Deep Sea Fishing Quepos
Go deep on the Pacific: blue marlin, black marlin, giant yellowfin tuna, and world-record sailfish in the offshore waters of Quepos.
The Ultimate Deep Sea Fishing Experience off Quepos
For anglers who dream of fighting Pacific blue marlin, black marlin, and giant yellowfin tuna in the deep blue, the waters off Quepos are one of the best options on the Pacific coast. The eastern Pacific off Costa Rica's central coast sits at the intersection of major ocean currents that create high deep-water productivity, drawing in marlin, giant tuna, and other large pelagics to waters accessible from the Quepos Marina.
Our deep sea fishing charters run premium vessels 40–80 miles offshore to reach the grounds where the deep blue water holds the largest fish. These are not the waters visible from shore. They're the true ocean, where the depth drops to thousands of meters and the biggest predators in the Pacific come to hunt.
Pacific blue marlin are the biggest challenge in big game fishing. They can reach 1,000+ pounds, fight for hours, strip line at speeds over 50 mph, and jump well above the water's surface. Hooking a 500-pound blue on heavy tackle is one of the most demanding experiences in sport fishing.
The yellowfin tuna schools in the deep water off Quepos produce some of the largest specimens anywhere. Fish regularly reach 100–150 pounds and school in the current breaks, targetable with both trolling and live bait techniques. Fighting a giant yellowfin to the boat is an exercise in pure physical endurance that tests even experienced anglers.
Our deep sea captains are specialists with decades of experience reading the offshore environment, understanding current patterns, and locating the specific conditions that concentrate the biggest fish. Their knowledge is what puts clients on fish consistently.

Deep sea fishing targets species that live in water 200+ feet deep, typically 40–80+ miles offshore. The primary targets are blue and black marlin, giant yellowfin tuna, and bigeye tuna. This requires larger, faster boats, heavier tackle, longer fishing days, and captains who specialize in reading deep blue water conditions. The rewards are proportionally spectacular.

Pacific blue marlin caught off Quepos regularly exceed 400–500lbs, and fish over 1,000lbs are occasionally encountered. Black marlin reach similar sizes. These are among the largest, most powerful fish in the ocean. A marlin hookup on full heavy tackle is one of the most physically demanding and exhilarating experiences in sport fishing.
