We read about Linville Caverns on Trip Advisor and it sounded pretty good, so Heather, my brother Jim, and I decided to check it out. The caverns were a bit on the small side and had to be the wettest caverns we've ever visited - we were soaked by all the dripping. There wasn't a lot of formations but it was a good place to check out, at least once.

I took these photos on 1 May 2015
