I'm afraid of heights and am not a very good swimmer, so this might just be my worst nightmare come true. It's Missouri's largest underground lake that plunges down 100 feet into the earth and is 400 feet long.

Have you ever heard of this hard to access Missouri underground lake? It's the Devil's Well and Wikipedia tells the story of how it was discovered and how big it is. History says it was unearthed (literally) in 1954 by two brothers Bill and Bob Wallace. It's an underground cavern near Akers, Missouri.

Cassidy's Adventures on YouTube visited it just days ago. The Devil's Well part of their video starts at around the 20 minute mark.

This is quite a large underground water place. 400 feet long and 100 feet wide and 100 feet down. That's some steep Missouri water math right there.

The National Park Service says Devil's Well in Missouri is an opportunity to look at "the Earth's plumbing". They also warn that it's not super-easy to visit with a 4.6 mile hiking trail that leads to it. The road leading up to the trailhead is a little rough, too, and they don't recommend trailers or motorhomes attempt it. The good news is there's no cost to view this well and it's open year-round during daylight hours.
