Best Things to Do in Key West with Kids

Things to do in Key West with Kids

A trip to Key West with kids is sure to be filled with fun, learning, and loads of adventure.

Here are some of our favorite things to do in Key West with kids:

Conch Train Tour in Key West

1. Conch Train Tour

One of our favorite ways to get an overview of Key West is with a trolly tour. You will find that there are several to choose from on the island, but our preferred Trolly Tour is the Conch Train Tour.

Powered by GetYourGuide

You will get to see all the popular sites and it gives you an excellent overview of the area without having to walk everywhere.

What also makes it a popular thing to do with kids in Key West is the fact that it is hopping on and off, so you can get from one part of the island to the other relatively easily.

2. Dry Tortugas National Park (2-hour boat ride from Key West)

Dry Tortugas is one of Key West’s most significant landmarks and home for Fort Jefferson and is surrounded by natural wildlife and some of the best coral reefs in North America.

The Dry Tortugas participates in the National Park’s Junior Ranger Program for kids. This teaches kids about the park’s local wildlife, history, and natural features.

Make sure to pick up the Junior Ranger Handbook at the visitor center, or download it & print it out before your trip. If kids complete all the activities in the handbook, they can receive a Junior Ranger badge at the visitor center.

One fun activity for kids at Fort Jefferson is to look for the carvings from master bricklayer J.N.O. Nolan. During his time working on Fort Jefferson, Nolan etched his name in several places at the fort.

Snorkeling at Tortuga

If you want to snorkel in Key West with kids, this is a perfect place.

The crystal clear water is between 5-15 feet and allows you to see beautiful fish, sea turtles, and coral.

The 100-square-mile park is accessible only by boat (or seaplane) so you will have to take a ferry to get there.

The Ferry will supply you with complimentary snorkel gear.
