Climber is a skill that can be given to a Lemming. It is the first of the eight skills available in Lemmings, as well as the Classic Tribe in Lemmings 2. Climbers can scale vertical walls no matter how high, but will fall back down if they hit a ceiling. The climber is a permanent skill - once assigned to a lemming, it has that skill for the rest of the level.
- Climbers often work with Floaters, in which case the Lemming becomes an Athlete.
- In the 2006 remake, climbers are distinguished by wearing orange helmets.
