Since 2003 Boulder Development has delivered courses from the Bryn Du Mountain Centre, nestled in the village of Llanberis at the foot of Snowdon. The centre can sleep 35 in very clean and tidy bunk rooms. We have 7 bunkrooms which range in size from 1 to 8 beds. The centre has a comfortable lounge with wood burner, effective drying room and modern showers. The centre can be offered on a bunkbed and breakfast basis, fully catered or as a self catering property.


The Bryn Du Mountain Centre is very popular as a base for groups taking part in events such as the National 3 Peaks, Welsh 3 Peaks or Welsh 3000s. The centre has proved ideal for our apprentice training courses as well as our Prince's Trust Team Programme residentials.


The centre is in walking distance of the village of Llanberis, routes up Snowdon and other peaks like Moel Elio and the Glyders.
