive yellowfin tuna that can exceed 200 pounds. These trips combine adventure, comfort, and nonstop action in one unforgettable experience.

Whether you’re fishing overnight seamounts, offshore FAD zones, or deep ocean ridges near the Osa Peninsula, here’s what you can expect from a multi-day tuna expedition with Fish Costa Rica.

Why Go Offshore for Tuna?

Yellowfin tuna travel in vast schools that often move far offshore following currents and bait concentrations. While smaller fish (40–100 lb) are common closer to land, the true giants, 150 to 250 pounds and more, usually patrol the deep blue beyond 60 miles. To reach them, captains head out on overnight or multi-day trips that allow more time in these productive waters.

These long-range adventures combine big-game sportfishing with comfortable at-sea living. Modern offshore boats feature air-conditioned cabins, bunks, full galleys, and all the gear needed for an extended time offshore. You’ll fall asleep under the stars and wake up surrounded by dolphins, birds, and boiling tuna.

Fishing FAD Zones for Big Tuna

Costa Rica’s Fish Aggregating Devices (FADs) are legendary among serious anglers. These floating structures attract baitfish, which in turn draw predators like marlin, sailfish, dorado, and of course, giant yellowfin tuna. Most FADs lie between 60 and 120 miles offshore, making them ideal for overnight charters or two-day expeditions.

The FADs are especially productive from May through October, when warm, nutrient-rich waters bring in massive schools of tuna. While marlin are the headline species for FAD trips, the tuna fishing can be just as explosive, often producing fish over 150 pounds on live bait or poppers.

Typical FAD Tuna Setup

  • Reels: 50–80 lb class conventional setups (Shimano Tiagra or Penn International)
  • Lines: 80–100 lb test with 100–130 lb fluorocarbon leader
  • Bait: Live bonito, skipjack, or mackerel
  • Lures: Large jet heads, deep-diving plugs, or heavy poppers

Captains usually arrive at the FADs before sunrise and fish throughout the day, switching between trolling and live baiting depending on the bite. It’s common to see tuna crashing bait on the surface all around the boat.

Overnight Tuna Charters Explained

Overnight tuna charters typically leave the dock in the afternoon, cruise overnight to offshore grounds, and begin fishing at first light. After a full day of action, anglers rest onboard while the crew continues scouting for the next day’s location.

Sample Overnight Itinerary

  • 3:00 p.m. – Departure: Leave from Los Sueños, Quepos, or Golfito.
  • Sunset: Enjoy dinner onboard while heading to offshore grounds.
  • 5:30 a.m. – Fishing begins: Crews locate tuna schools with sonar, birds, and dolphins.
  • Midday: Fight and land big yellowfin, sometimes alongside marlin and wahoo.
  • Evening: Relax, eat, and prepare for the next day’s action before returning to port.

Boats used for these trips range from 36 to 60 feet and are equipped with everything from satellite communication to full sleeping quarters and private heads. Comfort and safety are top priorities; you’ll be well-fed and well-rested even while far offshore.

Best Regions for Big Tuna Trips

Los Sueños & Herradura

Los Sueños Marina is the top launching point for overnight tuna trips on the Central Pacific coast. Boats here can access multiple FADs within 100 miles, offering chances at both giant tuna and marlin. Calm seas and professional crews make Los Sueños a perfect choice for serious anglers or small groups.

Quepos & Marina Pez Vela

Departing from Quepos, anglers reach some of the most productive offshore ridges and seamounts in the country. Multi-day trips here often combine marlin and tuna fishing, giving you a shot at multiple trophy species in one journey.

Golfito & The Southern Zone

In the far south, Golfito serves as the gateway to Costa Rica’s most remote bluewater. The tuna here are massive, often 150 pounds and up, and the scenery is unforgettable. Many anglers choose Golfito for extended 2–3 day charters due to its proximity to untouched offshore grounds.

Targeting Giant Tuna Offshore

Fighting a big yellowfin is unlike any other fishing experience. These fish can strip 300 yards of line in seconds, then dive straight down. Fights can last over an hour, requiring teamwork, technique, and patience. Captains use fighting harnesses and stand-up gear to help anglers maintain control without exhaustion.

Common methods include trolling large live baits, dropping metal jigs, or casting heavy poppers into breaking schools. Every strike is explosive, and when the rod doubles over, the adrenaline rush is immediate.

Species You’ll Encounter

While tuna are the main attraction, overnight offshore trips often produce an incredible mix of species:

  • Blue Marlin – Frequently hooked around FADs.
  • Sailfish – Common alongside tuna schools.
  • Dorado (Mahi-Mahi) – Often near floating debris.
  • Wahoo – Known for blistering strikes at sunrise.

It’s this variety that makes overnight tuna trips one of the most rewarding experiences in Costa Rica sportfishing.

Comfort and Amenities Onboard

Modern overnight boats are built for both performance and comfort. Amenities include:

  • Air-conditioned cabins and bunks
  • Private bathrooms with hot showers
  • Full kitchen and dining area
  • Satellite phone and safety equipment
  • Cold drinks, meals, and snacks included

It’s a far cry from roughing it; you’ll enjoy world-class fishing with the comforts of a floating hotel.

Responsible Fishing and Conservation

Costa Rica enforces responsible fishing practices through INCOPESCA regulations. Crews use circle hooks and proper bleeding techniques to ensure sustainable harvests. Guests are encouraged to keep only what they plan to eat and release excess fish. Conservation is at the heart of every offshore expedition we organize.

Who Should Try a Big Tuna Adventure?

Overnight and multi-day tuna trips are ideal for:

  • Experienced anglers seeking large tuna or marlin
  • Groups of friends or families wanting a unique offshore adventure
  • Photographers and ocean enthusiasts looking for wildlife encounters
  • Anyone ready to experience Costa Rica’s wild bluewater at its best

Whether it’s your first offshore trip or your tenth, nothing compares to watching a sunrise 100 miles from shore, surrounded by birds, dolphins, and boiling tuna.
