FAD fishing in Costa Rica is the pinnacle of offshore big game angling. Far beyond the traditional day charter grounds lies a chain of deep water seamounts and Fish Aggregating Devices where blue marlin feed aggressively, often producing release numbers that anglers can only dream about. These multi-day expeditions, departing mainly from Los Sueños, Quepos, and the southern Pacific, offer some of the most consistent marlin action in the world for anglers seeking non-stop billfish encounters and the ultimate offshore adventure. FAD fishing in Costa Rica is unmatched.
These trips take you far offshore to remote seamounts that rise from thousands of feet of water. Ocean currents push bait into these zones, attracting predators such as blue marlin, black marlin, sailfish, big dorado, and massive yellowfin tuna. Because these seamounts sit in isolated offshore corridors, fishing pressure is low, and the action can be spectacular from morning through evening.
FAD trips combine adventure, skill, comfort, and endurance into a once-in-a-lifetime experience, making them perfect for experienced anglers, groups, and anyone who has dreamed of catching marlin after marlin in deep blue Pacific water.
What Is FAD Fishing
A FAD is a Fish Aggregating Device positioned offshore to attract baitfish, which in turn attract predators. Costa Rica’s Pacific coastline is uniquely positioned near natural underwater mountains where these devices hold massive amounts of life. The result is one of the most productive marlin fisheries on the planet.
FAD fishing is very different from day trips. Boats travel 80 to 150 miles offshore, spending multiple days at sea to maximize time on the seamounts. Most trips last 2 to 4 days, with overnight travel, comfortable cabins, and around-the-clock fishing opportunities.
Anglers often experience several dozen marlin encounters in a single trip, with seasons where triple-digit release numbers are possible. The combination of calm offshore conditions and heavy bait presence creates a perfect environment for nonstop action.
Blue Marlin Capital of the World
Costa Rica’s seamount region is widely recognized as one of the best places on earth for blue marlin. These fish feed aggressively and remain active throughout the day. Unlike traditional billfish trips where encounters may be spaced out, FAD fishing offers frequent shots at marlin and multiple hookups at once when the bite is strong.
On many trips, anglers experience:
Continuous blue marlin strikes
Sailfish mixed in throughout the day
The possibility of encountering black marlin
Large dorado around floating debris
Giant yellowfin tuna under birds and dolphins
Because these waters sit far from coastal pressure, marlin behave naturally and feed aggressively. Every trip is an opportunity to push personal records, build angling skills, and experience what many consider the best big game fishing on earth.
Multi-Day Charter Experience
A FAD trip is a complete offshore expedition. Boats depart in the afternoon or evening, traveling through the night to reach the seamounts at sunrise. Comfortable sleeping quarters, air-conditioned cabins, full kitchens, and experienced crews make the trip smooth and enjoyable.
Fishing begins at first light and continues throughout the day. Many boats fish late afternoon into sunset, then drift or slow troll at night, depending on the conditions and the captain’s plan. Crews prepare meals, monitor lines, assist anglers, and adjust tactics to follow bait and current lines.
The atmosphere on a multi-day trip is focused, exciting, and unforgettable. Every sound, every surface ripple, and every teaser splash could signal another marlin strike.
Techniques Used on FAD Trips
FAD fishing uses highly specialized offshore techniques, including:
Teaser and pitch bait fishing
Live bait slow trolling
Circle hook switch baiting
Dredge systems for raising marlin
Artificial lures and surface baits
Kite setups when tuna appear
Switch baiting is one of the most exciting aspects of these trips. Crews tease marlin up on large attractors, then anglers pitch rigged baits to the fish for a visual, adrenaline-filled hookup. The clarity of offshore water and the aggressive nature of blue marlin make for unforgettable encounters.
Species You Can Catch
While blue marlin are the main attraction, FAD trips produce a wide range of species.
Blue Marlin
The most common species encountered is with nonstop action in peak seasons.
Black Marlin
Found around certain seamounts and often larger than blue marlin.
Striped Marlin
Occasional but present depending on water temperature and currents.
Sailfish
Mixed throughout the season, providing additional surface action.
Yellowfin Tuna
Some of the largest tuna caught in Costa Rica come from seamount waters.
Dorado
Bright, acrobatic, and often plentiful around floating debris.
Wahoo
Occasional fast-moving strikes around the structure or current edges.
Best Time for FAD Fishing in Costa Rica
FAD fishing can be done year-round, but certain months stand out for peak action.
December to April
Calm seas, consistent marlin numbers, excellent overall conditions.
May to August
Considered by many captains to be one of the best periods for pure marlin quantity. Tuna numbers are substantial as well.
September to November
Weather can vary, but marlin action remains strong, and crowds are lower. Dorado and tuna fishing increase with seasonal currents.
Because the seamounts sit far offshore and outside standard weather patterns, conditions are often stable even during transitional seasons.
Who FAD Fishing Is For
FAD fishing is ideal for:
Serious anglers
Groups seeking a bucket list adventure
Experienced fishers wanting to improve marlin skills quickly
Anglers who wish to experience constant action
Those seeking a world-class multi-day offshore experience
It is not recommended for travelers who prefer short boat rides, calm inshore conditions, or first-time anglers who may find offshore expeditions overwhelming.
