Trewalla Camp is an overnight walkers camp on the Great South West Walk, situated within Discovery Bay Coastal Park in Victoria, Australia.

Set just back from the Southern Ocean swells of Bridgewater Bay, the site occupies a sheltered position among coastal scrub. A small lookout nearby offers scenic views across Bridgewater Bay.

The camp is a stopping point between The Springs Camp and Mallee Camp and provides a shared shelter, table, toilet, and a shared fireplace, though fuel stoves are preferred by Parks Victoria.

Seasonal tank water is available but should be treated before drinking.
