This is Snowdonia's Original Bunkhouse, which I started in 1966. You need your own sleeping bag, but not pillow. (Teddy bears come free). It's all self-catering, in several grades of
accommodation with helpful flexibility, as a base for your activities. There's the Main Bunkhouse sleeping 21, The Flat for 4 or 5, Castell Gwynt sleeping 7, and The Bedshed, sleeping 8.
All are equipped for cooking and dining, except The Bedshed, which might share the kitchen in either The Bunkhouse or The Flat. All sections have showers and toilets. Details are shown under
"Accommodation", which gives room capacities if gender segregation is required. The 9 and 8 rooms in the bunkhouse are a mix of double and single mattratzenlager - old Alpine style.
It's warm enough and friendly, and I live on the premises, as a retired instructor/guide/ rescue leader and "Mr Fixit". It's not conventionally "modernised" and has always been known as
"A Centre of Lo-Tech Pragmatism" - keep it simple so long as it works. It certainly does here - come and see !
