Top 10 Things to Do in Key West

1. Walk through Historic Old Town

Old Town is the best place to understand Key West beyond its waterfront bars and excursion boats. Walk or bike the side streets around Whitehead, Caroline, Fleming, and neighboring blocks to see wooden cottages, larger historic homes, tropical gardens, churches, museums, and the architecture shaped by Bahamian and maritime influences. Duval Street is part of the experience, but the quieter streets reveal more of the island's character. Start in the morning before heat and crowds build, then use museums or shaded stops during the middle of the day.

2. See sunset at Mallory Square

Mallory Square is Key West's traditional sunset gathering place, where performers, vendors, visitors, boats, and the waterfront come together at the western edge of Old Town. Arrive before sunset so the experience is more than a last-minute photograph, then continue on foot into nearby streets or the Historic Seaport. Sunset conditions vary with clouds and weather, so treat the gathering itself as the attraction rather than requiring a perfect horizon view.

3. Explore the Historic Seaport

The Historic Seaport is both a visitor district and a working departure point for boats. Walk the harbor to see charter vessels, schooners, fishing boats, restaurants, and waterfront activity, then use it as the starting point for a sailing, snorkeling, fishing, or eco-tour. This is a better way to understand Key West's maritime identity than treating individual boat brands or operators as attractions. Morning departures suit active water trips, while late afternoon and evening work well for harbor walks and sunset cruises.

4. Visit Fort Zachary Taylor Historic State Park

Fort Zachary Taylor Historic State Park combines a beach with a nineteenth-century coastal fort at the southwest edge of Key West. It is a strong half-day choice when you want swimming or snorkeling without giving up historical context. The shoreline is different from the broad sandy beaches many travelers expect elsewhere in Florida, so water shoes can be useful. Check state-park conditions, hours, and any water advisories before visiting, and allow time to explore the fort rather than using the site only as a beach stop.

5. Visit the Hemingway Home and literary Key West

Ernest Hemingway lived in Key West during the 1930s, and his former Whitehead Street home provides a tangible link to the island's long literary reputation. The house works best as part of a broader Old Town walk rather than as an isolated celebrity stop. Nearby streets also connect to other writers, artists, and architectural history that helped turn Key West into a distinctive cultural destination. Check current tour arrangements and admission details before visiting.

6. Visit the Harry S. Truman Little White House

The Truman Little White House adds an important twentieth-century political chapter to Key West. President Harry S. Truman used the former naval officers' residence repeatedly during his presidency, and the museum interprets those stays within the larger history of the naval station and island. It fits naturally with a walk through the Truman Annex and western Old Town and provides an indoor cultural stop during the hottest part of the day.

7. Get on the water

Key West makes the most sense when at least part of the trip happens off land. Snorkeling trips, sailing, kayaking, fishing charters, wildlife-focused eco-tours, and sandbar outings all reveal the shallow marine environment surrounding the lower Florida Keys. Choose the experience by interest and conditions rather than by boat model or operator name. Wind, visibility, tides, and thunderstorms can affect the day, so keep some flexibility and follow the captain's weather guidance.

8. Plan a Dry Tortugas National Park day trip

Dry Tortugas National Park is a remote federal park about 70 miles west of Key West with no road access. Ferry and seaplane visitors travel from Key West to Garden Key, home to Fort Jefferson, swimming and snorkeling areas, and the park's main visitor facilities. Transportation is limited and often requires advance reservations, so this should be planned as a dedicated excursion rather than added casually to another day. Bring what the operator and National Park Service recommend, review current conditions, and remember that the Dry Tortugas are a separate national park, not part of the City of Key West.
