42 Best Sights in The Florida Keys, Florida

For the best view in town, climb the 88 steps to the top of this 1847 lighthouse. The 92-foot structure has a Fresnel lens, which was installed in the 1860s at a cost of $1 million. The keeper lived in the adjacent 1887 clapboard house, which now exhibits vintage photographs, ship models, nautical charts, and artifacts from all along Key West's reefs. A kids' room is stocked with books and toys.

Much of Key West's history, early prosperity, and interesting architecture come from ships that ran aground on its coral reef. Artifacts from the circa-1856 Isaac Allerton, which yielded $150,000 worth of wreckage, comprise the museum portion of this multifaceted attraction. Actors and films add a bit of Disneyesque drama. The final highlight is climbing to the top of the 65-foot lookout tower, a reproduction of the 20 or so towers used by Key West wreckers during the town's salvaging heyday.

Up the road about ½ mile from Long Key State Park, beginning at a close-to-the-ground marker, is a free trail that leads through a tropical-hardwood forest to a rocky Florida Bay shoreline overlooking shallow grass flats. It takes about 20 minutes to walk the ¼-mile route.

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.

A few blocks from the parties of Duval Street lies a purely selfless labor of love: a backyard garden whose paths lead to colorful (and happily squawking) rescued parrots and macaws. Step inside the nondescript side gate, and you'll meet Nancy, an environmental artist, and her flock of feathered children (which you can hold and feed). At 10 am she personally gives a tour, or come between 11 and 3 and do the self-guided version. Bring a lunch and have a picnic in the shade, or just meander and learn. It's Parroting 101, and it might just be the most memorable day of your Key West vacation.

This 84,824-acre refuge was established in 1957 to protect the dwindling population of the Key deer, one of more than 22 animals and plants federally classified as endangered or threatened. The Key deer, which stands about 30 inches at the shoulders and is a subspecies of the Virginia white-tailed deer, once roamed throughout the Lower and Middle Keys, but hunting, destruction of their habitat, and a growing human population caused their numbers to decline to 27 by the middle of the last century. The deer have made a comeback, increasing their numbers to approximately 750. The best place to see them in the refuge is at the end of Key Deer Boulevard and on No Name Key, a sparsely populated island just east of Big Pine Key. Mornings and evenings are the best time to spot them. Deer may turn up along the road at any time of day, so drive slowly. They wander into nearby yards to nibble tender grass and bougainvillea blossoms, but locals do not appreciate tourists driving into their neighborhoods after them. Feeding them is against the law and puts them in danger.

A quarry left over from railroad days, Blue Hole is the largest body of fresh water in the Keys. From the observation platform and nearby walking trail, you might see the resident alligators, turtles, and other wildlife. There are two well-marked trails, recently revamped: the Jack Watson Nature Trail (0.6 miles), named after an environmentalist and the refuge's first warden, and the Fred C. Mannillo Wildlife Trail (0.2 miles), one of the most wheelchair-accessible places to see an unspoiled pine-rockland forest and wetlands. The visitor center has exhibits on Keys biology and ecology. The refuge also provides information on Key West National Wildlife Refuge and Great White Heron National Wildlife Refuge. Accessible only by water, both are popular with kayak outfitters.

There's much to like about this 5-acre island under the Old Seven Mile Bridge. You might even recognize it from a season finale of the TV show The Amazing Race. You can reach it via a restored train that departs from the gift shop, which is in a trailer at Mile Marker 47.5. Once there, tour the island on your own, or join a guided tour to explore the buildings that formed the early-20th-century work camp for the Overseas Railroad, which linked the mainland to Key West in 1912. Later, the island became a fish camp, a state park, and then government-administration headquarters. Exhibits in a small museum recall the history of the Keys, the railroad, and railroad baron Henry M. Flagler. The train ride with tour lasts two hours. Bring your own snorkel gear and dive flag and you can snorkel right from the shore; pack a picnic lunch, too.

Silver-sided tarpon—huge, prehistoric-looking denizens of the not-so-deep—congregate around the docks at this authentic local marina. Children (and many adults) pay $4.50 for a bucket of sardines to feed them and $2.50 each for dock admission. You can also grab a bite to eat indoors or out; shop at a slew of artisans' booths; or charter a boat, kayak, or other watercraft.

Possibly the most photographed site in Key West (even though the actual geographic southernmost point in the continental United States lies across the bay on a naval base, where you see a satellite dish), this is a must-see. Have your picture taken next to the big striped buoy that's been marking the southernmost point in the continental United States since 1983. A plaque next to it honors Cubans who lost their lives trying to escape to America, and other signs tell Key West history.

The second-oldest marine-mammal center in the world doesn't attempt to compete with more modern, more expensive parks. Even so, it's among the better attractions north of Key West, especially if you have kids in tow. In addition to seeing marine-life exhibits and shows, you can make reservations for up-close-and-personal encounters like a swim with a dolphin or sea lion or stingray and turtle feedings (which include general admission). Stop for lunch at the grill, shop in the extensive gift shop, or sunbathe and swim at the private beach.

Each year, more than 100 injured creatures are admitted to the world's first state-certified veterinary hospital for sea turtles. Guided 90-minute tours take you into recovery and surgical areas. In the "hospital bed" tanks, you can see recovering patients and others that are permanent residents due to their injuries. After the tour, you can feed some of the residents. Call ahead—space is limited and tours are sometimes canceled due to medical emergencies. The turtle ambulance out front makes for a memorable souvenir photo.

The fossilized-coral reef, dating back about 125,000 years, demonstrates that the Florida Keys were once beneath the ocean. Excavation of Windley Key's limestone bed by the Florida East Coast Railway exposed the petrified reef, full of beautifully fossilized brain coral and sea ferns. You can see the fossils along a 300-foot quarry wall when hiking the park's three trails.
