The R336 is an L-shaped route which crosses a large part of County Galway.
Starting on the N59 in Leenaun, on the shore of Killary Harbour and the northern edge of Conamara, it heads southeastward into the mountains before descending to meet the R345 by the Bealnabrack River. From here it runs southward to Maam Cross, where it meets the N59 again.
