The entrance is beautiful, but the cave itself nothing special. Anyway if you go for a walk in the forest, stop by.
Sad history behind it
If you are nearby, it was good for a quick stop. I would have been pretty disappointed if I had driven more than 30 minutes out of my way to see it though.
Asbourne castle is a great place and lovely walks around the grounds
Cool little place to go on a mini adventure when walking in the woods.
