Marathon Florida Private Reef Charters

Targeting Snapper, Grouper, Mackerel, and More!

Reef fishing is the bread and butter of the Florida Keys, and for good reason — the reefs off Marathon are loaded with fish year-round, they’re a short run from the dock, and you don’t need any experience to have an incredible day on the water. I’m Captain Kevin Johnsen with Florida Keys Reel Adventures, and reef trips are where most of my anglers get their first taste of Keys fishing.

The short boat ride means more time with lines in the water and less time staring at the horizon. That makes reef fishing a great fit for families with kids, first-timers, and anyone who wants to get straight to the action. But don’t let the “beginner-friendly” label fool you — the reefs off Marathon produce serious fish. Even my experienced anglers love starting on the reef to load up the cooler with fresh fillets before we push out to the wrecks or offshore.

What You’ll Catch Reef Fishing in Marathon

The Marathon reef system is one of the most productive stretches in the Florida Keys, and there’s always something worth targeting no matter when you visit.

Yellowtail snapper are the year-round headliner — they’re aggressive, they bite consistently, and they’re some of the best eating fish in the ocean. You’ll catch them on nearly every trip, and they’re a blast for anglers of all ages.

Beyond the yellowtail, the reef and surrounding structure hold black grouper, red grouper, hard-charging yellowjacks, and lightning fast barracuda. There’s real variety down there, and part of the fun is never knowing exactly what’s going to grab your bait next.

Seasonal Fishing on the Marathon Reefs

The reef is always productive, but the seasons bring a rotating lineup that keeps things interesting trip after trip.

Winter is peak yellowtail season, and the action gets even better with cero mackerel, Spanish mackerel, and king mackerel moving through. Every now and then, a sailfish will show up right on the reef edge — and when that happens, it’s a day you won’t forget.

Late spring and summer bring some of the most exciting fishing of the year. The mutton snapper run peaks in May and June, putting big, hard-fighting fish on the reef. As soon as that winds down, the mangrove snapper spawn kicks off in June and July, and the bite can be absolutely lights-out.

I’m on these reefs constantly, so I know exactly what’s running and where to find them. Whatever the season, I’ll put you on the best bite available.

How the Trip Works

Reef trips are designed to be easygoing and action-packed from the start. We’ll head out to the reef, I’ll get you set up with the right tackle, and I’ll walk you through everything — how to bait your hook, how to feel the bite, how to set it and reel it in. Most people are catching fish within the first few minutes.

The goal is simple: have a great time on the water and go home with a cooler full of fresh fish. Whether that means helping your kid land their first yellowtail or putting you on a grouper that makes your whole trip.

Seasonal Special: Night Snapper Fishing (July & August)

If you want to experience something completely different, join me for a night snapper trip during the summer mangrove snapper spawn. This is a seasonal trip I run in July and August, and when the spawn is firing, the fishing is unreal.

As the sun goes down, the reef comes alive. Mangrove snapper, yellowtail, and mutton snapper feed aggressively after dark, and the bite under the moonlight can be nonstop. There’s something about fishing at night in the Keys — the quiet water, the stars, the sound of drag peeling in the dark — that turns a fishing trip into an experience you’ll talk about for years.

I mark this trip as intermediate because fishing in low light adds some extra challenge. If you’re newer to fishing, I’d recommend getting a daytime reef trip or two under your belt first so you’re comfortable with the basics before tackling the night bite. But if you’ve got some experience and want to try something most anglers never get to do, this is it.
