A portable ladder for securing to an object, such as a tree, is provided. The portable ladder includes first and second vertical supports, each with a channel extending therethrough. The vertical supports can be coupled together to form a ladder segment. The portable ladder also includes a plurality of steps coupled to the first and second vertical supports, and a primary strap extending through the channels in the first and second vertical supports. The first end of the primary strap extends out of the channel in the first vertical support and is configured to be wrapped around the object to form a strap loop, and the second end of the primary strap extends out of the channel in the second vertical support. The portable ladder further includes a locking device configured to lock the first end of the primary strap to the first vertical support, and a ratchet mechanism configured to be coupled to the second end of the primary strap to adjust the tension in the primary strap to tighten the strap loop around the object. Methods of securing the portable ladder to an object are also provided.
