Campsite 18 is one of 18 individual, secluded campsites situated along the Murray River within the Katarapko section of Murray River National Park in South Australia.

It marks the last of the river-frontage sites before the campground continues along Katarapko Creek from site 19 onward. Like other sites in this section, it offers shade and the ability to launch canoes directly onto the river.

Walking trails nearby explore the area's wetlands, European heritage, and Aboriginal history. Dogs are not permitted within the Katarapko camping areas.
