Lake Mombeong Campground sits within Discovery Bay Coastal Park in south-west Victoria, roughly midway between Portland and Nelson near the South Australian border.

The campground occupies a flat, grassed plain beside a tranquil, shallow freshwater lake backed by coastal dune vegetation. Sites are grassed with fire pits, and shade varies across the grounds.

The area is known for swimming, snorkeling, kayaking, fishing, short walks, and wildlife viewing. Facilities include flush toilets and picnic tables. Access is via Lake Mombeong Road off the Portland–Nelson Road, with a 4WD recommended. Dogs are not permitted.

Bookings are managed through Parks Victoria.
