This has been an great addition to the list of summer activities in the Denver area. Pirate's Cove is a very pleasant outdoor water park. It is not nearly as big as Water World, and it does not have the dramatic theme rides that Water World features. However, the adult admission price is just $7.50, and for that price, you get plenty of bells and whistles, including three very long and twisty water slides, and a lazy river ride. You can easily spend a full day here, cool off, and be entertained.
