Bahia Honda State Park sits at mile marker 37 along the Overseas Highway, where the Atlantic meets the Gulf in the heart of the Florida Keys. Known for its clear waters, sandy beaches, and historic bridges, the park offers a rare slice of natural Keys beauty that’s both accessible and uncrowded—especially by Keys standards.
This 524-acre park on Bahia Honda Key is a favorite for campers, snorkelers, and anyone looking to experience the quieter side of Monroe County. Whether you’re stopping for a swim or settling in for a week under the palms, Bahia Honda delivers the essence of the Lower Keys.
Getting to Bahia Honda State Park
Bahia Honda is roughly 12 miles south of Marathon and about 37 miles north of Key West. The park is easy to spot from the Overseas Highway, with the iconic Bahia Honda Bridge and the remains of the Old Bahia Honda Bridge arching overhead. Parking is available near the entrance, but the lots can fill quickly on weekends and holidays. Entry fees are charged per vehicle, and gates open from 8 a.m. until sundown, 365 days a year.
Given its location in the Lower Keys, Bahia Honda is a practical base for exploring both the Middle and Lower Keys. It’s a natural stop for road trippers or anyone seeking a less-developed alternative to the bustle of Key West.
Beaches and Swimming
Bahia Honda is home to some of the best natural beaches in the Florida Keys, with shallow, sandy entry points rare in the region. Calusa Beach, near the park’s main entrance, offers views of the old bridge and gentle surf—ideal for families and picnics. On the Atlantic side, Sandspur Beach stretches for nearly a mile, with soft sand and turquoise water. (Note: Sandspur Beach is sometimes closed for restoration after storms; check ahead for current conditions.)
Swimming is popular throughout the park, but visitors should be aware that seaweed and seagrass are common, especially after storms. The shallow water makes for safe wading, and the gentle slope is perfect for young children. There are restrooms, showers, and picnic shelters close to the main beach areas.
Snorkeling, Kayaking, and Wildlife
Bahia Honda’s clear waters are a draw for snorkelers and paddlers. The park rents kayaks and snorkeling gear, and guided snorkeling tours (for an additional fee) take visitors to the shallow Looe Key National Marine Sanctuary, about 12 miles offshore. Nearshore snorkeling is also possible right from the beaches, with patch reefs, tropical fish, and the occasional nurse shark or sea turtle.
Birders will find plenty to enjoy, especially during spring and fall migrations. The park’s mix of coastal hammock, tidal lagoons, and sandy shoreline attracts herons, egrets, ospreys, and migratory songbirds. Keep an eye out for Key deer in the early morning or evening hours, especially near the campground.
Camping and Facilities
Bahia Honda State Park is one of the few places in the Keys where you can camp right on the beach. The park offers three campgrounds: Buttonwood (RV and tent, with electric and water), Bayside (tent only, no hookups), and Sandspur (tent and small RVs, when open). Reservations are essential, especially during winter and spring—sites often book up months in advance.
Each campground has restrooms and hot showers. There are also several cabins for rent, perched on stilts with views of the bay. The park store sells snacks, souvenirs, and basic supplies, and there’s a small concession with sandwiches and cold drinks. Note that cell service can be spotty, and there’s no Wi-Fi. Quiet hours are enforced, and generators are not allowed overnight.

History and the Bridges
Bahia Honda’s landscape is shaped by both nature and history. The remains of the Old Bahia Honda Bridge are a reminder of Henry Flagler’s Overseas Railroad, which connected Key West to the mainland in the early 20th century. Today, a short trail leads up to the bridge for panoramic views of the island and turquoise waters below—a popular spot for sunrise and sunset photos.
The park’s visitor center has exhibits on local ecology and railroad history. Interpretive signs throughout the park highlight the role Bahia Honda played in the development of the Florida Keys and Monroe County. The combination of wild shoreline and historic structures gives Bahia Honda a character distinct from other Keys parks.
JJ’s Tip
Arrive early, especially on weekends or during winter high season, to secure parking and snag a good spot on the beach. If you’re camping, bring bug spray—no-see-ums can be fierce at dusk. For the best snorkeling, book a spot on the Looe Key tour, but don’t overlook the shallow patch reefs just offshore from Sandspur Beach when conditions are calm.
Bahia Honda State Park is an essential stop for anyone exploring the Florida Keys. Whether you’re here for a day or a week, the park’s blend of beaches, history, and wildlife offers a genuine taste of the Lower Keys—one that’s increasingly hard to find elsewhere along the Overseas Highway.
