Every visitor to Cayman Brac is welcome to a free guided tour of the island courtesy of Nature Cayman. Thanks to the warm, affable Keino St. Aubyn Daley, every tour is different, and always comes with a surprise. It may be the 25 million-year-old caves and brown booby sightings that fill up the day. Or it could be a morning snorkel and a stop at a Bracker's home for fried fish, fritters, and a few stories. It's choose-your-own-adventure, with a side of Caymankindness.
