There's a good chance that most of us have climbed trees before as children, maybe even as adults as well (more times than we want to admit). Climbing trees can be both fun and exciting. For this challenge, you must have found at least 25 caches with the Tree Climbing Attribute that have a terrain rating of 4 or higher. Also, of the 25 caches, at least 1 has to be a traditional, multi, puzzle, and letterbox. Since this is a tree climbing challenge, you will also have to do some climbing to reach the cache (though you cannot use this as your 25th cache)!
