Captain Kit Carson's Complete Guide
How to Plan a Fishing Trip in Islamorada
Picking the right charter, timing your trip, what to pack, what it costs, and what you'll catch. Written by a captain who's been running these waters for over a decade.
The Short Answer
To plan a fishing trip in Islamorada, Florida: choose your target species by season (sailfish Nov to Apr, mahi May to Oct), pick between a half-day (4hr), ¾-day (6hr), or full-day (8hr) charter, book a licensed captain online or by phone, and show up with sunscreen and an appetite for action. Islamorada is called the "Sport Fishing Capital of the World" for a reason. The Gulf Stream runs tight to the reef, bait is thick, and the pelagics follow. DirtyBoat Charters runs out of Robbie's Marina on the 42' Liberty Express. Trips start at $475/person for split charters, $1,200 for private half-days, $1,800 for ¾ day, and $2,200 for a full day, each plus a fuel surcharge ($50/seat on splits, $200/trip private, $500 swordfish). Repeat clients get 10% off.
1. Why Islamorada for Fishing?
Islamorada isn't called the "Sport Fishing Capital of the World" because someone made it up. The geography here is genuinely exceptional. The Gulf Stream runs closer to Islamorada than almost anywhere else in the Keys, sometimes within 4 to 7 miles of the reef line off Alligator Reef and Molasses Reef.
That matters because the Gulf Stream is the highway. It carries warm, clear blue water loaded with baitfish and the predators that follow them: sailfish, mahi-mahi, wahoo, blackfin tuna, kingfish. When the stream rides tight to the reef (which it does frequently off Islamorada), you don't have to run 40 miles offshore to find world-class fishing. You're on it in 20 minutes.
Add the extensive reef system (Molasses, Conch, Davis, Alligator, Crocker, and Tennessee reefs) and you've got nearshore fishing for snapper, grouper, and amberjack on top of the offshore bite. Islamorada fishes multiple directions, multiple depths, all year round.
We launch from Robbie's Marina in Islamorada, one of the most iconic fishing docks in the Keys. The fish literally swim by the dock.
2. Best Time of Year to Fish Islamorada
The honest answer: Islamorada fishes well year-round. But here's how the seasons break down by target species:
Winter / Spring (Nov to Apr)
- 🎣 Sailfish: peak season, kite fishing on the reef line
- 🎣 Kingfish: stacked on the reef
- 🎣 Wahoo: offshore current edges
- 🎣 Blackfin Tuna: humps and current edges
- 🎣 Cobia: following rays inshore
- 🎣 Mutton & Yellowtail Snapper: year-round on the reef
Summer / Fall (May to Oct)
- 🎣 Mahi-Mahi: peak season, weedlines offshore
- 🎣 Blackfin Tuna: year-round, peaks summer
- 🎣 Wahoo: offshore, fast trolling
- 🎣 Swordfish: deep drop 1,200 to 1,800ft, daytime
- 🎣 Tarpon: inshore April to June
- 🎣 Snapper & Grouper: reef fishing year-round
Captain's Take
"If I had to pick one month, I'd say March or April. The sailfish bite is firing, the weather is mild, the stream is close, and the crowds haven't hit yet. But I've had epic days in every single month of the year out here. The Keys don't really have an off-season, just different fish."

3. What Fish Can You Catch in Islamorada?
Here's what's realistically catchable. Not the optimistic brochure version, the actual honest breakdown:
Sailfish
The signature Islamorada catch. Kite fishing with live ballyhoo on the reef line Nov to Apr. Catch and release, these are pure sport fish. Multiple bills in a day is not uncommon when the bite is on.
Mahi-Mahi (Dolphin)
The fun fish. Schools up on weedlines and floating debris offshore May to Oct. Fast, acrobatic, and delicious. Great for groups and first-timers.
Wahoo
The speed demon. Fast trolling offshore current edges. Explosive strikes and scorching runs. Excellent table fare. Nov to Apr and year-round on the right conditions.
Blackfin Tuna
Year-round on the humps and current edges. 10 to 30 lbs typical. Sushi-grade fish. Often caught mixed in with sailfish.
Kingfish (King Mackerel)
Reef line Nov to Apr. Aggressive strikers on live bait and trolled lures. Great fight on light tackle.
Swordfish
Daytime deep-dropping 1,200 to 1,800 feet offshore. Specialized charter, heavy tackle, high skill ceiling. Trophy fish.
Mutton & Yellowtail Snapper
Year-round on the reef. Great for kids and beginners. Multiple fish days are common. Excellent eating.
Amberjack
Deep reef structure and wrecks. 40 to 80 lbs. Pure brute. If you want a workout, this is your fish.
4. Choosing the Right Charter
There are two main decisions: duration and private vs. split.
Duration
Half Day
4 Hours
Best for: Families, beginners, reef fishing
7 AM to 11 AM or 1 PM to 5 PM. Enough time to get offshore and catch fish. Best for kids.
¾ Day
6 Hours
Best for: Best value, most versatile
7 AM to 1 PM. Enough time to run offshore, find the fish, and work the bite properly. Our sweet spot.
Full Day
8 Hours
Best for: Serious anglers, swordfish, wahoo
7 AM to 3 PM. Max range, max effort, max results. Best for experienced groups chasing trophy fish.
Private vs. Split Charter
Private Charter
- ✅ Just your group, the captain, and the mate
- ✅ You set the agenda: species, style, pace
- ✅ Great for families, corporate groups, celebrations
- ✅ Captain focuses 100% on your group
- ⚡ Higher total cost, lower per-person if you have 4 to 6 people
Split Charter
- ✅ Share the boat with 1 to 3 other anglers
- ✅ Best per-person price, from $475/seat (+ $50/seat fuel)
- ✅ Great for solo travelers or couples
- ✅ Meet other anglers, social experience
- ⚡ Max 4 anglers total, trip happens with 4 booked
5. What to Expect on the Water
First time on a charter? Here's what your day actually looks like aboard the 42' Liberty Express:
Arrive at Robbie's Marina, Islamorada. Meet Captain Kit and the mate. Gear briefing, safety rundown.
Lines off. We run offshore, typically 15 to 25 minutes to the reef edge depending on where the action is.
Lines in. Kites up if we're sailfishing, rods out if we're trolling. Captain reads the water and adjusts.
Fish. Captain handles the tactics, you handle the rod. Mate rigs bait, handles gaffs, keeps you in the action.
Run back to dock. Mate cleans and bags your catch. Captain walks you through what you caught.
The boat is fully equipped: outriggers, fighting chairs, live bait wells, fish finder, radar, and an air-conditioned cabin when you need a break. Fishing licenses are included for everyone on the boat. You don't need to bring a single piece of fishing gear.
6. What to Bring

- ☀️ Reef-safe sunscreen (reapply every 2 hours)
- 🧢 Hat and polarized sunglasses
- 👟 Non-slip, closed-toe shoes (no flip flops offshore)
- 🧴 Seasickness medication if prone (take the night before), or a drug-free Reliefband wristband

8. Islamorada vs. Key West vs. Key Largo for Fishing
If you're choosing where to base your fishing trip in the Florida Keys, here's the honest comparison:
Islamorada, the sweet spot
The Gulf Stream is closer here than anywhere in the Keys. You spend less time running and more time fishing. The reef system is exceptional. The town is built around fishing culture, where every marina, every tackle shop, and every conversation is about fish. No sprawling tourist traps eating your time.
Key West, great but different
Bigger party scene, more charter boats, but the stream is further out. You're paying for more run time to get to the same fish. Better for wreck fishing and tarpon. More nightlife if that's your thing.
Key Largo, closer to Miami, more reef
Easiest drive from Miami. John Pennekamp Coral Reef State Park is incredible for diving and reef fishing. But the stream is a longer run than Islamorada and the offshore fishing isn't as concentrated.
Bottom line: if offshore sportfishing for sailfish, mahi, wahoo, and tuna is your goal, Islamorada is the answer.
9. Where to Stay in Islamorada
Most of our charter guests stay within 10 to 15 minutes of Robbie's Marina. Islamorada has everything from waterfront resorts to laid-back vacation rentals, and the whole island is only about 18 miles long, so nothing is far from the dock.
Oceanside resorts (MM 80 to 84)
Full-service resorts with pools, restaurants, and ocean access. Good for families and groups who want everything on-site. You're 5 to 10 minutes from the marina.
Vacation rentals and cottages
Private homes and cottages with docks, kayaks, and grills. Best value for groups of 4+. Most have boat-trailer parking if you're bringing your own skiff for the backcountry.
Bayside lodges (MM 75 to 80)
Quiet, sunset-facing spots on Florida Bay. Great for couples. Closest to Robbie's Marina at MM 77.5, and some are walking distance to the dock.
Captain's Tip
"Book your stay between Mile Marker 75 and 84. You'll be close to the marina, close to restaurants, and close to everything else Islamorada has to offer. Don't overthink it. Just get something on the water."
