A ladder is provided having a securing apparatus for securing the ladder to a horizontally extending support structure (e.g., a utility cable), a vertically extending support structure (e.g., a utility pole) or both. In accordance with one embodiment, the securing apparatus includes a pair of spaced apart engagement mechanisms, wherein each engagement mechanism is pivotally coupled with an associated rail of the ladder. Each engagement mechanism includes a frame member, an engagement member pivotally coupled with the frame member and a pole grasping structure coupled with the frame member. In one embodiment, each engagement member is configured to rotate from a first position, wherein an open gate is formed between the engagement member and its associated frame member, to a closed position.
