Off the northeast coast of Antigua, this spot is known for—you guessed it—abundant exotic bird populations, including red-billed tropicbirds, and the West Indian whistling duck. While burying your toes in the sugary sand, look for other unique wildlife such as the (harmless!) Antiguan racer snake.
Be sure to: Snorkel from the soft sandbar and explore the surrounding coral reef.
How to get there: Travel by private boat, or take a day sail from Antigua on Treasure Island Cruises; treasureislandcruises.ag.
