Did the Plughole adventure in Jenolan caves on the weekend. We did it as part of an organised tour as I’m not sure if you can go caving by yourself in Jenolan caves.
There was 11 of us and the cave started with an abseil down. The caving was quite fun and it was slow going due to the size of the group and also because there were two areas which were a tighter squeeze which some people struggled. I was able to take a few photos and videos, so was very happy about it.
