Beat the summer heat by visiting Crystal Grottoes caverns, where you can check out the rock formations and stay cool underground.
Crystal Grottoes is located in Boonsboro, at the foot of Maryland’s South Mountain Range.
These caverns are unique as they were formed in a syncline—a concave fold or bend in the rock layers. Take a 35-40 minute guided tour, where you can wander along a well-lit, gravel path through the caverns’ seven different chambers to catch a glimpse of many rock formations including stalactites, stalagmites, columns, rimstone pools and more.
Crystal Grottoes Caverns is about an hour and 40 minutes from Annapolis. Tours depart on the hour daily from 11 a.m.–4 p.m.
$20 adults; $10 children 11 and younger (cash only).
