Although I dislike crowds and avoid them, they can sometimes be helpful or useful. After having photographed the bubbling small mud volcanoes, I would have given this big guy a miss had I not overheard the other guide telling his group that this was the biggest and most spectacular- and dangerous of them all, as with minimal water, it could go off any time. I had not been inclined to climb it. Well, after that group had moved away after making a fuss over it, I climbed up there myself and am glad I did! This was the largest and most spectacular of them all, with the mud in it almost to the consistency of sludge. Less water means more chance of eruption- it fortunately didn't, although the other guide was telling his group to be careful!
