From L'Agulhas, it follows the coast east to nearby Struisbaai. The roads then heads north and inland, bypassing Hotagterklip to the east. Near Bredasdorp it receives the R317. The routes enter the town together where they meet the R316. The R319 is the first to diverge on the other side of Bredasdorp and heads north-north-east to its terminus at the N2.[1]
