Lledr Hall is thought to have been built c. 1936 using the timbers of the Pavilion of the Blaneau Ffestiniog Eisteddfod of 1899. A wooden structure, it is 2-storeys with white painted cedar shingles to the walls, an hexagonal corner tower and black and white decoration to the first floor. It was a Countrywide Holidays Association (CHA) hostel until 1962. Now in use as an outdoor pursuits centre.
