The end of the cave was in a big chamber where you had to scramble up a big heap of boulders to a high region where we planned to camp. We would spend one day getting to camp, one day pushing and surveying, and the third day coming out. It took us about nine very tiring hours to get to the camp - though the end of the cave is easy, the first five hours are very hard work. This is followed by a long section where you are at least on top of the rocks, but boulder hopping when the boulders are the size of mini-metros, loosely stacked, with the more than occasional view down to the stream 60 or 70 feet below, can be hard work. In the wetsuit, I was fairly steaming.
Drinking water is scarce as the main stream is a sewer.
I wish I has photos of the line of five bright lights swimming down the dead straight canal, but I won't forget it. The boulder climb up to the camp area was nasty, covered in slippery mud. The campsite was a bit squalid, but many cave camps are. Well, went to shiver, toss and turn in a rather damp sleeping bag. The cave stopped feeling warm, and I started feeling cold.
