The Florida Keys Overseas Heritage Trail offers a challenging hike across a unique coastal landscape. You will traverse 24.8 miles (39.8 km) with a modest 76 feet (23 metres) of elevation gain, requiring an estimated 9 hours and 59 minutes to complete this difficult route. As you hike, expect to be surrounded by the vast expanse of the Atlantic Ocean and the Gulf of Mexico, with views of historic bridges stretching into the horizon. The route connects various islands, providing a continuous journey through a distinct tropical environment. You will experience the constant presence of the sea, with its characteristic breezes and the sight of distant mangroves.

Given the trail's length and exposure, plan your visit carefully. It is essential to carry ample water and sun protection due to the constant Florida sunshine. Parking access points require careful consideration, as this is a long, linear trail that does not loop back. Be aware that some sections of the route may require you to share the path with vehicular traffic, which can be narrow and potentially hazardous. Starting early in the day is advisable to make the most of your time and avoid the midday heat.

This trail is notable for its unique construction, repurposing sections of the historic Overseas Railroad. It offers a rare opportunity to hike directly over the open water, connecting the string of islands that form the Florida Keys. The route provides a distinct perspective on the region's natural beauty and engineering marvels. You will encounter diverse ecosystems, from open ocean views to glimpses of mangrove-fringed shores, making it a truly distinctive experience in the continental United States.
