Hi, which one would be better, more interesting for trip? Colors, formations , lenght of tour. Thanks in advance.
I think that anything in Mammoth will be much more interesting than Diamond cavers, with the exception of the Frozen Niagara tour. Most of the tours are significantly longer, and there's far more history involved. Diamond Caverns probably gets the edge for its formations, though Cleveland Avenue is well decorated with a different type of formation. You might see better colors at Diamond, but Frozen the Niagara tour is going to be fairly similar. Those colors are going to mostly be different shades of brown and tan, with a bit of white, and some tans that are a bit orange.
