The No Shoes Reef 4 lies in 70 feet of water off of Delray Beach. This 32-acre underwater park was installed in 2021 by No Shoes Reef, a grassroots organization led by country music superstar Kenny Chesney. The organization and other marine groups donated 13 reef balls to the ocean floor. The aim of No Shoes Reefs is to protect and rehabilitate troubled coral reefs and marine ecosystems.
