What Makes the Miami to Key West Road Trip Itinerary Worth Doing?
This is one of the few road trips in the U.S. where the drive itself is the destination. The Overseas Highway runs over 42 bridges and passes through a chain of coral islands, giving you open-ocean views on both sides of the road for miles at a stretch [3].
Most road trips reward you at the end. This one rewards you every 20 minutes. Whether you’re into snorkeling, wildlife, local food, or just watching the sun melt into the Gulf of Mexico, the Florida Keys deliver something different at every stop.
Who this trip is for:
- Couples looking for a scenic, low-stress getaway (check out couples trip ideas on Traveeler for more inspiration)
- Families with kids who want hands-on wildlife experiences
- Solo travelers who want a flexible, self-paced adventure
- Anyone who enjoys fresh seafood, warm water, and unhurried days
Who might want to skip it:
- Travelers who dislike driving (there’s no practical alternative between stops)
- Anyone visiting in peak summer without heat tolerance — July and August are hot and humid
Day-by-Day Miami to Key West Road Trip Itinerary
Here’s a practical 4-day breakdown. You can compress it to 3 days or stretch it to 6 if you want more beach time.
Day 1: Miami to Key Largo (MM 126–MM 90)
Start early from Miami — ideally by 8 a.m. — to beat traffic on the Florida Turnpike heading south. Your first major stop is Key Largo, the gateway to the Keys.
Must-do in Key Largo:
- John Pennekamp Coral Reef State Park (MM 102.5): This is the only living coral reef in the continental U.S. [2]. Book a glass-bottom boat tour if you don’t snorkel, or rent gear and get in the water. The reef is genuinely stunning — brain coral, parrotfish, and sea turtles are common sightings [4]. Allow 2–3 hours.
- Robbie’s of Islamorada (MM 77.5): Technically in Islamorada, this is a short drive further south. You can hand-feed massive tarpon from the dock for a few dollars — it’s chaotic, fun, and very Florida Keys [6]. Grab a fish taco from the outdoor market while you’re there.
💡 Local tip: Robbie’s gets crowded after 11 a.m. Arrive right when it opens at 8 a.m. for a quieter experience and calmer tarpon.
Day 2: Islamorada to Marathon (MM 90–MM 50)
Islamorada calls itself the “Sport Fishing Capital of the World.” Even if fishing isn’t your thing, the sunsets here are exceptional.
Key stops:
- Lignumvitae Key Botanical State Park: Accessible only by boat, this island has virgin tropical hardwood hammocks that haven’t been logged or developed [1]. Robbie’s Marina runs boat tours there. It’s one of the most underrated stops on the entire route.
- What The Fish Rolls & More: A local seafood shack beloved for fresh fish rolls and conch fritters. Simple, cheap, and genuinely good [6].
- Dolphin Research Center (Grassy Key, MM 59): A non-profit facility focused on rescue and education, connected to the original “Flipper” family [5]. You can watch training sessions and learn about dolphin behavior without the commercial-park vibe [6].
- The Turtle Hospital (Marathon, MM 48.5): One of the most memorable stops on the whole drive. You’ll meet resident sea turtles being rehabilitated from injuries and illness [4]. Tours run several times a day and last about 90 minutes. Book ahead — spots fill up fast [6].
Day 3: Big Pine Key & Bahia Honda (MM 50–MM 33)
This stretch is quieter and less touristy, which is exactly why it’s worth slowing down for.
Key stops:
- Bahia Honda State Park (MM 37): The beach here — Sandspur Beach — has the kind of turquoise water you’d expect in the Caribbean, not Florida [1]. Swim, kayak, or just sit and watch the pelicans. Sunset from the old bridge ruins is spectacular.
- National Key Deer Refuge (Big Pine Key, MM 30): Follow signs to the Blue Hole, a former quarry that’s now a freshwater pond surrounded by mangroves [4]. Walk the short loop trail and you’ll likely spot key deer (they’re tiny — about the size of a large dog), turtles, and sometimes alligators [5].
- No Name Pub (Big Pine Key): This is the hidden gem locals love. A no-frills bar covered floor-to-ceiling in signed dollar bills, serving cold beer and some of the best pizza in the Keys [6]. It’s genuinely hard to find — that’s part of the charm. Search the address before you go.
Day 4: The Seven Mile Bridge to Key West (MM 47–MM 0)
The Seven Mile Bridge is the centerpiece of the entire Miami to Key West road trip itinerary. Driving across it feels surreal — open ocean on both sides, the old bridge running parallel, and nothing but water to the horizon [6][7]. Pull over at the rest area on the Knight’s Key side for photos before you cross.
In Key West:
- Ernest Hemingway Home & Museum: Hemingway lived here for a decade. The house is beautiful, the six-toed cats are everywhere, and the garden is genuinely peaceful.
- Southernmost Point Buoy: The famous red, black, and yellow marker at the southernmost tip of the continental U.S. The line for photos can be long — go early morning.
- Fort Zachary Taylor Historic State Park: The best beach in Key West, with clear water and far fewer crowds than Smathers Beach.
- Duval Street at sunset: Walk it, grab a drink, and watch the street performers. It’s touristy but worth one evening.

What Are the Best Hidden Stops on the Miami to Key West Road Trip Itinerary?
Beyond the well-known attractions, several stops consistently surprise first-time visitors. These are the places locals recommend and guidebooks often skip.
| Hidden Stop | Location (MM) | Why It’s Special |
|---|---|---|
| No Name Pub | Big Pine Key, MM 30 | Dollar-bill-covered walls, great pizza, zero tourists |
| Blue Hole Trail | Big Pine Key, MM 30 | Freshwater pond with key deer and alligators |
| Lignumvitae Key | Accessible from MM 77.5 | Untouched tropical forest, boat-access only |
| Anne’s Beach | Islamorada, MM 73.5 | Free, quiet, shallow swimming beach |
| Crane Point Hammock | Marathon, MM 50 | Nature trails through original Keys habitat |
Anne’s Beach deserves a special mention. It’s a free public beach in Islamorada with a short boardwalk through mangroves and shallow, calm water perfect for kids. On a weekday, you might have it nearly to yourself.
Where to Stay Along the Miami to Key West Route
Accommodation along the Overseas Highway ranges from budget-friendly motels to waterfront resorts. Book early — especially for weekends and holiday periods, when availability drops fast.
Key Largo
- Kona Kai Resort & Gallery: A small, adults-only boutique resort on a private beach. Lush tropical gardens, kayaks included, and a genuinely relaxed atmosphere. Mid-to-high range.
- Largo Resort: Good value for families, with direct bay access and a boat ramp.
Islamorada
- Cheeca Lodge & Spa: The most iconic resort in Islamorada. Oceanfront, full-service, with its own fishing pier and beach. Expensive but worth it for a splurge night.
- Postcard Inn Beach Resort: More affordable, right on the ocean, with a lively tiki bar.
Marathon
- Tranquility Bay Beach House Resort: Overwater bungalows and beach houses on a private beach. One of the most unique stays in the Keys.
- Banana Bay Resort & Marina: Solid mid-range option with a pool, marina, and easy access to the Turtle Hospital.
Big Pine Key
- Deer Run Bed & Breakfast: A small, eco-friendly B&B right on the ocean. Solar-powered, adults-only, and surrounded by key deer. One of the most peaceful stays on the route.
Key West
- The Gardens Hotel: A historic boutique hotel in Old Town, set in a lush tropical garden. Quiet, elegant, and walking distance to everything.
- Curry Mansion Inn: A Victorian-era mansion turned B&B with a heated pool and full breakfast. Great location on Caroline Street.
- Southernmost Beach Resort: For those who want a beach right in Key West, this is the best option — oceanfront rooms and a pool overlooking the Atlantic.
💡 Booking tip: If you’re traveling in March or April (peak season), book accommodation at least 6–8 weeks in advance. The Keys have limited rooms and prices spike significantly during spring break.
How Long Should You Spend on This Road Trip?
Three days is the minimum to do the route justice. Four to five days is the sweet spot for most travelers. Six days or more suits those who want to dive, fish, or simply linger.
Quick planning guide:
- 3 days: Miami → Key Largo → Marathon → Key West. You’ll hit the highlights but move fast.
- 4 days: Add Islamorada and Big Pine Key stops. Much more comfortable pacing.
- 5–6 days: Add boat trips, snorkeling excursions, fishing, and real beach time.
If you’re planning other U.S. road trips, our California 10-day coastal road trip itinerary is another excellent option for a longer self-drive adventure.
What Should You Eat and Drink Along the Way?
The Florida Keys have a distinct food culture built around fresh seafood, Cuban influence, and a few legendary local dishes. Don’t skip these:
- Key lime pie: The real version uses actual Key limes, has a graham cracker crust, and is dense and tart — not sweet. Try it at multiple spots and compare. Kermit’s Key West Key Lime Shoppe is a classic stop.
- Conch fritters: A Keys staple. Look for them at local shacks rather than sit-down restaurants for the best versions.
- Fresh fish sandwiches: Mahi-mahi, grouper, and yellowtail snapper are all caught locally. “What The Fish Rolls & More” in Islamorada is a standout [6].
- Stone crab claws: In season from October to May. Order them chilled with mustard sauce.
- Cuban coffee: The Miami influence follows you all the way down US-1. Strong, sweet, and essential for early mornings.
Practical Tips for Driving the Overseas Highway
A few things that make the drive smoother:
- Fill up your tank in Florida City before crossing onto the Keys. Gas stations exist along the route but prices are noticeably higher once you’re on the islands.
- Mile Markers (MM) are your navigation system. Addresses on the Keys use MM numbers rather than street addresses. MM 126 is Key Largo; MM 0 is Key West [3].
- Traffic on US-1 is single-lane in most places. Passing is limited, and you’ll often end up behind slow-moving vehicles. Build extra time into your schedule.
- Sunrise vs. sunset: The Atlantic side (ocean side) faces east — great for sunrise. The Gulf side faces west — better for sunset. Most of the best sunset spots are on the Gulf side.
- Wildlife on the road: Key deer cross US-1 on Big Pine Key, especially at dawn and dusk. Slow down through that area.
