A Simm is a hill in Britain at least 600 metres high with a drop of at least 30 metres on all sides. Ten people are known to have climbed all 2531 Simms, including five in 2023. Anyone who has climbed at least 2000 Simms is eligible for the Simm Hall of Fame. As this is a distant target for many, the Simm Corridor is open to those who have climbed at least 1500 Simms.
