Overview
At the Marathon end of the Old Seven Mile Bridge, this overlook/park doubles as the entrance to a 2.2‑mile, car‑free span toward Pigeon Key. It’s flat, breezy, and instantly scenic—the kind of stop where even a quick leg stretch feels like a mini‑adventure.
What You’ll See
Expect endless water in every direction—turquoise shallows, deep navy channels, and fishing boats sliding beneath the new highway bridge. Look down for sea turtles, rays, sharks, tarpon, and the occasional dolphin; look up for pelicans, great blue herons, ibis, osprey, and other seabirds. Sunrises and sunsets can be outstanding.
How to Visit
- Parking: Roughly 35 spaces at the base; they turn over but fill fast. There’s some overflow across US‑1, connected by a walkway under the highway.
- Path: Paved and flat, open to walkers and cyclists. Posted bike speed is 15 mph; e‑bikes are commonly seen.
- Facilities: No restrooms. About eight picnic tables (including some covered) sit bayside.
- Fishing: Not allowed on the bridge; allowed from the park on the bay side.
- Pigeon Key: A tram runs, and guided tours typically depart mid‑day (often 10 a.m., noon, and 2 p.m.) from the nearby visitor center.
Quick History
Built for Henry Flagler’s Over‑Sea Railroad (1905–1912), the original bridge survived until the 1935 Labor Day hurricane shattered the line. The route was converted to the Overseas Highway in 1938, with rails even reused as guardrails. The modern highway bridge opened alongside the old spans in the late 1970s–early 1980s, and Marathon’s 2.2‑mile Old Seven section reopened to pedestrians and cyclists after restoration in January 2022.
Wildlife Notes
Peer into the clear water with polarized sunglasses to spot stingrays, sharks, sea turtles, schooling fish, and sometimes dolphins. Seabirds patrol the railings and shallows; bring a light zoom if you like bird photos.
Best Time to Visit
Early morning or late afternoon for cooler temps, softer light, and better wildlife viewing. Sunsets are a crowd‑pleaser. There’s little shade, and winds can gust; storms build quickly, so turn back if weather shifts. Parking is easier outside the midday peak, even on weekdays.
Pros
- Car‑free 2.2‑mile old bridge for easy walking and biking
- Big‑sky ocean-and-gulf views with frequent wildlife sightings
Cons

Tips
- Use the under‑highway walkway if you need overflow parking across US‑1.
- Bring water and sun protection—there’s little to no shade.
- Polarized sunglasses make spotting turtles and rays much easier.
- Biking or e‑biking makes the out‑and‑back across the bridge a breeze.
- If visiting Pigeon Key, plan around the typical tram tour times.
