A bit on the pricey side, but very interesting nonetheless, and worth the while, I think. Probably more fascinating than all of the caverns the guides take you into are all of the caverns they DON'T take you into, but describe instead. If I'm not mistaken, Wookey Hole is a "work in progress" in that it is still being explored. The adjoining museum is good in helping to understand the caves' place in history.
