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. The invention also includes an offset tree stand configured to be attached to the top of the vertical support columns. Once attached, the tree stand and ladder become one integral unit. This feature allows the vertical support columns and tree stand to be assembled on the ground, then pivoted up against the tree. The user can then secure the ladder to the tree as he or she climbs.
