Bats in Geironydd (Bryn Cenhadon mine)

Had a look around the back of the mine opposite the hole were the Geironydd stream drops into today and noticed at least a dozen lesser-horseshoe bats roosting in the back of the mine. It’s unlikely groups would disturb them as they’re in the back of the mine off the normal beaten track, but it’d be worth avoiding scrambling into the back of the little mine over winter.
