Black Box Campground sits within the Lyrup Flats section of Murray River National Park in South Australia, on the floodplain along the northern side of the river near the Lyrup ferry.

It is one of two designated campgrounds in Lyrup Flats — the other being Colligans — and is well suited to caravans and larger groups. The area is accessible by 2WD in dry conditions.

The surrounding floodplain offers birdwatching, fishing, and riverside camping, with long-drop toilets located at various points within the park. Campsites are unpowered, and campfires are prohibited during fire danger season. Dogs are permitted on a lead.

Visitors should be aware that lace monitors have been spotted around Lyrup Flats campsites and should be treated as wild animals.
