Me and John, My first of what I hope many caving trips with John, we went to cavern 52 which he had no issue with so I then took him on the round trip in there for more of a challenge, up to the gour pools then down, through the dried up sump and then back up the pitches (free climbing). John free climbed these with ease. We exited and I took him to Gour hall at the back of Mystral, a more boring trip but plenty to see.
Times are of both caves.
