What To Do In Key West When It Rains - 11 Best Indoor Activities

What To Do In Key West When It Rains

You’ve planned the perfect Key West family vacation. You bought coral reef-safe sunscreen spray, lotion, and stick. The perfect trip is off to a great start. For the first two days, the sun is shining, and there isn’t a cloud in the sky. Last night you watched a magical sunset with the group at Mallory Square. This morning, the unthinkable happened. The rain clouds rolled in, and the sky opened up with liquid sunshine.

Do not despair. There are plenty of rainy-day activities to enjoy for families, kids, and adults. The rain in Key West rarely lasts all day. Tropical rain showers pass quickly through this island paradise, and by the time you are finished with your first indoor activities of the day, the sky will likely be blue and cloud-free again.

The rainy season is from June through October, with September coming in at the top with an average of 22 days of rain. However, that does not mean it will rain every day. If you have kids in school, the summer months may be the only time you can travel. If that is your story, then plan to add a few rainy-day activities to your trip, just in case.

Many of Key West’s most popular attractions are indoors, and without this change in the weather, you may have missed them. So let’s double down on the perfect vacation and discover what activities in Key West are fun when it rains.


1) Visit The Key West Aquarium On A Rainy Day In The Florida Keys

If you woke up to a rainy day and are searching for rainy-day activities in Key West for families, we suggest you start with the Key West Butterfly and Nature Conservatory first followed by the Key West Aquarium. The Butterfly and Nature Conservatory is on the south side of the island. Plan to spend about an hour here.

At the aquarium, you can tour the Sea Turtle Conservation exhibit, get up close with the sharks, and let the kids hold the critters in the Touch Tank. The Key West Aquarium is next to Mallory Square, where there just might be a cruise ship or two lined up at the dock. You’ll find plenty of places to step inside for lunch and, of course, some Key Lime Pie.

The Key West Aquarium is open from 9 am to 6 pm daily, and you will probably spend about an hour enjoying the exhibits.

3) Key West Indoor Activities For Teens On A Rainy Day

From Mallory Square, it’s only a few steps to an attraction the whole family will enjoy on a rainy day and especially the teens. If you are looking for a cure for grumpy teen boredom, then head to the Mel Fisher Museum.

In 1985 Mel and his crew found the wreck of a 400-year-old Spanish ship called the Atocha. Within the wreck was around $400 million worth of silver bullion, ingots, coins, gold bars, and silverware. Kids, adults, and all history buffs will enjoy the story of how Mel Fisher’s team and family made this vast discovery and the subsequent drama surrounding its recovery.

The Mel Fisher Museum is open daily from 10:00 am to 4:00 pm, and you will want to spend about an hour exploring the exhibits.

4) Take The Key West Conch Tour Train

In 1912 Henry Flagler’s Overseas Railroad opened, connecting the Florida East Coast Railway to Key West. Unfortunately, a category five hurricane, the Labor Day Hurricane of 1935, destroyed the Overseas Railroad. However, the iconic Conch Tour Train still exists today, giving tours to visitors.

Purchase tickets in advance. You’ll board the conch tour train at the Station Depot on the corner of Front Street and Duval. The 75-minute narrated tour runs on a loop that makes three stops before finishing at Mallory Square:

  • Station Depot for shopping and refreshments.

  • Truval Village, where riders can choose to disembark and see the Historic Seaport, the Ernest Hemingway Home, Key West Lighthouse, Southernmost Point, and the Key West Butterfly and Nature Conservatory

  • Sails to Rails Museum at the corner of Caroline and Grinnell Streets, next to the Key West Bight ferry terminal.

If you are visiting Key West as a port stop on a cruise ship, the Conch Train is the perfect activity to see the historic sites. It’s an easy walk from the cruise ship dock to where the train begins and ends.

Key West Sunset Cruise

Ocean, meet our captain! One of the best things about the backcountry waters is how it’s never too crowded. So jump in and enjoy the peacefulness and remoteness as you stand in the "middle of the ocean" with nothing but water around you. Optionally, bring some champagne to enjoy with the sunset as a backdrop. Then, just sit back and relax as you cruise on out into the middle of nowhere, leaving behind any stress or worries.
