Annual Swim for Alligator Light

Annual Swim for Alligator Light The Swim for Alligator Lighthouse is an annual 8 mile open water swim that takes place in Islamorada, the Florida Keys. It took him five hours and 11 minutes.

Swimmers can race solo, or as part of a relay up to four swimmers. The Swim for Alligator Lighthouse is an annual 8- mile open water swim that takes place in Islamorada, the Florida Keys. At 52 years old, Fighting Manatee Larry Herlth decided to swim to Alligator Reef Lighthouse and back. He was escorted by several boats and paddle boarders. Moments after finishing this swim, Larry asked, "I wonder if anyone would join me in this challenging swim through the beautiful blue Atlantic Ocean of the Florida Keys?"

Clearly, the answer was a resounding yes. Known locally as “Lighthouse Larry” for his detailed, scale metal reproductions of Keys lighthouses, Herlth is passionate about the need to preserve the large beacons originally fabricated in the 1800s to warn ships away from the Florida Keys reef tract. "One of the best open water swims in the world," combined with the fabulous Islamorada and Florida Keys hospitality and charm, make this a swim you won't want to miss! Register today, the race is limited to 500 swimmers.

Safety is our highest priority at the Annual Swim for Alligator Light, and every swimmer and kayaker plays an important role in a successful race.

This video highlights key swimmer and safety kayaker responsibilities, communication, and on-water awareness. Please note that some of the AI stock footage is for demonstration purposes only and does not exactly reflect our race equipment or operational procedures. For example, our race utilizes sit-on-top safety kayaks, even though some scenes in the video show sit-in kayaks.

Take a few minutes to watch the video, review the procedures, and arrive prepared. A safe race is a successful race, and that starts with every member of our race community.
All registered participants and volunteer kayakers should follow the official race briefing, safety meeting, and written race instructions as the authoritative source for event protocols:
