Water parks pay homage to the way water naturally covers solid earth and the way mushrooms left to grow uninhibited naturally become sprinklers. Get outdoors with today’s Groupon: for $10, you get day passes for two people to CoCo Key Water Park (a $19.90 value).

With more than 54,000 square feet of pools, tube slides, and mounted water cannons, CoCo Key Water Park entertains visitors of all ages with a varied assortment of brightly colored aquatic attractions. Under the vigilant watch of a large lifeguard staff, water frolickers slip safely over the straightaways and drops of rides such as the boomerang slide, which sends inner-tube wranglers swishing up a steep wall before sliding down backwards, passing through a waterfall, and dropping into the pool from which they were originally thrown. Oversize tunnel slides shoot riders through enclosed turns and swift drops that lead to a splash finish and a high-five from a team of Olympic lugers waiting in the pool below.

Younger visitors may ascend the watery fortress of Parrot’s Perch, replete with mounted water canons, pathways and platforms, and a tipping bucket that fills with 400 gallons before drenching anyone standing below. When hunger pangs strike, patrons may stop by Tradewinds for a snack before resuming their impersonations of the precipitation cycle.
