Key West Trip Planning Guide: Everything You Need to Know

Key West sits at the end of a 113-mile chain of islands off the southern tip of Florida, closer to Havana than to Miami. It's a small town with a big personality: literary history, reef diving, sunset rituals, and a general refusal to take itself too seriously. Planning a trip there is straightforward once you know a few things that first-timers usually learn the hard way.

When to Go

The best weather in Key West runs from mid-November through April. Temperatures sit in the low 70s to low 80s, the humidity is manageable, and rain is relatively rare. This is also the busiest and most expensive stretch, particularly around Christmas, New Year's, and spring break.

May through June is underrated. The weather is warm but not brutal, crowds are thinner, and prices drop noticeably. Hurricane season runs June through November, with the peak in September. That doesn't mean you can't travel then, just watch the forecast and make sure you have flexible bookings.

Fantasy Fest in late October is a famously wild adults-only festival that takes over the island for ten days. If that's your scene, book six months out. If it's not your scene, avoid that window entirely.

How to Get There

You have two realistic options: fly or drive.

Key West International Airport (EYW) has direct flights from Miami, Fort Lauderdale, Atlanta, Charlotte, and a handful of other cities. The flights from Miami are under 45 minutes. This is the most convenient option if you're coming from outside Florida.

Driving the Overseas Highway (US-1) from Miami takes about three and a half hours without traffic. The drive itself is genuinely beautiful, especially the Seven Mile Bridge stretch. Stop in Islamorada for lunch. Rent a convertible if the budget allows.

Once you're in Key West, the island is small enough to navigate by bike or scooter. Parking is expensive and scarce. Most visitors rent a bicycle for the week and leave the car at the hotel.

Where to Stay

Old Town is where you want to be. It puts you within walking distance of Duval Street, the waterfront, and most of the island's best restaurants. It's also the most expensive zone. The closer you are to the southern end of Duval, the higher the price.

The guesthouses on quiet side streets in Old Town offer a better experience than the big chain hotels at a fraction of the price. Look at properties on Simonton, Fleming, and William Streets. Many are in historic Conch houses with small courtyards and pools.

New Town, east of White Street, is more affordable and has a few good options if you're on a budget. It's a quick bike ride to Old Town, so you won't feel cut off.

What to Do

Sunset at Mallory Square

Every evening, the crowd gathers at Mallory Square on the waterfront to watch the sun drop into the Gulf of Mexico. Street performers, food vendors, and a spontaneous festive atmosphere make it more than just a sunset. Arrive 30 to 45 minutes early for a good spot.

Snorkeling and Diving

Key West sits adjacent to the Florida Reef, the third-largest coral reef in the world. Snorkel trips run daily from the Historic Seaport and take you to shallow reef systems teeming with tropical fish. Half-day snorkel tours run around $45 to $60 per person. Scuba divers should look at trips to the Vandenberg, a 523-foot decommissioned military ship sunk as an artificial reef in 2009. It's one of the largest artificial reefs in the world.

Dry Tortugas National Park

This is the best day trip from Key West and genuinely one of the most impressive things in the Florida Keys. The Dry Tortugas are a cluster of seven islands 70 miles west of Key West, accessible only by boat or seaplane. The centerpiece is Fort Jefferson, a 19th-century hexagonal fort that covers most of Garden Key. The snorkeling around the fort is exceptional: clear, shallow water with healthy coral and fish. The Yankee Freedom ferry runs daily and takes about two and a half hours each way. Book it early; it sells out weeks in advance during peak season.

Duval Street and the Food Scene

Duval Street is the main drag and it caters hard to tourists, which means you should walk it, see the scene, and then spend most of your meals elsewhere. Blue Heaven in Bahama Village is a legendary spot for brunch. Garbo's Grill, a food truck near the Historic Seaport, makes one of the better lobster reubens you'll find. For key lime pie, the original and still the best argument is either Kermit's or the Blond Giraffe, and locals will fight you over which is correct.

Ernest Hemingway Home

Hemingway lived in Key West from 1931 to 1939 and wrote some of his most important work here, including "A Farewell to Arms." The house is a museum now, open daily, and the tour is worth the $18 admission. The descendants of his six-toed cats still live on the property. There are currently about 60 of them.

Practical Notes

Key West is genuinely easy to enjoy, but a few things help: bring cash for the smaller food vendors, sunscreen in industrial quantities, and realistic expectations about Duval Street after 10pm (it becomes a party strip). Book the Dry Tortugas ferry and any popular water tours as early as possible.
