Both are expensive, both are famous, and both are in Florida. But that's where the similarities end. Key West and Miami serve completely different travel personalities. Here's the honest comparison.
The Quick Answer
It depends on what you want. Miami is a big-city beach destination — a global city with world-class food, nightlife, and art scenes. Key West is a small island with a quirky, literary character and a focus on slowing down. If you want energy, dining, and culture: Miami. If you want decompression, water activities, and a castaway vibe: Key West.
Vibe Comparison
Miami is urban, fast, and multicultural. South Beach is famous for Art Deco architecture, high-end restaurants, nightclub energy, and a blend of Latin American and Caribbean culture. Wynwood has the art scene — murals, galleries, excellent restaurants. The city is genuinely international. It can feel overwhelming if you're not into crowds and noise. But if you are, Miami has few equals in the US.
Key West is the opposite of urban. The island is 2 miles wide and 4 miles long. Everything is walkable. The pace is slow. The architecture is Conch style. The culture is literary and eccentric — Hemingway, Tennessee Williams, and a long history of writers and artists who came here to be alone. The locals call it the "last resort" — the place where people come to get away from it all. It's small-town in a way that's hard to find anywhere else in America.
Budget Comparison
Miami has a wider range of costs. You can find budget hotels in Miami Beach (outside South Beach), cheap eats in Little Havana, and affordable activities. Or you can spend $500 a night at a South Beach boutique hotel. The spread is wide.
Key West doesn't have a cheap option — everything is expensive because it's an island and everything has to be shipped in. Budget $200+ per night for a mid-range hotel in season. Restaurant meals are $30–60 per person. There's no South Beach equivalent for budget dining. The only real budget option is a VRBO with a kitchen so you can cook some meals.

Beach Comparison
Miami has better ocean beaches — South Beach is iconic (white sand, Atlantic surf, lifeguards, bathrooms), and there are miles of beaches stretching north and south. The water is warm and swimmable. If beach quality is your primary concern, Miami wins.
Key West has much less impressive beaches by traditional sand-and-turquoise standards. The Florida Keys are more about snorkeling and water activities than beach lounging. Fort Zachary Taylor has the best beach on the island — decent sand, clear water — but it's not South Beach. For snorkeling: Key West wins (coral reef, marine life). For swimming in the ocean: Miami wins.
Getting There
Miami is easy — major international airport (MIA) with flights from everywhere, plus Fort Lauderdale (FLL) nearby. You can fly to Miami cheaply from most major cities. Getting around requires a car or rideshare.
Key West is harder. Key West International Airport (EYW) has limited flights — mostly from Miami, Tampa, and Fort Lauderdale on smaller aircraft. You can fly direct from some cities but options are limited. The more common approach: fly into Miami, rent a car, and drive 3.5–4 hours down the Overseas Highway. The drive is part of the trip — don't skip it.
Combined Trip Option: Miami + Key West
The best approach for visitors who can do both: 3 days in Miami, drive down the Keys on day 4, 3 days in Key West. This gives you time in the city and time to decompress on the island. The drive from Miami to Key West (3.5 hours) is scenic — stop at Robbie's of Islamorada (MM 77.5) for the tarpon feeding experience, eat lunch at the Islamorada fish restaurant cluster, and consider a stop at Anne's Beach or Bahia Honda if you have time. Build in these stops and the drive becomes the highlight of the trip.
Who Should Go to Miami Instead
If you want world-class dining and nightlife, international culture, big-city energy, and urban beaches — go to Miami. Wynwood's food scene alone is worth the trip. Art Basel Miami (December) is world-famous. The nightclubs are genuinely world-class. If you're a foodie, an art lover, or someone who thrives on city energy, Miami is the answer.
Who Should Go to Key West Instead
If you want to slow down, disconnect, snorkel, eat fresh seafood, and sit on a porch with a drink watching the sunset — go to Key West. If you want a quirky small-town island with real character and zero corporate chains on the main strip, Key West is the answer. If you're a Hemingway fan, a diving/snorkeling enthusiast, or someone who just needs to get away from it all for a week, Key West is the better choice.
Recommendation
Do both if you can. They're different enough that you're not repeating yourself. Three days in Miami to get the city energy, then a scenic 4-hour drive down the Keys to decompress on an island. That's the trip that will make you want to come back.

Is Key West better than Miami?
Depends entirely on what you want. Miami is a big-city beach destination with world-class dining, nightlife, and art. Key West is a small island with a quirky, literary character and a focus on slow living. Miami is better for culture, dining, and city energy. Key West is better for decompression, snorkeling, and a quirky laid-back vibe. They're both expensive — but for different reasons. There's no 'winner'; there's only the right choice for your trip.
Can you do Miami and Key West in one trip?
Yes — and it's actually a great trip. The drive from Miami to Key West is about 3.5 hours (longer if you stop), and you can do it in a day. The most common approach: 3 days in Miami, drive down the Keys on day 4, 3 days in Key West. This works especially well for visitors flying into Miami. Make sure you have at least one full day in Key West, not just a passing-through night.
How far is Key West from Miami?
Approximately 160 miles by road, following the Overseas Highway (US 1) from Miami to Key West. The drive takes 3.5–4 hours without stops. With stops (Islamorada snorkeling, lunch at Robbie's of Islamorada, Bahia Honda beach break), plan 5–6 hours. The drive itself is scenic — the Keys are unlike anywhere else in the US — so building in stops makes it a better trip.
Is Key West or Miami more expensive?
Both are expensive, in different ways. Miami has expensive hotels and restaurants (especially South Beach) but also has more mid-range options across the city. Key West is smaller and more isolated — everything costs more because it has to be shipped in. Expect high restaurant prices, high accommodation prices, and limited budget options. Key West is marginally more expensive for a comparable level of accommodation, but Miami can get more expensive if you're in South Beach and eating at tourist restaurants.
