Here are six activities that are free or relatively low cost that you can do with kids in Key West, FL. I had heard that that there weren't many things to do for kids in the keys and that there were no beaches. Both of those things are untrue.

1. Walking around Old Town
2. Seeing the sun set at Mallory Square
3. Biking around the island
4. Beaches Smathers, Higgs, Zachary Talyor
5. Parks and Playgrounds
6. Kayaking
