The R304 is a Regional Route in South Africa that connects Stellenbosch with Atlantis.

[1] Its north-western origin is a junction with the R307 (Dassenberg Drive) adjacent to Mamre Nature Garden north of Atlantis (south of Mamre).

It heads south-south-east as Charel Uys Drive to enter the centre of Atlantis, where it becomes Reygersdal Avenue towards the east-south-east before bending south.

After 10 kilometres, the R304 reaches a t-junction, where the road southwards becomes Old Mamre Road and the R304 turns to the east via a left turn to cross the N7 highway and enter the village of Philadelphia.

The route proceeds south-south-east to end at a junction with the R44 and the R310 in Stellenbosch (north of the town centre).
