In place of what once was a sand mine, Crystal City Underground has transformed more than 6 million square feet—approximately 200 acres—of sub-surface space into a climate-controlled entertainment facility. With 30- to 40-foot ceilings, thick pillars carved out of rock, and a lake, it presents visitors with a multifaceted underground experience, one that already includes sand volleyball, disc golf, and weekend barge rides. Future plans for Crystal City have it adding more recreational amenities en route to becoming a subterranean cultural and convention center.
Meramec Valley Campground & RV Park brings people closer to nature via hikes along scenic trails and float trips down the glistening Meramec River. Groups can also cool off in an Olympic-size swimming pool, play mini golf, or visit area attractions such as Onondaga Cave or Six Flags amusement park. Amenities including laundry stations and a lodge with WiFi and satellite TV keep visitors comfortable.
