My wife and I visited the Alabaster Caverns before attending the Selman Bat watch program. It is a nice place to visit, and definitely a nice place to cool down on a hot Oklahoma Summer day. It takes a little less than an hour to go through the cave on a guided tour, which I think they do on the hour. You can make a reservation by phone, which is advisable just to make sure you get the tour when you want to take it, and not have to wait for the next one. Other than the cave tour, there didn't seem to be much else to do in the area besides a small gift shop/visitor center. My only complaint is that you don't get much time to enjoy the cave because they keep you going at a fast pace I guess for the next tour. You're pretty much waking non-stop with little time to check up the cave features. Staff were nice, knowledgeable and friendly. I'll definitely go again if I'm in the area.
