Swim Alligator Light


Swim Alligator Lighthouse registration opens each year on February 1 and closes when the swim reaches 400 participants. Swimmers can register as solo, two-person or four-person relays.


The 9-mile swim to Alligator Lighthouse is a challenge. It’s not for the faint of heart. This is tropical open water swimming. If you’ve never done anything like this before, you will encounter stunning (for some stinging) and beautiful marine life. Year after year, people return to conquer Alligator Light!


Swim Alligator Light is more than an open water swim. It’s a multi-day experience in the Florida Keys. If you are traveling to Islamorada, we invite you to make plans to stay for a few days with friends and family. We call this paradise for a reason.
