Sleeping Bear Dunes National Seashore, Northwestern Lower Michigan Why you've got to go: You'll never see sand dunes like these anywhere else! Some are nearly 500 feet high, with jaw-dropping views of Lake Michigan and the Manitou Islands from the top.
We were lying in the sand at Sun Bay beach in Vieques. We'd been told to watch out for horses, but nothing could prepare me for this. What a majestic experience to see wild horses free on the sands of Sun Bay beach.
