My favorite undiscovered beach? Simple - Barbuda. Hugging the coast of Antigua, Barbuda is an easy puddle jump away. The beach sand is pink (yes, pink), and the turquoise water crystalline. The short boat ride out to the beaches passes one of the most significant nesting colonies of magnificent frigatebirds in the Caribbean.
In Ohiopyle State Park the Youghiogheny River pulls a 180 and drops over 100 feet in the maneuver. The result is some of the best white water in the east. The brave (or foolhardy) plunge kayaks over the falls.
