The only commercial cave in North Carolina, 30 minutes north of Marion on US 221 in the Linville area. Guided tours of about 30 minutes run through several chambers with the usual stalactites and stalagmites, a small underground stream, and a colony of blind brook trout.
Tours run year round; the cave stays at 52°F regardless of season. A short, easy outing that pairs well with a drive up the Blue Ridge Parkway.
