Several rare plants, including yellow satinwood (Zanthoxylum flavum), Florida silver palm (Coccothrinax argentata), Coconut palm (Cocos nucifera), Key thatch palm (Leucothrinax morrisii), and the endangered small-flowered lily-thorn (Catesbaea parviflora) are found in the park Henry Flagler's Florida East Coast Railway once ran through the present parkland to Key West.

In 1908, the Florida East Coast Railway Company built two large two-story dormitories there to house workers building the Bahia Honda Bridge.

A nature trail near the park's oceanside beach skirts a tidal lagoon before passing through a coastal hardwood hammock.

Bicycling and inline skating can be done on the park's 3.5-mile (5.6 km) paved road, and there are several fishing and picnicking spots in the area.

Campsites (primitive and full hook-up) and vacation cabins are available, although reservations for the winter months can be very difficult to get.
