Dad's Notes:  Rated as one of the top 10 caves in the world, partly because the cave is still 'living'. This means the formations continue to grow, and cave eco-system continues. Reservations an absolute must - at least 2 weeks in advance, more for busy times. Tour is aprox 75min. 68’ F (100% humidity).
     Recently discovered (1974, publicly announced 1988). The only ‘Living’ Cave in the US - the State has put a lot of effort in preserving the cave environment - You will apreciate the work that has gone into keeping the cave ‘alive’. However the work costs money - meaning - yep, this attraction is a bit pricey!
     Discovery center, gift shop, picnic site, Also hiking trails and campground (62 sites) complete with showers and flush toilets. ??Bike trails??
