Rope would be an item that can be used to climb down cliffs. 1 Rope (they shouldn't be stackable) will equal six blocks' worth of climbing. You can use one a few times before it breaks, and you throw them over the cliff by right-clicking them. They should be tied to a post like a lead, and when you climb down them, they work like a ladder.
