The caves were closed by Covid, but I enjoyed the hike and wildlife. There’s a private site nearby that apparently is still conducting “ice cave” tours. I’m happy to leave the bats alone underground and not risk introducing fungus or disease. I suppose it’s ironic to have the cave closed here when Covid likely originated from a bat cave in China. But the larger problem is that climate change is spreading more diseases globally, affecting both us and other species, so we need to be more responsible.
