The original quarry was abandoned over 50 years ago, but was since filled with spring-fed water and had a variety of attractions added to the grounds.

Dive into the water from an elevated diving board, or jump off the surrounding rocks into 30-foot-deep water.

Under water, they've added an "underground waterpark", complete with with planes, sunken ships, old cars, and school buses you can swim around or scuba dive to.
