Boulder Adventures' Bryn Du Mountain Centre is in Llanberis, Snowdonia. Bryn Du is a spacious Victorian house in its own gardens, which we have refurbished as a specialised base for outdoor adventures.

The accommodation

The centre has 35 beds split over seven bunkrooms. We have one room for 1, two rooms for 4, three rooms for 6 and one room for 8. Bedding is provided for all who stay in the centre but we do ask guests to bring their own towels. Shower and WC facilities are provided in one area comprising 6 cubicles containing a shower, WC and basin and 1 cubicle which contains only a WC and hand basin.

The lounge gives you the chance to recover from your day's activities and the dining room is an ideal spot to socialise and refuel, enjoying the fully catered meals that we can provide. There are also modern shower facilities and an efficient drying room. The gardens offer a camp fire area, giant chess board, table tennis table and wooded hillside.

If you are not on one of our adventure courses it can still be possible to stay with us on a bed and breakfast basis. For bed and breakfast bookings final entry to the building is by midnight at the latest and we serve breakfast at 8am.

Room 3  - Capacity 6 with 2x single 2 x bunks
