Key West Museums: 12 Best Picks (2026 Guide & Pricing)

The Hemingway Home and the Key West Lighthouse sit across the street from each other. The 1891 Custom House operates as the flagship of the Key West Art and Historical Society. The Florida Keys Eco-Discovery Center is free and includes a living coral reef tank.

Best for: Treasure hunting history, Spanish colonial maritime archaeology.

The headline museum for treasure-history fans. The Mel Fisher Maritime Museum displays gold bars, emerald rings, silver coins, and salvaged artifacts from the 1622 Spanish galleon Nuestra Señora de Atocha — a treasure ship that sank in a hurricane off the lower Florida Keys carrying gold, silver, and gemstones bound for Spain. Mel Fisher and his diving team searched for the wreck for 16 years before finally locating it in 1985. The museum tells the full story with documentary film footage, recovered artifacts, and ongoing conservation work.

The flagship Key West Art and Historical Society property. The 1891 Richardson Romanesque building is dramatic on its own — built as a US Customs House and Post Office during Key West’s late-19th-century wealth peak. The interior houses rotating exhibits on Key West naval history, the wrecking industry, and Cuban-American heritage, plus a permanent collection of Mario Sanchez folk paintings (the most-collected Key West artist).

The 88-step climb to the top platform delivers a panoramic view of Old Town including the Hemingway House garden across the street. The Keeper’s Quarters museum at the base displays lighthouse-keeper history and Civil War-era Key West life. The KWAHS combo pass covers this plus Custom House plus East Martello at a discount.

The 1851 Spanish Colonial limestone home where Ernest Hemingway lived from 1931 to 1939 — his most prolific literary period. The 30-minute guided tour covers Hemingway’s life in Key West, his second-floor writing studio (with original Royal typewriter), the saltwater pool, and the famous penny embedded in the concrete. About 60 polydactyl (six-toed) cats roam the property as descendants of Hemingway’s original cat Snow White. Plan 60-90 minutes including self-guided exploration after the tour.

Truman vacationed at this 1890 white-clapboard house for 175 days during his presidency (1946-1952), conducting official business including the 1948 Key West Accord that reorganized the US military. The 45-minute guided tour covers Truman’s Key West routine, the Truman Doctrine, and Cold War-era decisions made on these grounds. The house has been visited by every Cold War-era president plus Eisenhower, Kennedy, Carter, and Clinton in retirement.

Key West Shipwreck Treasure Museum

Address: 1 Whitehead Street at Mallory Square.
Hours: Daily 9:40 AM-5 PM.
Tickets: Adults $17, kids 4-12 $9.
Best for: Family-friendly interactive history, kids ages 5-12.

Costumed actors play 19th-century wreckers walking visitors through Key West’s role as the wealthiest city per capita in 1850s America (a fortune built on salvaging shipwrecks).

Tickets: Adults $17, seniors $13, youth $9 ($1.50 online discount).
Best for: Civil War-era fort, the haunted Robert the Doll, quirky history.

A Civil War-era brick fort on the south side of Key West. Houses Robert the Doll — the famously haunted ~3-foot child’s doll behind glass since 1994. Visitors must ask Robert’s permission before photographing (it’s a tradition; many believe ignoring it brings bad luck).

Hours: Daily 9:30 AM-4:30 PM.

San Carlos Institute (Free)

Address: 516 Duval Street.
Hours: Wed-Sun 11 AM-5 PM (varies — call ahead).

Best for: Cuban exile heritage, José Martí history.

Founded in 1871 by Cuban exiles fleeing the Ten Years’ War. José Martí spoke here in 1892 to unite the Cuban exile community in support of the independence movement. Considered “La Casa Cuba” — the cultural center of Cuban exile life outside Cuba.
