One of the most well-known snorkel sites in The Palm Beaches can be found under Blue Heron Bridge on Singer Island. The Blue Heron Bridge connects Signer Island to the mainland. On the small island under the bridge in the Lake Worth Lagoon, there is a 15-acre beach park. Phil Foster Park is a life-guarded beach, fishing area, and playground. With easy access from a sandy beach averaging depth of 6-10 feet. It is a picture-perfect place for shore snorkeling and shallow-water diving with its clear waters and abundant sea life. The Blue Heron Bridge snorkeling trail is about 800 ft long and runs about 200 ft offshore.

The beginning point is located under the bridge at Phil Foster Park. Snorkelers can take off from the swimming area to do the Snorkel Trail. The depth around Blue Heron Bridge goes from four feet at the entry point out to twenty feet near the boat wrecks. The Snorkel Trail ranges from 10 to 15 feet. With translucent water and rich aquatic life. Squid, an octopus, spotted rays, and starfish are regularly seen. The beach park is a wonderful place to dive and became one of the best snorkel places in South Florida.
