Blowhole Beach lies at the western boundary of the park. Access is via a steep four wheel drive decent to a car park on the eastern headland, otherwise there is car parking at Cobblers Hill two kilometres inland.
The beach lies at the base of a steep valley with a creek draining across the eastern half of the beach, and with headlands and rocks extending 100 metres seaward. The sandy beach is 120 metres long, with a 70 metre wide bar that usually has a permanent rip against the western rocks which can be hazardous, particularly if there is also surf.
Blowhole beach is unpatrolled and care should be taken both accessing the remote area and when in the water.
