There were mountain accidents in Snowdonia long before there was an ‘official’ mountain rescue team, with ad hoc rescue parties pulled together at short notice by Chris Briggs, the owner of the Pen y Gwryd Hotel, a designated Mountain Rescue Post. But it was March 1973 before Llanberis Mountain Rescue Team (Tim Achub Mynydd Llanberis) was recognised by the then Mountain Rescue Council (MRC) with a formal constitution. Three years later, the Warden Centre at Nant Peris was also formally recognised by the MRC as Rescue Post 77. Llanberis is now the busiest team in the UK, often dealing with several calls for help in one day and, in 2019, recording over 200 incidents.
