Key West does not host a European-style Christmas market, but the island still leans hard into a tropical version of the season every December. Expect palm trees strung with lights, a decorated Norfolk pine instead of a fir, and a laid-back mix of boat parades, waterfront festivities, and Duval Street cheer rather than wooden market stalls.
Every early December, the Historic Seaport at Key West Bight fills with locals and visitors for the island's answer to a Christmas market crowd: a harbor lined with food and drink vendors watching decorated boats cruise past strung with lights, tinsel, and inflatable Santas lashed to the rigging. It is a distinctly Key West mash-up of nautical tradition and holiday kitsch, with sailboats, shrimp boats, and charter catamarans all competing for the best-lit-vessel title. Arrive early to grab a spot along the Bight boardwalk or a table at one of the seaport bars, since the route fills in fast. Expect live music, seasonal cocktails, and a genuinely festive, unpretentious atmosphere. Free to watch from the public waterfront, though restaurants and bars along the route get busy and may add a cover or minimum.
Key West's largest public park becomes the closest thing the island has to a holiday market during December, with a lit community Christmas tree, seasonal food trucks, and periodic weekend events pulling in families from all over the Keys. The open lawns and amphitheater host live music and craft or food vendors on select evenings throughout the month, giving visitors a casual, outdoor gathering spot rather than a formal market. Check the park's event calendar before visiting, since vendor nights and concerts rotate rather than running daily. The waterfront setting means sunset views over the harbor while string lights come on, and there is plenty of open space for kids to run around. Free entry to the park itself; individual food and drink vendors charge separately.
Each December the Ernest Hemingway Home and Museum decorates its towering Norfolk Island pine into one of the island's most photographed Christmas trees, wrapped in lights beside the writer's 1851 Spanish Colonial house. Visitors touring the museum's famous six-toed cats and Hemingway's writing studio get a bonus dose of holiday atmosphere in the tropical garden setting, a striking contrast to typical snowy Christmas-tree scenes. Regular museum admission applies and includes the guided house tour along with the seasonal decor, so it works well as a combined sightseeing and holiday-photo stop. Go in late afternoon for softer light on the tree and garden. The tree typically stays lit throughout December into early January, well past most mainland displays have come down.
Duval Street's shops, guesthouses, and bars lean into palm-tree Christmas lights, wreaths on gingerbread-trim porches, and seasonal cocktail menus throughout December, turning an evening stroll into an easy substitute for a market crawl. Rather than stalls selling mulled wine, expect open-air bars serving rum-spiked eggnog and seasonal drink specials, plus shop windows dressed up for the season. Walk the street after sunset when the lights and string bulbs on balconies and storefronts really stand out. It pairs naturally with dinner reservations along the strip or a stop at Mallory Square, a few blocks away, for the nightly sunset celebration with local performers and craft vendors. No cost to walk and browse; individual bars and shops set their own prices.
