Wonderland Cave

This was a great find, and not as packed as the other caves, where you had to schedule far in advance or not get in. Tour guides were very knowledgeable and made it that next level of fun. Very diverse rock formations.

A nice cave -- we visited in the 1980s. It was hard to pass up any attraction touting a "famous 40-ft. long icicle fence." Though GPS makes us much wiser now, this remote Black Hills show cave became our poster child for misleading, overly optimistic billboards. "Only 2 more miles!"
