Key West is a subtropical paradise of just seven square miles, packed with exciting and romantic things to do for couples.

More than 100 miles from mainland Florida, Key West is the southernmost region of the continental U.S., infused with the sights and scents of the tropics and at the same time, quirky, creative, and romantic. Little wonder, then, that artists, writers, and musicians have long been drawn to the island city.

Along with diving and snorkeling, discover Key West for yourself by exploring art galleries, strolling Duval Street, unraveling the history of the island, and sharing a slice of scrumptious Key lime pie with your loved one.

Enjoy this selection of 14 romantic things to do in Key West for couples.

Snorkel Over Coral Reefs

Snorkeling in the Florida Keys

The Florida Keys are part of North America’s only living coral reef. Discovering the beauty of the underwater world together is one of the best things for couples to do in Key West.

As one of the best islands for snorkeling, Key West is a delight for divers and snorkelers with its clear waters, thriving reefs, and wrecks in relatively shallow depths.

As your boat heads to a snorkel and dive site, enjoy the wind in your hair as you look out for dolphins cruising the tropical waters. At Rock Key, seven miles southeast of Key West, you could spot moray eels and grouper in the wide crevasses and canyons—and at the same time, see cannonballs and ballast stones from shipwrecks.

Divers and snorkelers at Eastern Dry Rocks Reef, near Rock Key, can view conch, sea turtles, brain coral, angelfish, tarpon, and barracuda.  Sand Key, seven miles southwest of Key West, is known for loggerhead turtles, grouper, barracuda, and dazzling corals.

In the shallow waters of Cottrell Key, a mangrove-filled island nine miles northwest of Key West, you can float above sponges and sea fans, listening to parrotfish munching on the coral.

Stroll Through Key West Tropical Forest & Botanical Garden

Strolling through the Key West Tropical Forest & Botanical Garden is a romantic activity for couples. A walk through the greenery provides a sense of natural Key West and the Caribbean as the land was before development.

Butterfly on a leaf

You meander through a canopy of tropical trees and pass by Champion Trees, specimens that rate among the tallest of their type, including a stalwart locust berry, cinnamon bark, and saffron plum.

The waterfall and the butterfly gardens make for a particularly romantic backdrop for pledging one’s affections.

Swim & Snorkel at Fort Zachary Taylor State Park

Fort Zachary Taylor State Park

Fort Zachary Taylor State Park features Key West’s best beach. Sunning, swimming, and snorkeling at this park is a dreamy way for romantics to spend the day.

Tall Australian pine trees sway in the breeze, and snorkelers might spot lobster, snapper, parrotfish, and other tropical beauties near the jetties.

At the Chickee Hut, rent snorkel gear, chaise lounges, and umbrellas. For lunch, the park’s Cayo Hueso Café plates ham and cheese, grilled chicken, burgers and traditional Cuban sandwiches.

Allow time to discover the park’s other side, the historic fort. Despite Florida’s status as a southern state, Union forces controlled the fort during the Civil War.

The U.S. Navy deterred Confederate ships from bringing supplies and weapons to Confederate ports. Be sure to see the fort’s impressive row of cannons.

Pay Homage to Inclusivity

In 2000, Key West adopted “One Human Family” as the city’s official philosophy. At Duval and Petronia streets, four crosswalks striped with the colors of the rainbow flag, a symbol of LGBTQ+ unity, symbolize both Key West’s Gay pride and the city’s welcoming attitude to all.

Initially installed in 2015, the landmarks were repaved in 2020 to make the colors pop even more brightly.

Overlooking the Atlantic Ocean, the Key West AIDS Memorial, completed in 1997, features the names of 1,000 men and women who have lived in, worked in and visited Key West and died of AIDS.

With a long history of inclusion, Key West became popular in the 1970s as a gay-friendly destination as more and more LGBTQ+ people gravitated to the city. It continues to be a safe and welcoming place for couples, regardless of gender or sexual orientation.

Take a Selfie at Southernmost Point

Visit the iconic Southernmost Point, one of the best things to do in Key West

Southernmost Point

A fun thing for couples to do in Key West is to take a selfie at the Southernmost Point Buoy at the end of Whitehead Street. The colorful marker’s Key West iconography says it all.

The sides of a yellow triangle identify your location as  “The Conch Republic” and a conch shell floating in blue serves as the insignia. The signal’s red, black, and yellow bands trumpet “90 miles to Cuba, Southernmost Point Continental U.S.A., Key West, Fl.”

While waiting in line (usually there is one) for the perfect shot, enjoy the dazzling ocean view.

Nearby, try Key West’s local fare by lunching at Ana’s Cuban Café. Residents and visitors rave about the Cuban sandwiches here. Or bite into a tasty lobster roll at the Key West Lobster Shack.

Climb the Key West Lighthouse

Keep thinking of the glorious view as you round the 88 steps to the catwalk of the Key West Lighthouse.

From the uppermost viewing area of the sentinel, which was constructed in1848, Key West appears in all its glory—a ribbon of greenery and white beaches surrounded by the aquamarine Atlantic Ocean and the Gulf of Mexico.

When the keeper of the 1825 light, the first erected on the site, died in 1832, his wife Barbara Mabrity took over, becoming the first woman lighthouse keeper in the U.S.

After a hurricane in 1846 destroyed that lighthouse, the current one opened. In the Keeper’s Quarter’s Museum, you can view historical documents and see how the keeper and family lived.

Pay Your Respects at Higgs Beach

Higgs Beach

Higgs Beach is also noted for its Key West African Refugee Cemetery and memorial marking the graves of 294 African men, women, and children who died in Key West.

In 1860, the U.S. Navy intercepted three ships carrying 1,432 free Africans slated to be sold as slaves in Cuba. Even though the military provided food, clothing, shelter, and medical treatment, 294 of the Africans perished.

Historians believe the Higgs gravesite to be the United States’ only African refugee cemetery. This poignant fact aside, Higgs Beach is a glorious spot for sunbathing, swimming, and further from the shore, snorkeling over colorful reefs.

Paddle a Kayak at Smathers Beach

Swim in Smathers Beach, one of tbe best things to do in Key West for couples

Smathers Beach

Locals say the soft white sand at Smathers Beach, the largest public beach in Key West, is imported from the Bahamas. This in no way diminishes the beauty of the beach, shaded by swaying palms and almost a mile long, the shore sloping gently into the calm, turquoise waters.

Test the strength of your relationship by renting a double kayak and paddling through the shallow waters.

This can be a bonding activity—but if you find your teamwork doesn’t extend to kayaking, you can always jump ship into the warm, clear water.

Share a Key Lime Pie

Key West has proclaimed itself the Conch Republic, and at Louie’s Backyard, a well-known restaurant, you’ll find out why. Sit on the deck with its ocean views, and order conch, pronounced “konk”.

Like many places, Louie’s serves conch in chowder, as a coconut ceviche, or deep-fried as fritter.

The Conch Republic Seafood Company’s specialty is cracked conch, tempura-battered conch lightly fried and served with orange horseradish marmalade.

Cuban sandwich on a plate

Don’t favor seafood? No problem. Cuban fare is a Key West staple. At Sandy’s Café, bite into a Cuban Mix Sandwich of ham, pork, salami, and Swiss cheese.

Visit the Hemingway House

Hemingway House

For some, it’s a shrine, and for others, a curiosity. Either way, visiting Hemingway’s House is essential for literary-minded couples to do when visiting Key West.

The Spanish colonial-style home, a gift in 1931 from a wealthy uncle of Hemingway’s wife, was built in 1851. The couple refurbished the house, living at the residence from 1931 to 1939.

At the estate, Hemingway completed such famous works as Death in the Afternoon, The Green Hills of Africa,  and The Snows of Kilimanjaro. Spanish colonial furnishings, a favorite style of the author, adorn the rooms.

The estate is graced by some 60 cats, descendants of  Snow White, a white, six-toed cat gifted to Hemingway by a ship’s captain. Although all the felines carry the six-toed gene, only half of the kitties actually pad around on six toes.
