A Ladder is a wooden block used for climbing walls and blocks either vertically or horizontally.
Ladders allow a player to climb vertical surfaces. A player must place them vertically on a block. After it is placed, it can be climbed by pressing the 'forward' button while touching the ladder. Ladders can be built with 7 sticks, by building the form of a ladder in the Crafting Table. a player gets three ladders every time they craft it.
In order to craft a ladder, a player needs 7 sticks.
Ladders occur naturally in Strongholds, library rooms, and intersection rooms with a wooden ceiling. Ladders can also be found in NPC villages, specifically, in tall buildings and houses with roofs which have fence railings.
Like torches, a ladder occupies one block from the side on which it is placed and cannot be placed on glass, leaves, ice, or glowstone blocks. Unlike torches, however, they resist water and will create an air pocket, like Signs, meaning that they can be used in gravel elevators. They also resist lava, and can be used instead of glass to let lava light shine through a ceiling. If a player places a ladder in lava or water just on the ground and not near a wall, the air pocket will be present, but invisible.
- Placing ladders on snow layers make the ladder invisible, but they still act as if a player placed them normally.
- If a player places a Bucket of Water in a place occupied by a ladder with no other Blocks next to it, the water will replace the ladder, and a Player will not get the ladder back.
- Attempting to place a ladder on a spot another ladder occupies may instead place the ladder somewhere nearby.
- It is possible to remove a ladder while standing on a ladder and holding the (on PC) to sneak, but it can take a long time because the countdown for breaking the ladder often resets.
- Ladders that are one block higher than the ground level a player is on can only be reached by jumping up.
- Some mobs are able to climb ladders such as the Creeper.
- Ladders can be used to allow a player to scale vertical surfaces upwards or downwards in a manner that minimizes most mobs' abilities to follow them, although it's best to be cautious when heading up an exposed ladder because Skeletons can still shoot a player down.
- Ladders can be used as fuel, smelting 1 1/2 items per ladder.
