Bat fact 1: you can hear the sounds that bats make (if you have good hearing), but only their social vocalisations: it is their echo location sounds that are too high for the human ear. Bat fact 2: they can see just as well as you or I (but not in total darkness – that's what the echo location is for) so the saying “blind as a bat” is way off the mark.
The cache is close to, but not in, the hide. Please don't try to enter it. Big thanks to Lindsay and her team from the Wildlife Trust for permission to place this and the other caches here.
