Miami to Key West and Back: The 10-Day Keys Run

Ten days gives the full Florida Keys enough room to breathe. Leave Miami behind, work south through Key Largo, Islamorada, and Marathon, spend two nights in Key West — then turn north and experience the chain again without simply retracing the same vacation.

The advantage isn't just seeing more. It's having time: fish Islamorada in one direction and explore the backcountry in the other, snorkel a reef because conditions are perfect that morning rather than because a schedule says you have ninety minutes, and give Key West a full day instead of treating it like a finish line.

What this 10-day Keys itinerary covers

A ten-night round trip from Miami through Key Largo, Islamorada, and Marathon to Key West, then back north through the chain. The yacht covers the mileage in the mornings so the afternoons belong to reefs, fishing, sandbars, and time ashore — with marina berths throughout, which is exactly what you want on this coastline.

Best for groups who want the whole Keys without a one-way repositioning charge — and who would rather give the trip enough time than turn a private yacht vacation into a race down the coast. Motor yacht only: two of these legs stretch past five hours at sailing speed, and the ten-day pacing exists precisely so no day feels like a delivery.

Day 1 of 10 · Miami embark

Unpack Once

Anchorage: Miami (marina)

Board at the Government Cut or Miami Beach marinas — under an hour from either airport — with the crew dockside and ten days of provisioning already struck below. The shakedown afternoon runs the skyline and Biscayne Bay, and the chart briefing lays out the shape of the thing: south for five days, the turn at Key West, and a northbound return that keeps what the southbound teased.

Dinner aboard against the lit skyline. The chain starts at breakfast.

Day Highlights

  • One embarkation, ten days, zero repacking.
  • Biscayne Bay shakedown and the full-route briefing.
  • Miami's skyline as the send-off.

Day 2 of 10 · Southbound

First Reef

Anchorage: Key Largo (marina)
Key Largo's sanctuary reef — the chain's underwater welcome mat.
Key Largo's sanctuary reef — the chain's underwater welcome mat.

The longest leg of the entire ten days goes first and still finishes by lunch: forty-four miles down Hawk Channel with the reef line coloring the water to starboard and the first lines out as the depth breaks. Key Largo's marine-sanctuary reef sits minutes off the marina, and the afternoon belongs to it.

First slip of the chain, first conch fritters, first of many marina evenings where the fleet's day filters down the dock in fish stories.

Day Highlights

  • The ten days' longest leg — done by lunch.
  • Sanctuary snorkeling minutes off the slip.
  • Dockside fish-story hour, night one.

Day 3 of 10 · The capital

Islamorada, First Pass

Anchorage: Islamorada (marina)
Islamorada's bay side — the sandbar-and-flats register of the middle chain.
Islamorada's bay side — the sandbar-and-flats register of the middle chain.

An hour's hop opens a full day in the sport-fishing capital: flats skiffs into the backcountry, the offshore fleet to the hump, or the yacht's own cockpit settling the question directly. The marina scales adjudicate at five o'clock.

Non-anglers get the sandbars — miles of knee-deep bay-side warmth — and everyone gets the Islamorada dinner ritual: the day's catch handed across the dock to a kitchen that knows what to do with it.

Day Highlights

  • Flats, hump, or cockpit — pick a fight.
  • Bay-side sandbars for the swim contingent.
  • Catch-to-kitchen dinner, the local sacrament.

Day 4 of 10 · The middle chain

Under the Seven Mile Bridge

Anchorage: Marathon (marina)
The middle Keys at dusk — boatyards, fish houses, and the chain's biggest bridge.
The middle Keys at dusk — boatyards, fish houses, and the chain's biggest bridge.

Two hours south through the counting-down bridges to the chain's working middle. Marathon does boatyards and fish houses where Key West does costume, and its headline is best seen exactly the way you're seeing it: the Seven Mile Bridge from the water, from a flybridge, at whatever speed makes the photographer happy.

Sombrero Reef fills the snorkel slot, the Turtle Hospital covers the families, and the slip takes the boat for the night before the run to the turn.

Day Highlights

  • The Seven Mile Bridge, flybridge view.
  • Sombrero Reef snorkeling.
  • The chain's honest working middle.
5

Day 5 of 10 · To the turn

The Lower Chain, Southbound

Anchorage: Key West (marina)
The lower chain's refuge water — the run's emptiest, loveliest stretch.
The lower chain's refuge water — the run's emptiest, loveliest stretch.

The second forty-mile leg runs the chain's emptiest miles — wildlife-refuge backcountry, thinning traffic, a final southbound trolling pass — and lands Key West by early afternoon, timed so the group hits Mallory Square's sunset theater on arrival night.

Slip secured for two nights. The turn of the trip gets the town the chain builds toward, starting with Duval Street's opening arguments.

Day Highlights

  • Refuge-water cruising down the lower chain.
  • Mallory Square sunset on arrival.
  • Two-night turnaround begins.

Day 6 of 10 · The turn

Key West in Full

Anchorage: Key West (marina), second night
Old Town at the turn — the lay day the ten-day format buys.
Old Town at the turn — the lay day the ten-day format buys.

The full town day: Hemingway's house and its six-toed staff, the Custom House's salvage-fortune history, the Bight's shrimp-boat waterfront, the galleries and rum rooms of Old Town — all on foot, all inside a mile of the slip. This is the day the ten-day format buys that the seven-day version can't.

The tender adds a harbor-sandbar swim for the restless, and the evening splits between the chef's mid-trip showcase and the town's best rooms. Halfway, and nothing has been rushed yet.

Day Highlights

  • Hemingway to the Bight, all on foot.
  • The lay day only ten days can afford.
  • Chef's mid-trip showcase.

Day 7 of 10 · Northbound

The Return Begins — Same Channel, Different Trip

Anchorage: Marathon (marina)
A Keys sky doing its evening theater — the northbound leg's running backdrop.
A Keys sky doing its evening theater — the northbound leg's running backdrop.

Northbound with the light reversed and the spread rigged for the second pass — the crew fishes the return smarter for what the southbound taught. The lower chain runs by at the same unhurried three hours, and Marathon takes the boat back for a night aimed at whatever the first visit skipped: Pigeon Key under the old bridge, a second reef site, or nothing but the flybridge and a book.

The northbound's quiet argument starts here: weekday-pace towns, no arrival logistics, the chain already familiar enough to enjoy carelessly.

Day Highlights

  • The reef edge fished smarter on pass two.
  • Pigeon Key and the old bridge, if skipped southbound.
  • The chain at weekday pace.
8

Day 8 of 10 · The backcountry day

Islamorada, Second Pass

Anchorage: Islamorada (marina)
Bay-side backcountry — the register the southbound pass saved for the return.
Bay-side backcountry — the register the southbound pass saved for the return.

The return's Islamorada day flips to the bay side: mangrove backcountry by tender, the sandbars at the tide the first pass missed, and for the anglers the flats at dawn — the skiff-and-fly-rod version of the town that the offshore day southbound didn't touch.

It's the ten-day format's thesis in one stop: the same town, twice, without repeating an hour of it. Marina dinner where they already know the group's order.

Day Highlights

  • Dawn flats for the fly rods.
  • Backcountry and sandbars by tender.
  • A town on second-name terms.

Day 9 of 10 · Last full day

Key Largo's Second Reef

Anchorage: Key Largo (marina)
Key Largo's bay side at last light — the trip's second-to-last sunset, dockside.
Key Largo's bay side at last light — the trip's second-to-last sunset, dockside.

The hour north lands the last full day where the chain started, with the reef choice made by conditions instead of schedule — the site the divemaster actually recommends today, not the one the itinerary guessed at last week. The afternoon holds the trip's final swim, final troll, final sandbar hour, in whatever ratio the group votes.

The chef's saved-best closes the evening, and the crew quietly stages the turnaround while the dock lights come on. One easy leg left.

Day Highlights

  • The reef by today's conditions, not last week's plan.
  • Final swim-troll-sandbar ratio, by vote.
  • The chef's closer.

Day 10 of 10 · The run home

Back Up the Channel

Anchorage: —

The morning retraces the first leg in reverse — Hawk Channel north, the skyline lifting ahead, under three hours to the slip. Disembark by early afternoon, under an hour to either airport, with 260 miles of chain run at a pace that never once felt like delivery.

Ten days, one boat, both directions, and the whole argument for doing the Keys properly instead of quickly.

Frequently asked

Why ten days — can't this be done in a week?
It can be attempted in a week; it can't be enjoyed in one. Miami to Key West and back is roughly 260 nautical miles, and a seven-day version either turns around at Marathon without reaching Key West at all, or spends two days running at delivery pace to touch Duval Street and flee. Ten days dissolves the problem: the longest single leg is under three hours, Key West gets two real nights at the turn, and the return trip gains the layover days that make the northbound feel like a second act instead of a rewind. If seven days is truly the constraint, the honest alternatives are the Marathon round-trip or the Miami-to-Key-West one-way — we'll lay out both.
Doesn't the return leg just repeat the same water?
Same channel, different trip — by design. The southbound run spends its afternoons on the headline stops; the northbound return works what got skipped: the bay-side backcountry and sandbars around Islamorada, a second reef site off Key Largo chosen by conditions rather than schedule, the marina towns at weekday pace instead of arrival bustle. Fishing groups get the genuine version of this argument — twenty reef-edge transits instead of ten, with the crew adjusting the spread to what the first pass taught them. Groups for whom any repeated water is dead water should book the one-way instead; that's what it's for.
Why motor yacht only?
The same arithmetic as every Miami-based Keys route, doubled. The Miami–Key Largo and Marathon–Key West legs each run about forty nautical miles — sub-three-hour mornings on a motor yacht, five-to-six-hour days at sailing-cat speed, and this route runs each of them twice. The Florida fleet is overwhelmingly motor yachts anyway; the rare sailing cats in the pool belong on the Key West round-trip, where the single crossing can be given the time it needs. Here, the flybridge is the observation deck and the schedule stays civilized.
When should we book, and what does it cost?
December through April is peak — marina to marina between the cold fronts, with the clear settled days delivering the chain at its winter best. May, June, and November trade a little heat for calmer water and softer rates; July through September is hurricane season with a heat-and-calm problem on top, planned flexibly or planned elsewhere. Ten-day pricing scales from the weekly base — crewed motor yachts here run $25,000 to $150,000+ per week plus expenses — with marina nights and roughly 260 nm of fuel as the honest APA lines. No repositioning fee, no VAT, no cruising tax, no customs anywhere.
