Roadtrippers Plus — Florida Keys Road Trip
US-1 from Miami to Key West has 113 miles, 42 bridges, and dozens of stops most drivers never find.
What the Overseas Highway actually is
US-1 through the Florida Keys is a linear two-lane highway over 42 bridges connecting 30 islands between Homestead and Key West. The structure hides how much is between the keys: the back-country flats at Islamorada where the sea turns flat and green, the Bahia Honda State Park beach that is arguably the best in the Keys and is signed from the road only if you already know to look, the old Seven Mile Bridge pedestrian walkway that most drivers cross at 45 mph without realizing they can walk it. Most people who drive the Keys for the first time arrive in Key West having missed 60% of what made the drive interesting because they were navigating rather than discovering.
What Google Maps misses on US-1
Google Maps will route you from Miami to Key West in 3.5 hours without a wrong turn. What it does not surface is Crane Point Hammock in Marathon — a natural hardwood hammock with the best birding in the Keys, accessible for $15 and easy to miss if you do not know the mile marker. It does not show Anne's Beach at Lower Matecumbe Key, a natural swimming area better than any hotel pool on the island. It does not flag that the only gas stations south of Marathon are sparse and that the fuel estimate for the return trip matters. Roadtrippers surfaces these stops as category-tagged pins before you pass them.
What Plus gives you for the Keys drive
- Unlimited waypoints — plan every key, bridge pullout, state park, and dive site on the full 113-mile route
- Category filters — toggle snorkeling, beaches, nature, food, and camping layers to build your exact trip type
- Fuel cost estimate — coverage is sparse south of Marathon; the estimate flags this before you are running low on Big Pine Key
- Offline mode — cell coverage on some of the longer bridges can drop; download the full US-1 route before you leave Miami
Who this is for
This is for the first-time Keys driver who wants to leave with the feeling of having seen the Keys, not just Key West. It is for anyone spending two or more days on the Overseas Highway — enough time that the intermediate stops matter rather than feel rushed. It is also useful for repeat visitors targeting the Upper Keys specifically: Islamorada and Key Largo are worth a standalone weekend trip and have different stop density than the Lower Keys.
Where to build your route
Start the route at the Florida City entrance to US-1 and add pins at John Pennekamp Coral Reef State Park in Key Largo for snorkeling, Anne's Beach at Lower Matecumbe Key for swimming, Bahia Honda State Park for the beach and nature walk, and the north end of the old Seven Mile Bridge for the pedestrian walkway. Add Robbie's of Islamorada if you want the pelican dock, and plan Key West for a full afternoon rather than a turnaround. That itinerary builds in Roadtrippers in under 20 minutes and would take hours of research to assemble otherwise.
Who should skip it
Skip Roadtrippers Plus for the Keys if you are driving to Key West for a single event and stops are a distraction rather than the point — Google Maps handles that drive fine. Also skip it if you have done the Overseas Highway before and already know your preferred stops by mile marker.
Our take
Buy Roadtrippers Plus before a first-time Florida Keys drive where you want to see the islands, not just arrive at the end of US-1. The route discovery layer and unlimited waypoints transform the Overseas Highway from a corridor you tolerate into the trip itself. Skip it if Key West is the destination and the drive is just transportation.
