There's something about summertime that makes locals start seeking out activities that get their adrenaline pumping. With that in mind, it's important to keep a bucket list of once-in-a-lifetime and never-been-done-before experiences handy and ready to add to at all times. Missourians are in luck because there's an underground cave near St. Louis that you can kayak in and it's fully worthy of taking the #1 spot on your list.\nCrystal City Underground in Crystal City, Missouri offers kayak and canoeing tours, as well as camping, disc golf, and pole vaulting all beneath the surface.\nCurrently, as of May 2020, the cave is closed due to flooding, however, they are open for special occasions.\nYou can visit their website here to contact the appropriate people to see just when those special occasions are.\nCamping is offered during weekends where an eclipse is taking place, for $50 per night for a family of 2 adults and children. Any additional person is $10 per person.\nKayak and canoe tours are offered year-round when flooding is under control. The owners have hopes to reopen come late fall, and that's definitely something to be excited over.\nView this post on Instagram Spent a nice sunny weekend underground. #PaddleKC #CrystalCity A post shared by Jessica Crumrine (@jesscrumrine) on Jan 28, 2018 at 5:33pm PST\nOnce the water recedes, the disc golf course will reopen for all kinds of disc golf and pole vaulting fun.\nExcercise hits different when it's done underground.\nView this post on Instagram Some photos from cave kayaking. 2nd cave down, many more to go.
