No known access issues with the mines within the gorge. Access to the Klondike level/workings have been gated for some time now.
Please do not enter the first mine on the right (as you’re heading up the gorge) as it releases a significant amount of ochre into the stream
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.
