How to Ride the Florida Keys Overseas Heritage Trail on an Ebike

Florida is called the Sunshine State for a reason: warm weather nearly year-round, turquoise water, abundant wildlife, and some of the best seafood in the country. But one part of Florida life that doesn't get talked about enough is its biking scene.

Florida is home to some of the most scenic tropical rides in the United States, and none is more iconic than the Florida Keys Overseas Heritage Trail, a 106-mile route that hops from island to island across historic railroad bridges, with open water on both sides. Even better, it's ebike-friendly.

In this guide, we'll cover the trail's best sections, the stops worth pulling over for, how to handle the Keys' heat and weather, Florida's ebike rules, and how to choose the right ebike for the ride.

What are the Florida Keys?

The Florida Keys are a chain of coral and limestone islands that curve southwest from the tip of the Florida mainland, separating the Atlantic Ocean from Florida Bay and the Gulf. The Overseas Highway (U.S. 1) links them for more than 100 miles, from Key Largo all the way to Key West, the southernmost city in the continental United States.

The Keys are commonly divided into five regions, each with its own personality:

• Key Largo: The gateway to the Keys and the "Dive Capital of the World," home to the first undersea park in the U.S.
• Islamorada: The "Sport Fishing Capital of the World," known for its marinas, art galleries, and laid-back village feel.
• Marathon: The heart of the Middle Keys, with family-friendly beaches, a sea turtle hospital, and the famous Seven Mile Bridge.
• Big Pine Key and the Lower Keys: Quiet, natural, and home to the endangered Key deer.
• Key West: Colorful, historic, and lively, where Ernest Hemingway once lived and the sunset celebrations are legendary.

If you love the water, wildlife, and wide-open views, the Keys belong on your travel list. And if you love to ride, there's no better way to see them.

The Florida Keys Overseas Heritage Trail at a Glance

The Florida Keys Overseas Heritage Trail (FKOHT) is a multi-use path managed by Florida State Parks. It follows the route of Henry Flagler's Florida East Coast Railway, once nicknamed the "Eighth Wonder of the World," and today runs alongside U.S. 1, a designated National Scenic Highway and All-American Road.

Good to know before you go: The trail isn't fully continuous yet. Hurricanes have damaged several sections and historic bridges over the years, and repairs are ongoing. In some stretches, especially in the Lower Keys, you'll need to ride in the U.S. 1 bike lane or on the road shoulder alongside fast traffic. There's good news, too: the restored Ohio-Missouri Bridge near Sunshine Key reopened to walkers and cyclists in fall 2026. Before you ride, check the "Know Before You Go" alerts on the Florida State Parks trail page for the latest closures.

The Best Sections of the Trail to Ride

You don't have to ride all 106 miles to experience the magic. If you only have a day or two, these sections offer the best mix of views, safety, and things to do. Locations in the Keys are given by mile marker (MM), the small green signs along U.S. 1.

Old Seven Mile Bridge and Pigeon Key (Marathon, MM 47)

This is the ride most people picture when they think of biking the Keys. The historic "Old Seven" Mile Bridge reopened to walkers and cyclists in 2022 after a multi-year restoration, and its 2.2-mile, car-free span delivers nonstop ocean views and some of the best sunrises and sunsets in Florida.

At the end of the bridge is Pigeon Key, a tiny island that housed around 400 workers who built the railroad in the early 1900s. Today it's a historic district with a museum and shaded picnic spots. Admission is required to visit the island, which is open during the day, so check hours before you go.

Make it a longer ride: Continue north on the trail for about three miles and follow the dedicated bike path to Sombrero Beach (MM 50), a free local beach with restrooms, picnic tables, and calm water for swimming and snorkeling.

Tip: The bridge is popular and parking at the MM 47 lot fills quickly, so arrive early.

Long Key Bridge (MM 71 to MM 62)

The historic Long Key Bridge is the second-longest bridge of Flagler's railroad and is preserved as a smooth, traffic-free path running beside the modern highway. Start from the Channel 5 Bridge area (MM 71) for an approximately 18-mile round trip, or park at the southern end of the Long Key Bridge (MM 65.6) for a shorter out-and-back on the bridge itself.

Along the way, you'll pass Long Key State Park, a peaceful spot with nature trails and mangrove-lined shoreline.

Tip: The trail near Long Key State Park can flood after heavy rain, and the Channel 5 area has seen construction and repair closures in late 2026. Check the latest trail alerts before you start.

Islamorada's Old Road (MM 90 to MM 80)

For a slower, more local ride, follow the quiet residential Old Road through Islamorada. It's about 10 miles one way, with shady stretches and occasional water views. Stops along the way include the Hurricane Monument (MM 81.5), which honors the victims of the 1935 Labor Day Hurricane, plus local galleries, marinas, and waterfront restaurants.

Don't miss Robbie's of Islamorada, where you can hand-feed the giant tarpon that gather at the docks.

Key Largo to Islamorada (MM 106 to MM 72)

This is the longest continuous paved section of the trail, separated from the highway for most of its length. It's more wooded than scenic, but it's a great choice if you want to rack up miles safely. Plan a stop at John Pennekamp Coral Reef State Park (MM 102.5), where you can snorkel, kayak, or take a glass-bottom boat tour over the reef.

Lower Keys to Key West (MM 15 to MM 0)

This stretch has a dedicated trail lane on the ocean side, several trail bridges, and long, open water views as you approach the end of the road. Refuel at the coffee shops and cafes along the way, and make time for the Key West Tropical Forest & Botanical Garden on Stock Island.

Once you roll into Key West, the town is compact and easy to explore by bike. Snap a photo at the Southernmost Point buoy, visit the Ernest Hemingway Home and Museum, cool off at Fort Zachary Taylor Historic State Park, and finish your day at the sunset celebration at Mallory Square.

Tip: Some Lower Keys bridges are still being rebuilt after hurricane damage, so expect to use the U.S. 1 bike lane in places.

More Sights to See Along the Way

• Bahia Honda State Park (MM 37): Known for some of the most beautiful beaches in the Keys. Walk up to the old Bahia Honda rail bridge for one of the best views in the island chain.
• National Key Deer Refuge (Big Pine Key): Spot the tiny, endangered Key deer and stop at the Blue Hole, a freshwater pond that's home to turtles, fish, and wading birds. Please don't feed the deer, and ride slowly in the area.
• The Turtle Hospital (Marathon): Take a guided tour of this rescue and rehabilitation center for injured sea turtles.
• Crane Point Hammock (Marathon): A 63-acre nature preserve with trails, a museum, and a wild bird center.
• Curry Hammock State Park (Marathon): A quiet beach and one of the best spots in the Keys for kayaking and paddleboarding.
• Grassy Key: Ride through mangroves alive with birds and wildlife, and stop at the Dolphin Research Center to learn about marine mammals.
• Everglades and Biscayne National Parks: If you're driving down from Miami, you'll pass near both national parks. The Everglades' Shark Valley has a popular paved loop for cyclists. Just be sure to review the park rules before you bring your ebike.

How to Plan a Multi-Day Ebike Trip Through the Keys

Want to ride the whole thing? Most riders split the trip into three or four days, with overnight stops along the way. Here's a sample plan:

• Day 1: Key Largo to Islamorada (about 25 miles). Start with the longest paved section, and stop at John Pennekamp to snorkel.
• Day 2: Islamorada to Marathon (about 35 miles). Ride the Old Road, cross the Long Key Bridge, and catch sunset on the Old Seven Mile Bridge.
• Day 3: Marathon to Big Pine Key (about 20 miles). Visit Pigeon Key in the morning, then spend the afternoon at Bahia Honda State Park.
• Day 4: Big Pine Key to Key West (about 30 miles). Look for Key deer, then roll into Key West in time for the Mallory Square sunset.

Planning tips:

• Ride southbound. Prevailing winds usually make the southbound trip easier than heading north.
• Book lodging early, especially during the winter high season.
• Know your crossings. The modern Seven Mile Bridge has only a shoulder next to high-speed traffic. If you're not comfortable riding it, local taxis and shuttles with bike racks can carry you across.
• Plan your return. Buses connect Key West back up the Keys, but bike space can be limited, so arrange transportation in advance.

Florida Keys Biking Tips: Beat the Heat, Sun, and Storms

The Keys are farther south than any other part of the continental U.S., so expect stronger sun, higher humidity, and more heat than you might be used to, even in winter. A little preparation goes a long way.

Hydrate, Hydrate, Hydrate!

Heat and exercise are the two biggest drivers of sweat, and the Keys' humidity makes it worse. The more you sweat, the more fluids you lose. If you don't replace them, you risk exhaustion, heat cramps, and heatstroke.

Start your ride hydrated, drink regularly before you feel thirsty, and consider electrolytes on longer days. Bring a water bottle (or three), and refill whenever you pass a cafe or park.

Protect Yourself From the Sun

Much of the trail, especially on the long bridges, has no shade. Too much sun can quickly lead to sunburn, fatigue, and dehydration, and over time it raises your risk of skin damage and skin cancer.

Apply a reef-safe, water-resistant sunscreen generously and reapply often. Wear UV-protective clothing, sunglasses, and a helmet with a visor, and plan breaks in the shade. Riding early in the morning or late in the afternoon also helps you avoid the strongest midday sun.

Watch the Weather

Summer in the Keys brings frequent afternoon thunderstorms. They're usually short, but they can bring lightning, strong winds, and heavy downpours, and the long bridges offer no shelter. Check the forecast, plan to finish longer rides before mid-afternoon, and get off the bridges if a storm rolls in.

Atlantic hurricane season runs from June 1 to November 30. If you're traveling during those months, keep an eye on tropical forecasts and follow local guidance.

Respect Wildlife and Fellow Trail Users

The trail is shared with walkers, runners, and anglers fishing from the historic bridges. Slow down when passing, announce yourself with a bell or a friendly "on your left," and give fishing lines plenty of room. Stay on the trail to protect fragile mangroves and nesting areas.

Tips for Riding the Keys on an Ebike

An ebike is a huge advantage in the Keys. Pedal assist and a throttle help you push through headwinds, cover long distances in the heat, and save energy for exploring once you arrive. A few things to keep in mind:

• Plan your range. Headwinds, heat, and heavier loads can reduce your battery range. For multi-day trips, charge every night, and consider a spare battery for longer days.
• Keep your battery cool. Don't leave your battery in direct sun or a hot car for long periods, and charge it indoors at room temperature when you can.
• Rinse off the salt. Salt air and spray can corrode components over time. After your trip, gently wipe or rinse your bike with fresh water (avoid high-pressure sprays on electrical parts), dry it, and re-lube the chain.
• Prepare for flats. Road debris is common along the highway shoulder. Puncture-resistant tires, a patch kit, and a mini pump are worth packing.
• Know the rules. Florida uses the three-class ebike system and treats ebikes much like traditional bicycles, so you don't need a license or registration. Riders under 16 must wear a helmet, and cities, counties, and parks can set their own local rules. Read our Florida ebike laws guide for the details.
