Mel Fisher Maritime Museum
Address: 200 Greene Street.
Hours: Daily from 10 AM, last admission 4 PM.
Tickets: Adults $17.50, children $8.50.
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.
Plan 90 minutes for the full visit. The gift shop sells genuine Atocha-recovered coins (price varies; expect hundreds to thousands of dollars).
Custom House Museum (Key West Art and Historical Society)
Address: 281 Front Street at Mallory Square.
Hours: Daily 10 AM-5 PM (last admission 4:30 PM).
Tickets: Included in the KWAHS Museum Culture Pass; check single-museum admission on kwahs.org.
Best for: Key West cultural and historical context, art exhibits.
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).
Key West Lighthouse & Keeper’s Quarters Museum
Address: 938 Whitehead Street (across from Hemingway House).
Hours: Daily 10 AM-5 PM (last admission 4:30 PM).
Tickets: Adults $17, youth 7-18 $9, under 7 free.
Best for: Old Town views, lighthouse history, combining with Hemingway House visit.
Built in 1825, rebuilt in 1848 after a hurricane destroyed the original. Decommissioned 1969. 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.
Hemingway Home & Museum
Address: 907 Whitehead Street.
Hours: Daily 9 AM-5 PM, 365 days/year.
Tickets: Adults $19, kids 6-12 $7, under 6 free.
Best for: Literary history, the polydactyl cats.
The museum dates this Spanish Colonial limestone home to 1851. Ernest Hemingway lived here from 1931 to 1939 and wrote some of his best-known works during those years. Admission includes a 20-30 minute guided tour, and the visit takes in his second-floor writing studio, the swimming pool (converted to fresh water in the 1940s) and the famous penny embedded beside it. Nearly 60 cats roam the property; about half are polydactyl (six-toed), and some descend from Hemingway’s original cat Snow White. Plan 60-90 minutes including self-guided exploration after the tour.
Truman Little White House
Address: 111 Front Street.
Hours: Daily 9:30 AM-5 PM; check in at the Truman Annex kiosk for the next guided tour.
Tickets: Adults $24.67 (less online), kids 4-12 $11, under 4 free.
Best for: Presidential history, Cold War-era policy decisions.
Florida’s only Presidential museum. Harry S. 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. Allow about an hour for the guided tour, which 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 AM-5:30 PM (final entry 5 PM).
Tickets: Adults $18.26 ($18 online), kids 4-12 $9.66 ($9 online).
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). The 65-foot lookout tower at the end provides a Mallory Square overhead view. Combo tickets with the Aquarium next door reduce per-attraction cost.
Fort East Martello Museum (Robert the Doll)
Address: 3501 South Roosevelt Boulevard.
Hours: Daily 10 AM-5 PM (last admission 4:30 PM).
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 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). The fort also displays Stanley Papio’s metal sculpture art and Civil War-era Key West history. Part of the KWAHS combo pass.
Audubon House & Tropical Gardens
Address: 205 Whitehead Street.
Hours: Museum daily 9:30 AM-4:15 PM; gallery and gift shop 9:30 AM-5 PM.
Tickets: Check current admission on audubonhouse.org.
Best for: Tropical garden walks, John James Audubon historical context.
A historic maritime pilot’s home set in one-acre tropical gardens of orchids, bromeliads, palms and crotons. John James Audubon visited Key West in 1832, and the museum honors that visit.
USCG Cutter Ingham Maritime Museum
Address: Truman Waterfront pier.
Hours: Tue-Sat 10 AM-4 PM.
Tickets: Adults (13+) $20.
Best for: Maritime/military history, walking the deck of an actual decommissioned cutter.
The USCG Cutter Ingham — a National Historic Landmark — sits permanently at Truman Waterfront. The cutter served in WWII (Atlantic convoys, U-boat hunting), Korean War, Vietnam War, and the Mariel boatlift. Self-guided tour through the engine room, mess deck, captain’s quarters, and pilot house.
San Carlos Institute (Free)
Address: 516 Duval Street.
Hours: Check the visit page on institutosancarlos.org or call ahead.
Tickets: Free admission.
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. The ornate Duval Street building (the institute was rebuilt after fire badly damaged its original home) features Spanish-Cuban architecture and a small museum of Cuban-American heritage. Often combined with a stop at El Siboney or El Meson de Pepe for a Cuban-heritage afternoon.
Key West Aquarium
Address: 1 Whitehead Street at Mallory Square.
Hours: Daily 9 AM-6 PM.
Tickets: Adults $20.99 ($15.99 online), kids 4-12 $11.99 ($7.99 online), under 4 free.
Best for: Families, marine life encounters.
Although technically an aquarium rather than a museum, the Key West Aquarium (open since 1935) belongs in any Key West museums conversation. Touch tanks, daily shark and stingray feedings, sea turtle conservation tour. Plan 90 minutes.
KWAHS Combo Pass
The Key West Art and Historical Society offers combination passes covering three of their properties at a discount:
KWAHS Museum Culture Pass: $45 general admission covers the Custom House, Key West Lighthouse, Fort East Martello and the Tennessee Williams Museum (closed during its move), and the tickets never expire.
