Planning a family vacation to Key West? You might be surprised to discover just how much this little tropical island has to offer beyond its famous sunsets and lively Duval Street.
From exploring colorful coral reefs to spotting sea creatures, visiting historic landmarks, and enjoying beautiful beaches, Key West is filled with adventures for children, teenagers, parents, and grandparents alike.
Whether your family loves the ocean, wildlife, history, or simply spending quality time together, here are 10 of the best family activities in Key West to make your vacation unforgettable.
1. Discover the Underwater World With SNUBA Diving
Best for: Families with children ages 8 and older
Imagine your child’s excitement when they discover they can actually breathe underwater, swim among tropical fish, and explore the fascinating marine world of the Florida Keys — without needing scuba certification.
That’s what makes SNUBA diving one of the most unique family activities in Key West.
SNUBA combines some of the best parts of snorkeling and scuba diving. Unlike traditional scuba diving, guests don’t carry heavy air tanks on their backs. Instead, air is supplied through a hose connected to a floating raft at the surface, allowing participants to explore underwater while breathing comfortably.
At SNUBA Key West, operating since 1999, families can enjoy professionally guided underwater adventures designed for beginners and experienced ocean lovers alike.
Why families love SNUBA:
- Children ages 8 and older can participate.
- No scuba certification or previous diving experience is required.
- Non-swimmers may be able to participate after an individual comfort and safety assessment.
- Professional SNUBA guides accompany guests underwater.
- Small guided groups allow for personal attention.
- Participants can explore at comfortable depths, up to 20 feet, as conditions and individual abilities permit.
- Families have opportunities to observe colorful tropical fish, coral formations, and other fascinating marine creatures.
Before entering the water, guests receive an introduction to the equipment, breathing techniques, and underwater safety procedures.
The best part? SNUBA gives parents and children the opportunity to discover an entirely different world together.
Local tip: You don’t have to be an experienced ocean explorer to appreciate the marine life around Key West. Sometimes the most amazing discoveries happen in shallow water, where tiny fish, crabs, lobsters, and other creatures hide in plain sight.
