Pigeon Key is a historic five-acre island beneath the Old Seven Mile Bridge in Marathon, FL, known for housing Henry Flagler’s railway workers in the early 1900s. Visitors can reach the island on foot, by bike, or by passenger tram from the Pigeon Key Visitors Center, making it a top historic attraction in the Florida Keys.
What Is the History Behind Pigeon Key?
Pigeon Key served as the main construction camp for Henry Flagler’s Florida East Coast Railway Key West Extension from 1908 to 1912.
Long before Pigeon Key became a cherished cultural park, it was an isolated coral island in the middle of the Moser Channel. When industrialist Henry Flagler undertook the monumental task of extending his railroad 128 miles from Homestead to Key West, engineers recognized that this tiny, strategically positioned island was the ideal staging site for building the longest bridge in the entire system: the original Seven Mile Bridge.
Between 1908 and 1912, up to 400 laborers lived on Pigeon Key at once. The island became a bustling, self-contained community with its own post office, commissary, mess hall, power plant, and yellow wooden worker cottages. These bridge builders faced harsh tropical conditions, fierce heat, and relentless mosquitoes as they sank massive concrete piers into the seabed, completing what many at the time called “Flagler’s Folly” or the “Eighth Wonder of the World.”
After the railway opened in 1912, Pigeon Key transitioned into a permanent maintenance hub for railway workers. When the historic 1935 Labor Day Hurricane damaged portions of the track farther north, the Overseas Railway was sold to the State of Florida and converted into the Overseas Highway. Bridge tenders continued living in the historic cottages on Pigeon Key until 1982, when the modern concrete Seven Mile Bridge opened to vehicular traffic alongside the historic span. Today, the island is listed on the National Register of Historic Places and preserved by the non-profit Pigeon Key Foundation, which serves as a living museum dedicated to Marathon, FL’s bold industrial heritage and the Florida Keys.

How Do You Get to Pigeon Key in Marathon, FL?
You can access Pigeon Key by taking the official passenger tram from the Visitors Center, walking, or riding a bicycle along the restored 2.2-mile section of the Old Seven Mile Bridge.
Reaching Pigeon Key is half the adventure. The Pigeon Key Visitors Center, located at 1090 Overseas Highway near Mile Marker 47 on the south end of Marathon, FL, serves as the gateway to the island. From the Visitors Center, travelers have three main ways to make the crossing to the island:
- The Passenger Tram: The Pigeon Key Foundation operates a comfortable, open-air passenger tram that departs several times daily from the Visitors Center at Mile Marker 47. The tram glides high above the water along the historic ramp, offering panoramic views of Florida Bay and the Atlantic Ocean before descending directly onto the island.
- Walking or Running: The first 2.2-mile stretch of the Old Seven Mile Bridge—affectionately known as “Old Seven”—underwent an extensive $44 million restoration and reopened as a wide, safe pedestrian trail. Walking out to the island allows you to move at your own pace, spot sea turtles and rays in the clear water below, and enjoy uninterrupted sea breezes.
- Bicycling: Renting or bringing a bicycle is one of the most popular ways to reach Pigeon Key. Old Seven’s flat, paved surface offers a smooth ride across the water, with designated lanes for pedestrians and cyclists.
If you walk or ride a bike to the island, you can still buy an admission ticket upon arrival on Pigeon Key to enjoy the guided historic tour and museum access. The drive from our private collection of home rentals at Keys Cove at Mile Marker 50 to the Visitors Center takes less than ten minutes, putting you right at the doorstep of this iconic landmark.

How Long Should You Plan to Spend on Pigeon Key?
Most visitors should budget two to three hours to comfortably explore Pigeon Key, take a guided tour, and travel along the Old Seven Mile Bridge.
A well-planned visit allows ample time for both transit and on-island exploration. The passenger tram from the Visitors Center at 1090 Overseas Highway takes about 25 minutes round trip. Guided tours on the island generally last 45 to 60 minutes, leaving you another hour to browse the museum, walk the grounds, take photographs, or relax along the waterfront.
If you walk or bike across the Old Seven Mile Bridge to reach Pigeon Key, budget extra time for the trek across the water. Bicyclists typically take 15 to 20 minutes each way, while pedestrians should allow roughly 45 minutes for the 2.2-mile walk out and another 45 minutes back. Pack water and take short breaks to gaze down at the clear marine channel below.
What Should You Pack and Know Before Visiting Pigeon Key?
Before traveling to Pigeon Key, you should pack sun protection, water, and comfortable walking shoes, as the island is mostly outdoors with limited concessions.
Because Pigeon Key remains a historic sanctuary rather than a commercial development, advance preparation ensures a comfortable day. Here are practical insider tips for making the most of your excursion:
- Sun protection is essential: The walk across the Old Seven Mile Bridge and the island’s open lawns offer very little shade. Bring broad-spectrum sunscreen, polarized sunglasses, and a wide-brimmed hat.
- Hydration and Snacks: The small island shop offers bottled water and light souvenirs, but there are no full-service restaurants or snack bars on Pigeon Key. Pack reusable water bottles and snacks, especially if traveling with kids.
- Footwear: Wear comfortable athletic shoes or sturdy strapped sandals. You will be walking on historic boardwalks, crushed shell paths, and concrete bridge surfaces.
- Camera & Binoculars: The Old Seven Mile Bridge’s elevated span offers some of the best photo opportunities in Marathon, FL. Binoculars are great for spotting seabirds, falcons during fall migration, and marine life near the piers.
- Ticketing & Schedules: Tram seating capacity can fill up during peak winter travel months. Always confirm daily tour departure times online or by phone before heading to the Visitors Center.
