The Keys are the natural next step once a day on Biscayne Bay leaves you wanting more water. From Miami Beach Marina you can point the bow south and trade the sandbar crowd for a chain of islands that runs more than a hundred miles to Key West, with patch-reef snorkeling, quiet overnight anchorages, and a Duval Street sunset at the end of it. This guide covers the route itself: how the run south comes together, realistic run-times, where you stop, and how the overnight option works.
A Keys charter is a multi-day trip, not a day out, so most of the practical planning lives on our multi-day charters page. If you are weighing the Keys against a closer day on the water, our guide to the best yacht routes from Miami lays out the bay routes side by side. Every Keys charter still leaves from Miami Beach Marina with a licensed captain who sets the final route on the day around the weather and the tides.
How a Keys charter from Miami works
Distance is the thing that shapes a Keys run. Key Largo, the first of the Upper Keys, sits a comfortable cruise south of Miami, which makes it the usual first-day target. Key West is the far end of the chain, and reaching it is a serious passage rather than an afternoon’s cruise, which is why a true Miami-to-Key West charter is built around two or three days on the water with overnight stops along the way. Your captain plans the legs around the morning sea state, since the calmer early hours are the best window for the longer open stretches.
As a rough guide, plan on a relaxed first day cruising south into the Upper Keys with a sandbar or reef stop along the way, a middle day working down through Islamorada and the middle Keys, and a final push to Key West if that is the goal. Tell your captain what matters most to you, whether that is snorkeling, a particular island, or simply unhurried time at anchor, and the route gets built around it.
The route south: Miami to the Keys
Day one: Biscayne Bay, Stiltsville, and the run to Key Largo
The first leg eases you out of the city. Leaving Miami Beach Marina you can pass Stiltsville, the cluster of historic stilt houses standing in the flats off Key Biscayne, before the shoreline opens into Biscayne National Park and its patch reefs, some of the closest clear-water snorkeling to Miami. From there it is a steady run south toward Key Largo and the Ocean Reef area, a good place to anchor for the first night.

The Upper Keys: Key Largo and Ocean Reef
Key Largo is where the Keys really begin. The water turns the pale green that the island chain is known for, and the reefs offshore, part of the same system that runs down the coast, are the draw. A morning here might mean snorkeling a patch reef, a swim off the back of the boat, and a slow lunch at anchor before the next leg. The Ocean Reef side is calmer and more private, the kind of anchorage you settle into rather than rush through.

Islamorada and the middle Keys
Continuing south, Islamorada and the middle Keys string together more anchorages, backcountry flats, and dock-and-dine stops where you can pull in for a meal ashore and be back aboard by dusk. This stretch is about the rhythm of the trip more than any single landmark: clear water, easy days, and the sense of the mainland falling away behind you. It is also the natural turnaround point for a shorter two-day Keys charter that does not push all the way to Key West.

Key West: Duval Street and Mallory Square
Key West is the reward at the end of the chain. Arrive by yacht and you get the part most visitors miss: the approach from the water, a berth close to the action, and the option to watch the Mallory Square sunset celebration from your own deck before heading ashore. Duval Street and its bars, galleries, and music are a short walk from the docks, and the next morning you can be back on the water before the day-trippers arrive. Because it sits so far down the chain, Key West is the centerpiece of a three-day charter rather than a quick stop.

Run times and how many days you need
The right length depends on how far down the chain you want to go and how much time you want at anchor versus underway. A two-day charter is enough for the Upper and middle Keys at an easy pace; reaching Key West and back comfortably is a three-day trip. The table below is a planning starting point, not a fixed schedule, since your captain adjusts the legs to the conditions.
| 2-day Keys charter | 3-day Key West charter | |
|---|---|---|
| How far you go | Key Largo through Islamorada | The full chain to Key West and back |
| Pace | One main leg, plenty of time at anchor | Two longer legs, island-hopping |
| What you do | Reef snorkeling, sandbars, dock-and-dine | All of the above plus Key West ashore |
| Overnights | One night at anchor or a marina | Two nights, mixing anchorages and a Key West berth |
| Best for | A first taste of the Keys, longer weekends | The full Keys experience, special occasions |
The overnight option: where you stay
The overnight is what makes a Keys charter different from a day on the bay, and there are two ways to do it. You can anchor out in a calm cove or beside a reef and sleep aboard, which is the quiet, away-from-everything version, or you can take a berth at a marina in the Keys or in Key West when you want to step ashore for dinner and the evening scene. Most three-day trips mix the two: a night at anchor in the Upper Keys, a night on the dock in Key West. Cabins, range, and onboard comfort are what matter for sleeping aboard, so the boat you choose changes the trip more on a multi-day run than it does on a day charter.
Choosing the right yacht for a Keys run
Match the boat to the distance. A Keys or Key West charter needs a yacht with the cabins to sleep your group and the range to cover the longer legs in comfort, which is a different priority than the deck-space-first thinking that suits a sandbar day. A larger motor yacht with proper staterooms earns its keep here. If snorkeling and watersports are central to the trip, ask about a yacht that carries water toys, and see what is available on our water toys page. You can browse the full fleet with capacities and photos on the our yachts page; tell us your group size and how far down the chain you want to go and we will narrow it down.
Keys or Bahamas?
Both are multi-day getaways from Miami, and people often weigh one against the other. The Keys keep you in US waters with no passport or customs stop, a chain of islands you reach by heading south, and a culture-and-reef trip that ends in Key West. The Bahamas is an international crossing of the Gulf Stream to islands like Bimini and Nassau, with bluer water and a true away feeling, and it needs a passport and a customs clearance on arrival. If the Bahamas is what you are picturing, we cover it in full in our guide to planning a multi-day Bahamas charter from Miami.
Planning tips
- Book early for peak season. Keys and Key West charters fill fastest from late fall through spring.
- Build in weather flexibility. The calmer morning hours are best for the longer legs, and your captain plans around the sea state.
- Pack light and smart: swimwear, a towel, reef-safe sunscreen, a layer for the evening, and a US ID for going ashore.
- Leave the provisioning to the crew where you can. Catering, drinks, and other details can be arranged before you board.
- Decide your overnight style up front, anchoring out versus a marina berth, so the route and the boat are matched to it.
Frequently asked questions
How long does a Miami to Key West yacht charter take?
Key West sits at the far end of the island chain, so reaching it comfortably and returning is a three-day charter with two overnight stops. A shorter two-day trip covers the Upper and middle Keys without pushing all the way south.
Can I sail to Key West and back in one day?
No. The distance makes Key West a multi-day trip rather than a day out. For a single day on the water, see our day charter page; for the islands, plan on two to three days.
Where do Keys charters depart from?
From Miami Beach Marina, the same departure point as our day charters. We can also arrange transportation to the marina as an add-on.
Do I need a passport for a Florida Keys charter?
No. The Keys are in US waters, so no passport or customs stop is needed. A passport is only required for an international trip such as the Bahamas.
Where do we sleep on an overnight Keys charter?
Either at anchor in a calm cove or reef, sleeping aboard, or at a marina berth in the Keys or Key West when you want to step ashore. Most three-day trips mix both.
Is the Keys or the Bahamas better from Miami?
The Keys are a passport-free run south through a chain of US islands ending in Key West; the Bahamas is an international crossing to bluer, more remote water. It comes down to whether you want culture and reefs close to home or a true island getaway. Your broker can talk through both.
