Drive the Overseas Highway and Stop at Seven Mile Bridge

When you’re planning your first trip to the Florida Keys, driving the legendary Overseas Highway should top your must-do list. This 113-mile stretch of US Route 1 takes you across 42 bridges connecting stunning islands from Key Largo to Key West.

You’ll experience the famous “highway that goes to sea” with ocean views on both sides.

Make Seven Mile Bridge your essential photo stop. This engineering marvel offers unobstructed turquoise water views and ranks among the world’s most scenic drives.

Don’t rush—stick to the 45-55 mph speed limits and expect 3-4 hours from Miami to Key West.

Traffic gets heavy on weekends and holidays, so plan accordingly. The route follows the path of the historic Overseas Railroad, which was destroyed in the devastating 1935 Labor Day hurricane and later converted into today’s scenic highway.

The mile marker system starts at Mile 0 in Key West, increasing as you head northeast.

Snorkel the Living Coral Reef at John Pennekamp State Park

After you’ve conquered the Overseas Highway, you’ll want to learn about the Florida Keys’ underwater world at John Pennekamp Coral Reef State Park in Key Largo. This first undersea park protects America’s only living coral reef system in the continental US, hosting over 30 coral species and 500+ fish varieties.

Book a guided snorkeling tour to reach the best offshore reefs—you can’t access them from shore. You’ll spot colorful brain and star corals, angelfish, parrotfish, and sea fans in crystal-clear waters.

For budget-friendly practice, try Cannon Beach’s shallow snorkeling over seagrass beds and historic shipwreck artifacts.

Visit the center’s aquariums first to identify species you’ll encounter. The park spans approximately 178 nautical square miles of protected marine habitat, ensuring abundant wildlife viewing opportunities. Tours typically cost $30-40 per person, making this incredible biodiversity surprisingly accessible.

Visit the Hemingway House and Meet the Six-Toed Cats

Step into literary history at 907 Whitehead Street, where Ernest Hemingway’s Spanish Colonial home draws more visitors than any other Key West attraction. Built in 1851 from native limestone, this two-story house served as Hemingway’s residence from 1931-1940, his most productive writing period.

You’ll explore rooms filled with original furnishings and peek into his preserved writing studio, complete with vintage Underwood typewriter.

The real stars? Approximately 50-60 cats roaming the property, about half sporting six toes—descendants of Hemingway’s original polydactyl cat. These famous felines, named after celebrities and literary figures, freely wander the lush tropical gardens. The cats even have their own cemetery in the house’s garden for those who have passed away.

Don’t miss the swimming pool where Hemingway embedded his “last penny” into the patio, joking about the $20,000 construction cost.

Catch the Sunset Celebration at Mallory Square

From Hemingway’s literary legacy, you’ll want to time your evening around Key West’s most beloved daily ritual. The Sunset Celebration at Mallory Square has drawn crowds since the 1970s, transforming nightly into a waterfront festival two hours before sunset.

Arrive 60-90 minutes early to claim your spot along the seawall facing west over the Gulf of Mexico. You’ll find street performers creating entertainment circles—magicians, jugglers, sword swallowers, and occasionally trained cats performing tricks.

Local artists sell handmade jewelry, paintings, and souvenirs throughout the open concrete plaza. The atmosphere comes alive with island-flavored music from singer-songwriters and guitarists providing the perfect soundtrack to the evening.

The celebration builds to a collective cheer as the sun disappears into the horizon. It’s free entertainment with harbor breezes and unobstructed sky views, making it Key West’s most popular tourist attraction and perfect budget-friendly evening activity.

Spend a Day at Bahia Honda State Park Beach

Why settle for crowded resort beaches when you can experience one of Florida’s most pristine stretches of sand just 32 miles from Key West? Bahia Honda State Park delivers crystal-clear turquoise waters and natural sandy beaches that consistently rank among America’s best.

You’ll find three distinct beaches across 500 acres. Hit Sandspur and Loggerhead on the Atlantic side for classic beach vibes, or choose Calusa Beach on Florida Bay for snorkeling among sea grass beds. The shallow, calm waters are perfect for families.

Don’t miss climbing the historic rail bridge remnant for panoramic views. The original bridge was built by Henry Flagler and replaced in 1938, creating this unique vantage point. At $8 per vehicle, you’ll get restrooms, showers, picnic areas, and equipment rentals. The park’s open 8 a.m. to sunset daily, making it an affordable full-day adventure.

Take a Behind-the-Scenes Tour at the Turtle Hospital

After soaking up sun and sand, head 45 minutes northeast to Marathon for an eye-opening experience at the Turtle Hospital, where you’ll go behind the scenes of one of the world’s first sea turtle rehabilitation facilities.

Your 90-minute guided tour starts with a classroom presentation covering sea turtle biology and threats like boat strikes and plastic ingestion. You’ll then walk through actual treatment areas, including the emergency room and operating room where staff perform tumor removals and shell repairs.

The outdoor rehab tanks showcase turtles at various recovery stages. Founded by former Volkswagen repairman Richie Moretti over 30 years ago, this facility has successfully saved more than 1,500 sea turtles from death.

The tour concludes with feeding permanent residents – an unforgettable hands-on experience. At $35 for adults and $17.50 for kids, advance reservations are essential since tours run every 30 minutes from 9 a.m. to 4 p.m. Your admission directly supports this essential conservation work.

Go Sport Fishing in Islamorada’s Legendary Waters

While Marathon showcases the Keys’ conservation efforts, Islamorada reveals why anglers worldwide consider it the “Sport Fishing Capital of the World.” You’ll discover an angler’s paradise where the Gulf Stream’s proximity, extensive coral reefs, and vast Florida Bay backcountry create ideal conditions for both offshore and inshore fishing.

Book half-day charters for budget-friendly reef fishing targeting snapper and grouper, or splurge on full-day offshore trips chasing sailfish, mahi-mahi, and wahoo.

If you’re seeking iconic experiences, try flats fishing for tarpon, bonefish, and permit using sight fishing techniques. Winter cold fronts actually concentrate fish populations, making this an excellent time to target species in both shallow flats and deeper offshore waters.

Prime spots include the Islamorada Hump for blackfin tuna and local bridges during tide changes for tarpon and snook.

Whether you’re trolling offshore waters or sight fishing shallow flats, Islamorada’s legendary waters deliver unforgettable angling adventures.

Explore the Underwater World at Christ of the Deep

Just six miles offshore from Key Largo, you’ll discover one of the world’s most iconic underwater monuments at Christ of the Deep. This 9-foot bronze statue of Christ with uplifted arms sits in just 25 feet of water, making it perfect for both snorkelers and beginner divers.

You’ll reach the site via commercial boat tours from Key Largo marinas – the most budget-friendly option for first-time visitors. The statue’s hands rest only 11 feet below the surface, so you won’t need advanced diving skills to get close-up photos.

Beyond the statue itself, you’ll encounter vibrant coral reefs teeming with parrotfish, angelfish, and rays. The site’s shallow depth and typically clear visibility make it an ideal introduction to the Florida Keys’ underwater world. Look for Spotted Eagle Rays gliding gracefully around the sandy areas that surround the reef.

Kayak Through Mangrove Tunnels in the Backcountry

Beyond the coral reefs, you’ll find some of the Keys’ most peaceful adventures winding through backcountry mangrove tunnels. These shallow, protected waterways create natural “tunnels” where arching mangrove roots form overhead canopies, perfect for beginners.

You’ll paddle through 1-4 feet of calm water while spotting manatees, nurse sharks, and tropical fish in their nursery habitat.

Popular spots include John Pennekamp’s marked trails in Key Largo and Curry Hammock’s 1.2-mile loop near Marathon. The experience offers a wilderness feel far from civilization, with pristine ecosystems rich with blue herons, egrets, and pelicans.

Guided tours (2-3 hours, small groups) include equipment and expert interpretation of mangrove ecology, though self-guided options exist at several state parks.

Launch points span from Key Largo to Key West, with many offering free public access and trail maps.

Get Your Photo at the Southernmost Point in the Continental US

Since you’ve made it this far south, you’ll want to snap the quintessential Florida Keys photo at the Southernmost Point marker in Key West. This 12-foot concrete buoy sits at South Street and Whitehead Street, marking the closest publicly accessible spot to Cuba—just 90 miles away.

Expect crowds and lines, especially midday. Check the live webcam beforehand or visit early morning for shorter waits. The colorful red, yellow, and black striped buoy has been a photo magnet since 1983, making it one of Key West’s most photographed landmarks. The marker also celebrates Key West’s unique identity as the Conch Republic, commemorating the island’s playful 1982 secession.

Currently, you’ll find a full-scale replica at Duval Pocket Park (1400 Duval Street) during reconstruction—the original returns in late 2026. Either way, you’re getting that must-have shot proving you’ve reached America’s southernmost point.
