Best State Parks for Summer Swimming
State parks offer some of the best swimming holes in the USA – often free or for just a few dollars entrance fee. From natural waterslides in Arizona to crystal-clear springs in Florida, these parks deliver refreshing summer experiences.
Slide Rock State Park, Arizona
Nature’s own water park. Smooth red sandstone creates a natural 80-foot waterslide in Oak Creek Canyon. The creek-carved chutes and pools draw thousands on hot summer days – arrive early on weekends to secure parking.
Devil’s Den State Park, Arkansas
A spring-fed swimming pool set among Ozark bluffs and caves. The CCC-built pool maintains refreshingly cool temperatures even in the peak of Arkansas summer heat.
