Granlahan National School is a five teacher school (3 mainstream, 1 Autism Class and 1 SET) situated in the most westerly corner of County Roscommon, between the towns of Ballyhaunis in Mayo and Castlerea in Roscommon. The school is very well presented with great facilities such as basketball court, school football pitch, games area, a large playground area, outdoor classroom and a Sensory Room. We are delighted to add an Autism Class to our facilities. In September 2024 we opened the doors to our Suaimhneas Room to cater for children in our locality with Autism.
