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.
The route continues south towards Galway Bay, turning west to the follow the north shore and passing through An Spidéal (Spiddle) before reaching the suburbs of Galway itself. It takes the coast road through Salthill up to the city centre, crossing the River Corrib by the Spanish Arch.
The last section of the R336 runs out of Galway along Bohermore and Tuam Road (the former route of the N17) as far as a signalized crossroads junction with the N6 and N83 on the northeastern edge of the city.
