Deep inside a dark cavern, beyond the clump of white willows, lies a secret hiding place. Find it if you can.
This is no more than terrain 3 if you're comfortable with downclimbing, but since many people aren't, I'm marking terrain as a 4.5. Please be careful on the way down after the find!
Ropes or spelunking gear not required, although a headlamp / phone torch might be useful.
