Fodor's Expert Review Uncle Charlie's Blue Hole

Mystical and mesmerizing, blue holes pock Andros's marine landscape in greater concentration than anywhere else on Earth—an estimated 160-plus—and provide entry into the islands' network of coral-rock caves. Offshore, some holes drop off to 200 feet or more. Inland blue holes reach depths of 120 feet, layered with fresh, brackish, and salt water. Uncle Charlie's Blue Hole is one of Andros’s most popular with a 40-feet diameter, lined with picnic benches and a ladder.
