This is a tree climbing cache. You can tree climb to it, but it would probably be accessible if you bring a ladder.
When I was in K-5 at the school here, I would always climb this tree. Now, I am bringing other cachers to it. Good luck!
During weekdays (not summer) at certain times there will be kid-muggles out here at certain times. I tried to place a different cache here a while back, but a kid stole it before it was even published. This one is hidden better.
