Year-round, with peak season for migratory adults from March through June.
Known as the 'Silver King,' tarpon are one of the most sought-after game fish in the world, offering an incredible fight and aerial acrobatics.
Tarpon fishing in Marathon is a year-round pursuit, with the peak season for large migratory fish typically running from March through June. Anglers often target these powerful fish with heavy-duty spinning or conventional tackle, using live bait or artificial lures. For fly anglers, an 11-weight rod is standard for the big migratory tarpon, while a 9-weight can handle the smaller, resident juveniles found in the backcountry.
Tarpon are iconic predators of our coastal waters, recognized for their immense strength and spectacular leaps when hooked. These fish can grow to impressive sizes, making them a true test of skill and endurance for any angler. They inhabit a variety of environments, from shallow flats and mangrove-lined backcountry channels to nearshore reefs and passes. Catching tarpon involves a combination of patience and precise technique. Whether you're drifting live mullet or pinfish, casting large flies, or working topwater plugs, the strike is often explosive. Once hooked, tarpon are known for their incredible runs and powerful head shakes, often launching themselves clear out of the water in an attempt to throw the hook. It's crucial to have stout tackle and a good understanding of how to manage the fight to bring one of these magnificent fish to the boat. While tarpon are present throughout the year in South Florida, the arrival of large migratory schools during the spring and early summer months is what draws anglers from around the globe. These fish are on a mission, and targeting them in the channels and nearshore waters around Marathon can provide some of the most exciting fishing experiences imaginable. We also have resident tarpon that can be found in our back bays and mangrove estuaries, offering excellent opportunities for anglers looking for a different kind of challenge.
