From Adelaide CBD take Main South Rd for about an hour passing through towns like Marion, Noarlunga and Seaford, in that order. About 5 minutes out of Seaford providing you’re still on Main South rd turn right onto Maslins beach Rd. At the next major intersection turn left onto Old Coach Rd. Take this rd for around 5 minutes. Turn right onto Tuitt Rd. At the end of Tuitt Rd turn left and then right at the very next road and head towards the car park. From the car park head towards the ocean while going right along the cliff top. Its the very last headland and has a rock(gulls rock) 10m (33ft) offshore which is easy to spot.
Be warned the beach visible from the jump spot is a nudist beach.
