Our 10 Favorite Spots for a Summer Splash
Quarry Park and Nature Preserve, Waite Park, Minnesota
Even though it's sanctioned as a county park, this St. Cloud-area preserve delivers thrills equal to the best secret swimming holes. Daredevils climb onto designated spots on rock walls and plunge into a cold, spring-fed pool that's as deep as 112 feet. Swimmers bob across the surface on rafts and inner tubes and do laps between points where the walls aren't as steep. A floating dock (left) makes getting out of the water easy and provides a platform for less-challenging cannonballs.
