Ysgol Hafod Lon is a special day school that is situated on the outskirts of the village of Penrhyndeudraeth. It is one of two special schools that are maintained by Gwynedd local authority. Nearly all pupils have a statement of special educational needs or an individual education plan. The school provides for a wide range of additional learning needs, including severe learning difficulties, profound and multiple learning difficulties and autistic spectrum disorders. There are currently 110 pupils between 3 and 19 years old on roll. Most pupils come from the Meirionnydd and Dwyfor area and a very few come from the Arfon area and nearby local authorities. Around half the pupils speak Welsh at home. Approximately 36% of pupils are eligible for free school meals. Very few pupils are looked after by the local authority. Since the last inspection, the school has moved to a new site. During the last fifteen months, pupil numbers have increased significantly. This means that there has also been an increase in the number of staff who work at the school and, during the last two years, the school has developed a new leadership structure. Ysgol Hafod Lon is currently a lead creative school that is working with creative practitioners. The headteacher has been in post since September 2004. The school was last inspected in December 2010.
