My husband, 4 year old daughter, and I visited Cave Without a Name today and greatly enjoyed out visit. We had visited Caverns of Sonora last year and are trying to complete our Texas Cave Trails Passport. The tour is about 1 hour long and takes you through 6 rooms of the cave. You descend about 80ft. under ground, so be prepared to take some stairs. (Think an eight story building!) So, after visiting Caverns of Sonora (which was our first cave to visit as a family), I think we felt we had seen them all... Not true. Sonora is very sparkly, but Cave Without a Name has much larger rooms and formations. It was well worth it's own visit. They are both beautiful in their own ways. The tour tickets and gift shop items were all reasonably priced and our daughter had fun panning for gems after the tour. Be aware that the cave is under improvements and you may see some occasional wiring or PVC pipes. While it may not appear perfectly natural, the cave wouldn't be accessible otherwise, and I certainly can't fault anyone for improvements!
