Milnerton lies on the Western Seaboard of Cape Town, also known as the Blaauwberg Coast, just north of the city along Table Bay.

The water is generally cold as a result of the Benguela current that flows along Africa's western shore.

Every Wednesday during summer the surfski and stand up paddlers use the SE winds and race the Downwind Dash series to Big Bay beach.

The N7 (Cape Namibia Route) is the main highway bisecting Milnerton, running north–south from Malmesbury to Goodwood and passing the interchanges at Bosmansdam and Plattekloof Roads.

The N1 highway borders Milnerton to the south, passing Century City and Paarden Eiland and runs east–west from Paarl to Cape Town.
