    Abstract: A portable modular ladder which can be attached to a vertical object to be climbed—such as a tree. The ladder's structure is preferably provided by two or more vertical support columns locked together. These vertical support columns can be secured to the object to be climbed by a securing strap or other conventional means. A set of rungs extend outward from the vertical support columns. These rungs are optionally made removable, so that a user can remove the rungs and leave only the vertical support columns in place.
