Greenclose House has been the headquarters of the Northern Pennine Club since the mid-fifties, and was purchased in 1967 (having previously been leased). It is a stone-built farmhouse just outside the Yorkshire Dales National Park. A large Common Room is adjacent to the kitchen (bottled gas cooking), and a recently enhanced extension houses tackle store, drying room, showers and toilets. A smaller quiet room forms the library, with extensive collections of caving literature and surveys. Upstairs are four bedrooms with bunk bed accommodation, one room specifically designated for guests.
