Enjoy a guided 90-minute, half-mile walk into this beautiful cave. See nine rooms with amazing stalactites, stalagmites, and banded travertine. Be prepared for the 400 steps up and down in the cave and bring a jacket, since the cave is cool at about 40 degrees year round. Open 7 days a week from 10 a.m. to 5:30 p.m. from mid-June to Labor Day depending on the weather. Please visit their website for hours, entry fees and safety information.
