The slopes of Holme Fell include the massive disused green slate quarry at Hodge Close, located at . The quarry closed just before the start of the Second World War. It has flooded chambers and tunnels which are used by cave divers for sport, but it is a dangerous location and several divers have died over the years, after becoming lost in the murky waters of the tunnels. The quarry is also used by rock climbers and offers some excellent Extreme routes such as ‘First Night Nerves' and ‘Wicked Willie'.
