Swan Lake Campground is a small coastal campground set within Discovery Bay Coastal Park in south-west Victoria, located between Portland and Nelson near the South Australian border.

The campground offers five sites, each accommodating a maximum of six people, and is nestled among a significant coastal dune system.

A walking track leads from the campground through expansive, mobile sand dunes to a surf beach, while Johnstone Creek and a small waterfall lie upstream of the lake.

Facilities are basic, including pit or composting toilets and bore water that requires treatment before use. Bookings are managed through Parks Victoria.
