Pigeon Key sits beneath the Old Seven Mile Bridge off Marathon, roughly an hour north of Key West. This five-acre island served as the base camp for workers building Henry Flagler’s Overseas Railroad between 1908 and 1912, preserving eight historic wooden cottages and a marine research centre. Pigeon Key is worth visiting if you want to explore early twentieth-century railroad history and spot rays in the shallows. Look elsewhere if you require restaurants, lodging, or wide sandy beaches.
