Bahia Honda State Park occupies a small island in the lower Florida Keys, roughly 37 miles east of Key West. What sets it apart from other parks in the region is a rare combination: natural sandy beaches, clear warm water with excellent visibility, and the skeletal remains of Henry Flagler’s Overseas Railroad bridge rising above the shoreline. The beaches here have been ranked among the best in the United States, and the surrounding waters support a diversity of marine life that draws snorkelers and divers from around the world.

Beaches and Swimming

The park has three beaches: Sandspur Beach, Calusa Beach, and Loggerhead Beach. Sandspur Beach is the most celebrated, with calm, shallow water and a natural sandy bottom that is uncommon in the Keys, where rocky shorelines are the norm. Calusa Beach sits near the marina and offers views of the old bridge. Swimming is permitted at all three beaches, though lifeguards are not on duty, so visitors swim at their own risk. The water stays warm most of the year, typically ranging from the low 70s Fahrenheit in winter to the upper 80s in summer.

Snorkeling and Marine Life

The reef and nearshore habitats make Bahia Honda one of the better snorkeling destinations in Florida. The park’s concession rents snorkel gear and runs snorkel boat tours to Looe Key Sanctuary Preservation Area within Florida Keys National Marine Sanctuary, a little more than nine miles southwest of Bahia Honda. Visitors can expect to see tropical fish, sea turtles, spotted eagle rays, and coral formations, though recent bleaching and mortality have affected reef conditions. The seagrass beds closer to shore support additional wildlife including conch and various juvenile fish species. For those who prefer to stay above water, fishing and kayak rentals offer other ways to engage with the surrounding ecosystem.

History and the Old Bridge

The Bahia Honda Rail Bridge was part of Flagler’s Overseas Railroad, an engineering achievement completed in 1912 that connected Miami to Key West by rail. The bridge at Bahia Honda required a different design than others along the route because the channel here is deeper, so engineers used steel trusses rather than the concrete arch design used on much of the railway. The railroad ceased operations after the Labor Day Hurricane of 1935 destroyed much of the line. The bridge was later converted for automobile use and served the Overseas Highway until the current bridge opened in 1972. A portion of the old bridge is accessible on foot and provides elevated views of the park and surrounding water.

Camping

The park offers cabins, tent camping, and RV sites across three campground areas. Bayside and some Buttonwood campsites sit along the water and offer views toward the bay side of the island. The Sandspur campground is closest to the best beach. Cabins accommodate up to six people, with the exception of Cabin 2, which accommodates up to four, and all include basic amenities. Camping here is popular year-round and sites fill quickly, especially during winter and spring. Reservations are strongly recommended and can be made through the Florida State Parks reservation system.

Pet Policy

Pets are allowed in the campgrounds and in limited areas of the park grounds but are not permitted in cabins, bathhouses, pavilions, the concession building, on the beaches, or in the water. Where pets are permitted, they must be kept on a six-foot, hand-held leash and be well-behaved at all times. Pets must be vaccinated as required by Florida law, though owners do not need written proof of vaccination when registering to camp. Pets may not be left unattended at campsites.
