The Great Salt Lake is not the best spot in America for a dip, but its beaches have an ethereal appeal that makes them uniquely strange places to lay out the towel. Antelope Island State Park boasts many of the area's most memorable stands as well as a herd of bison, a bunch of antelopes, and the odd Bighorn Sheep. There's a restaurant and a campground on the island if you want to stay overnight, but it's a better bet to make it a day trip from Salt Lake City, which is just 25 miles north but feels eons away.
