Crystal Grottoes Caverns have been a top natural attraction in the Maryland region for a century, originally discovered in 1920 following limestone quarrying in the Boonsboro region by the State Roads Commission that led to the exposure of a cavern entrance.
Since 1922, the caverns have been operated as a public attraction, overseen today by third-generation owner Jerry Downs.
Visitors can explore the caverns' gorgeous underground rooms and areas as part of guided tours throughout the year, led by experienced, informative tour guides.
Cavern rooms showcase more formations per square foot than any known cave, showcased in areas like the caverns' Fairyland and Blanket Rooms.
