If you’re looking for a new family adventure this summer, why not head underground? The Midwest is home to a number of intricate cave networks, several of them right here in Ohio, where kids and adults can get up close and personal with the wonders of the underground world, from rock formations to waterfalls, blind cave fish to Ice Age bones.
The best part? These caves stay a cool 54 degrees year-round on average, making them the perfect place to cool off when the temperatures soar. Below are just a few of our favorites.
Ohio Caverns
Location: 2210 East State Route 245, West Liberty, OH
Known as “America’s Most Colorful Caverns,” here you’ll find stunning rock formations in shades of blue, orange, white, red and black. The caverns are the largest in the state, with over two miles of passageways running in depth from 30 feet to 103 feet. Be sure to see the “Crystal King” while you’re there: a huge, perfectly formed white stalactite estimated to be over 200,000 years old. Visit ohiocaverns.com for more details.
