Water slides are like active volcanoes—both melt away T-shirts, propel fluids down supersteep slopes, and have a lot of screaming women thrown down them. Leisurely lounge or ride the tidal-waved slides with today's Groupon: for $20, you get four all-day passes to Jim Lupient Water Park (up to a $24 value) and Grand Rounds Miniature Golf Course (a $16 value), located adjacent to each other in northeast Minneapolis (up to a $40 total value). Usage of both parks is unlimited.
Owned and operated by the Minneapolis Park and Recreation Board, the water park incites a rush of aquatic adrenaline to foursomes of all ages. Take your bravest limbs for a ride down two snaking slides before testing your GPS's smarts during a speedy exploration of the twisty tube chute, open to riders at least 42 inches tall. The park is designed to look like a quarry, featuring stone accents, pseudo equipment, and foam logs that long to someday be foam houses. Competitive pruney-skinners can challenge strangers to water basketball matches or soak up the dry sun during unlimited 18-hole rounds of mini golf.
