It's always best to do a good inspection of any tree you want to climb. Our article, "A Climber's Guide to Tree Inspection," is an excellent resource for how to accomplish a thorough evaluation.

Obviously, if the tree has obvious danger signs, don't climb it. Also, do not climb a tree that shows any signs of wear or weakness. Do that tree a favor. Get some help so you can restore it to health. Ask a certified arborist for suggestions and/or assistance.
