A group on mainly Westerford High School families set out to visit "The Waterfall" on the first day of the Otter Trail. Along the way we stopped to investigate the Guano Cave. Towards the back of the cave, past the first pool, there were about 20 Rhinolophus roosting on the walls and roof of the cave.
Our visit disturbed them so photography became a little difficult, although I did manage to get a good image of a bat's bum!
