Alabama: Cathedral Caverns State Park
Cathedral Caverns State Park is named this way for its enormous cathedral-like cave and is located in the northeastern part of the state. It welcomes its guests daily on tours of the cave, where you’ll be able to get a glance at one of the planet’s most enormous stalagmites.
Alaska: Denali State Park
Not to be confused with the National Park, Denali spans more than 300,00 acres. That’s roughly half the size of the entire state of Rhode Island!
It’s almost completely made up of pure and harsh wilderness, except for a couple of beautiful trailheads, two recreational areas, and three campgrounds.
While visiting, you can expect to see a lot of wildlife, including elk, deer, moose, marmots, and even some brown and black bears. This park is a utopia for hikers, but you can also just take a drive through it or a guided kayaking trip.
Arizona: Slide Rock State Park
Arizona has no shortage of spectacular vistas, but Slide Rock’s smooth red rocks and sandstone bluffs in Oak Creek Canyon are fantastic for trekking and fishing in the park’s designated stream.
A can’t-miss in the area is the 80-foot-long Slide Rock Waterslide, where you can slide down the refreshingly nippy waters. The walk to the slide is short and straightforward, but the park has longer trails for hiking enthusiasts.
