Looking for some serious bottom fishing action in the heart of the Florida Keys? Our half-day charters out of Marathon put you right on top of some of the most productive reefs in South Florida. We're talking about those spots where the snappers stack up thick and the grouper hang out in the structure, just waiting for the right presentation. With depths ranging from shallow 15-foot patches to deeper 100-foot ledges, we've got options for every angler and every tide. Whether you're after that cooler full of fillets or just want to bend some rods with your crew, this is your ticket to some world-class bottom fishing.
This isn't your typical tourist fishing trip – we're heading to the real deal spots where the locals go. Our captains know every ledge, every patch reef, and every piece of structure from the Bridge all the way out to the Atlantic side. Depending on conditions, tides, and what's biting, we might hit the protected bay waters for some mangrove action, run out to the Gulf side reefs for muttons, or punch it to the Atlantic drops where the big grouper live. The boat's rigged with everything you need – quality tackle, fresh bait, and all the terminal gear to get your offerings down to the fish. We keep it simple but effective, because when the fish are biting, you want to be ready to capitalize. Your fishing license is covered for up to six anglers, and we've got plenty of bottled water to keep everyone hydrated under that Florida sun.
We're primarily targeting structure-oriented species, so most of our fishing involves working baits near the bottom around reefs, ledges, and hard patches. We'll be using circle hooks with live and cut bait – think pilchards, ballyhoo, and squid strips that these snappers and grouper can't resist. The key is getting your bait down fast and keeping it in the strike zone without hanging up on the reef. We'll show you how to work the current, when to let your bait drift, and when to hold it tight to the structure. If the kings are around, we might throw out some live baits on the drift or even do some light trolling between spots. The tackle we provide is matched to the target species – heavy enough to turn a big grouper away from the rocks, but sensitive enough to feel those light snapper bites. Our mates will get you rigged up and keep you in fish all trip long.
The mutton snapper fishing has been absolutely on fire, especially around the deeper reefs in 40 to 80 feet of water. These fish are real fighters and excellent table fare – they'll test your drag and make some serious runs when hooked. Muttons are most active during moving water, and they can be picky about bait presentation, but when you dial them in, it's game on. Black grouper have been showing up consistently on the Atlantic side drops, particularly in the 60 to 100-foot range where they hole up in the ledges and caves. These bruisers will try to cut you off in the rocks, so it's all about applying pressure and getting them up and away from structure quickly. Grey snapper, including those tasty mangrove snappers, have been thick around the bridge pilings and nearshore patches, making for fast action when the bite is on. Red grouper are scattered throughout the area but seem most consistent on the Gulf side reefs in 30 to 60 feet. King mackerel have been making appearances during the cooler months, especially when we're fishing the edges and drop-offs, adding some variety to the fish box with their blazing runs.
Mutton Snapper are the crown jewel of Keys bottom fishing, and for good reason. These beautiful fish with their distinctive red coloration and forked tails typically run 2 to 8 pounds, though we see some real slabs pushing 10-plus pounds during peak season. They're most active from late fall through early spring when the water cools down, and they feed heavily on shrimp, crabs, and small fish around the reefs. What makes muttons special is their combination of fight and flavor – they'll make multiple runs and really test your skills, plus they're absolutely delicious on the dinner table.
Black Grouper are the heavyweights of the reef, with most fish ranging from 5 to 20 pounds, though monsters over 30 pounds show up regularly. These ambush predators sit tight to structure and will absolutely smoke whatever bait you put in front of them. The fight is all about the first few seconds – if you can turn them away from the rocks, you've got a great chance. Black grouper are year-round residents but seem most aggressive during the warmer months when they're more active. They're prized for their firm, white meat that's perfect for grilling or frying.
Grey Snapper, including those smaller mangrove snappers, provide consistent action and are perfect for anglers of all skill levels. These fish are curious and aggressive, often schooling up in large numbers around structure. Mangrove snappers typically run 1 to 3 pounds and are found in shallower water, while the larger grey snappers can push 5 pounds or more and prefer deeper reefs. They bite year-round but are most active during the warmer months. Their mild flavor makes them a customer favorite, especially for families with kids.
Red Grouper are another reliable target that provides excellent action. These fish typically range from 3 to 12 pounds and are found on sandy bottom areas adjacent to reefs. They're less aggressive than black grouper but more predictable, making them great targets when conditions are tough. Red grouper have a sweet, mild flavor and are incredibly versatile in the kitchen. They're most active during the day and will readily take cut bait presented near the bottom.

Mycteroperca BonaciBlack groupers are the heavyweights of our reef fishing trips. Most we catch run 10-30 pounds, but these brutes can hit 50+ pounds if you're lucky. They're ambush predators that hang tight to wrecks, ledges, and coral heads in 60-200 feet. Best action comes during cooler months when they move shallower, especially around the reef edges. What guests love about blacks is the pure power - once hooked, you're in for a serious tug-of-war. They'll use every ounce of strength to get back to their structure. The meat is outstanding too - mild, flaky, and perfect for any recipe. Here's the key: when you feel that bite, don't hesitate. Crank hard immediately and keep constant pressure. Let them get their head down and swim back to the rocks, and you'll likely lose both fish and tackle.
Lutjanus GriseusGrey snapper, also called mangrove snapper, are one of the smartest fish we target. Most range 1-3 pounds inshore, though offshore specimens can hit 5-8 pounds. These copper-red beauties are opportunistic feeders that love structure - docks, bridges, mangroves, and reef edges from shallow water to 100 feet. They bite year-round but are most active during warmer months and around full moons. What makes them popular is their excellent fight for their size and top-notch table fare. The white, flaky meat is some of the best eating you'll find. They're nocturnal by nature and can be finicky. My best tip: use live shrimp hooked through the tail, let it sink naturally, and be patient. Don't jig or move it too much - these fish like to study their prey before committing.
Scomberomorus CavallaKing mackerel are the speed demons of our offshore trips. These silver bullets average 15-40 pounds and are built for pure speed and power. They cruise the blue water from 40-150 feet, following baitfish and temperature breaks. Best fishing happens spring through fall when water temps hit 70-80 degrees. What makes kings special is their blistering runs and acrobatic fights - they'll peel line like nothing else out here. The meat's great too, with a rich flavor perfect for smoking or grilling. They're migratory, so timing matters. We typically troll live bait or spoons along the reef edges and drop-offs. Pro tip: always use a wire leader and rig with two hooks - one in the nose, one trailing behind. Kings love to bite the tail section of live bait, and that stinger hook will save you fish.
Lutjanus AnalisMutton snappers are one of our most prized catches here in Marathon. These beautiful fish typically run 2-4 pounds inshore, but can push 15+ pounds around deeper reefs. You'll spot them by their olive-pink color and distinctive blue streaks around the face. They love hanging around rocky bottom and coral heads in 30-100 feet of water. Best fishing happens during warmer months when they move into shallower areas to feed. What makes them special is their solid fight and excellent table fare - firm, white meat that's perfect for grilling. They're smart fish though, so presentation matters. My go-to trick is using the freshest bait possible on a light knocker rig and letting it drift naturally in the current. Once hooked, they'll try to run straight back to the rocks, so keep steady pressure and get them up quick.
Epinephelus MorioRed groupers are the bread and butter of our bottom fishing. These rusty-red beauties average 5-15 pounds and are known for their incredible fight and outstanding table fare. They prefer rocky and muddy bottoms in 30-200 feet, often around ledges, wrecks, and hard structure. Spring through fall offers the best action when they're most active. What guests love is the reliable bite and fantastic eating - firm, moist meat with a slightly sweet flavor that's perfect for any preparation. They're aggressive feeders that'll hit live or dead bait, especially shrimp and crabs. The trick with reds is being ready for a long battle. They're incredibly strong for their size and will use every bit of cover available. Use heavy tackle and don't give them an inch once hooked, or they'll wrap you up in the structure.
