12 Best Sights in The Florida Keys, Florida

This state park is on everyone's list for easy access to the best diving and snorkeling in Florida. The underwater treasure encompasses 78 nautical square miles of coral reefs and sea-grass beds. It lies adjacent to the Florida Keys National Marine Sanctuary, which contains 40 of the 52 species of coral in the Atlantic Reef System and nearly 600 varieties of fish, from the colorful parrotfish to the demure cocoa damselfish. Whatever you do, get in the water. Snorkeling and diving trips ($39 and $90, respectively; equipment extra) and glass-bottom-boat rides to the reef ($32) are available, weather permitting. One of the most popular snorkel trips is to see Christ of the Deep, the 2-ton underwater statue of Jesus. The park also has nature trails, two man-made beaches, picnic shelters, a snack bar, and a campground. Amenities: food and drink; parking (fee); showers; toilets; water sports.

This Monroe County park, with its groomed pebbly sand, is a popular sunbathing spot.

An athletic trail with 10 fitness stations is also available. Hungry? Grab a bite to eat at Salute!, the on-site restaurant. Across the street, Astro City Playground is popular with young children.

Of Bahia Honda State Park's three beaches, which also include Calusa and Loggerhead, Sandspur is the largest. It's also regularly declared the best beach in the Florida Keys, and you'll be hard pressed to argue. The sand is baby-powder soft, and the aqua water is warm, clear, and shallow. Mild currents here and at the other beaches make them great for swimming, even with small fry. Amenities: food and drink; parking (no fee); showers; toilets; water sports. Best for: snorkeling; swimming.

This wide beach has nearly 1 mile of nice white sand, plus beautiful coconut palms, picnic areas, and volleyball courts, all of which make it popular with the spring-break crowd. Trucks along the road rent rafts, windsurfers, and other beach "toys." Amenities: food and drink; parking; toilets; water sports. Best for: partiers.

One of the best beaches in the Keys has shaded picnic areas overlooking a coconut palm–lined grassy stretch and the Atlantic. Roped-off areas allow swimmers, boaters, and windsurfers to share the narrow cove. Facilities include grills, a large playground, a pier, a volleyball court, and a paved, lighted bike path off the Overseas Highway. Sunday afternoons draw lots of local families toting coolers. The park is accessible for those with disabilities and allows leashed pets. Turn east at the traffic light in Marathon and follow signs to the end; parking is payable at a kiosk with credit card only. Amenities: showers; toilets; parking (paid). Best for: swimming; windsurfing.

On Lower Matecumbe Key this popular village park is named for a local environmental activist. Its "beach" (really a typical Keys-style sand flat with a gentle slope) is best enjoyed at low tide. The nicest feature here is the elevated, wooden, ½-mile boardwalk that meanders through a natural wetland hammock. Covered picnic areas along the way give you places to linger and enjoy the view. Restrooms are at the north end. Weekends are packed with Miami day-trippers as it's the only public beach until you reach Marathon. Amenities: parking (no fee); toilets. Best for: partiers; snorkeling; swimming; windsurfing.

Located at the southernmost point of Bahia Honda State Park, this public beach is a calm and pleasant spot for sunbathing, swimming, and snorkeling. It’s shallow enough for little ones to wade in, and the sand is velvety soft and clean (as opposed to some of the rockier beaches in Key West). There are public restrooms and showers nearby. Camping sites are available, but they tend to book up, so reservations are recommended in high season. Amenities: parking (no fee); showers; toilets; water sports. Best for: swimming; walking.

Next to Louie's Backyard restaurant, this tiny beach—the only one in Key West where dogs are allowed unleashed—has a shore that's a mix of sand and rocks. Amenities: none. Best for: walking.

What is sometimes called “the Oceanside Beach” offers an excellent view of Henry Flagler’s old railroad bridge. A small rock island not far from shore is easy enough to kayak around (rentals are available elsewhere in Bahia Honda State Park), and there are plenty of snorkeling opportunities in the clear waters. This beach doesn't have  picnic pavilions, and its comparative lack of amenities makes it less crowded and more rustic than other park beaches. Amenities: parking (no fee). Best for: solitude; swimming; walking.

This beach and park were named after Cornelius Bradford Harvey, former Key West mayor and commissioner. Adjacent to Higgs Beach, it has half a dozen picnic areas across the street, dunes, a pier, and a wheelchair and bike path. Amenities: none. Best for: walking.
