Consistant 56 degrees all year round
Nice and earm in the winter cool in the summer. But a jacket or sweater thats light would be good. You will be taking it off. So light is best since you will be carrying it . Super cool cave.
In the 60's bring a small sweater or hoodie you will get warm with all the walking. I always end up taking my sweater off and putting in my bag
56° on the hottest day of the summer and on the coldest winter night its 56°..
Justin is correct. It is 56 degrees year round with 99% humidity. Layering is always recommended.
