Natural Wonder in Ohio

January 21, 2021

What’s the most famous natural wonder in Ohio?

Ohio is full of jaw-dropping place, and Serpent Mound ranks at the top of the list. Located in Ohio’s rural Adams County, Serpent Mound is the largest (and most strangely shaped) effigy mound in both North America — and the world. The 1,348 ft. long uniquely shaped mound depicts a snake, with an oval shape at its head. The original purpose of Serpent Mound remains a mystery, but one thing’s certain: this Ohio natural wonder is a must-visit.

Does Ohio have any underground caverns?

Are you ready to experience beauty that’s downright otherworldly? Ohio Caverns — also known as “America’s Most Colorful Caverns” — can be found in West Liberty. The caverns were formed thousands of years ago when an underground river cut through ancient limestone and created vast rooms and passageways. These passageways are now filled with crystal stalactites, stalagmites and many other formations. Within the Ohio Caverns is one of the world’s largest and most perfectly formed stalactites: Crystal King, which is nearly five feet long and weighs an estimated 400 pounds, and is estimated to be more than 200,000-years-old.

What are some other scenic places to visit in Ohio?

For the ultimate scenic experience in Ohio, you can’t beat Hocking Hills. Within the Hocking Hills State Park near Laurelville, you’ll find a .5 mile trail to the beloved Rock House, an aboveground cave with a 25 ft. high ceiling and massive window-like openings that hikers are free to explore — and it will seriously make you feel like Indiana Jones. Hocking Hills also has waterfalls galore, absolutely gorgeous hiking trails, and so much more. Read more about all Hocking Hills has to offer here.
