Adults and kids alike are having a blast while they beat the summer heat at the world's largest inflatable slip n' slide festival.

Slide The Slopes has set up more than 1.5 miles of water slides on over 20 courses at Beaver Creek Mountain Resort in Pennsylvania.

Not only is Slide The Slopes the longest and biggest inflatable slip n' slide festival in the world, it is also the only waterside event on ski slopes.

The course, which travels across the country, opened Friday on one of the Lehigh Valley's largest mountains and runs through Labor Day.
