Marathon vs Key West vs Key Largo: What's the Difference?
Marathon is the most family-friendly area in the Florida Keys. It has the best beaches, larger resorts, and a slower pace that makes traveling with kids easier. Resorts like Hawks Cay Resort and Isla Bella Beach Resort are designed for families, with pools, activities, and space.
Key West is more active and compact. It has attractions, restaurants, and things to do, but fewer beaches and less space. It works better for families with older kids who can enjoy the walkability and dining scene.
Key Largo is closest to Miami and best for short trips. It is more focused on diving and snorkeling than traditional family resort experiences. John Pennekamp Coral Reef State Park is the main family draw.
Best for Families Overall: Marathon Wins
Marathon offers the best combination of beaches, space, and family-friendly resorts in the Florida Keys. Hawks Cay Resort has dolphin encounters, a saltwater lagoon, multiple pools, and a full-service marina. Isla Bella offers private beach access and modern amenities.
Best for Beaches: Marathon Wins
Sombrero Beach is the best public beach in the Florida Keys — large, sandy, and uncrowded. Marathon has the most accessible sandy shoreline in the Keys, making it the clear winner for families who want beach time.
Key West has smaller beaches like Smathers Beach, but beaches are not the primary draw of the island.
Best for Family Resorts: Marathon Wins
Resorts like Hawks Cay and Isla Bella are built for families, with pools, activities, beach access, and space that Key West and Key Largo cannot match.
Best for Walkability: Key West Wins
Key West is the only walkable destination in the Florida Keys, making it easier for families with older kids to explore restaurants, shops, and attractions without a car. Duval Street, Mallory Square, and the Key West Aquarium are all within walking distance.
Best for Short Trips: Key Largo Wins
Key Largo is the closest Key to Miami — about 1 hour by car — making it ideal for quick family getaways focused on snorkeling or nature. John Pennekamp Coral Reef State Park offers glass-bottom boat tours and snorkel trips that work well for kids.
