Campsite 20 is one of a series of sites spread along Katarapko Creek, part of a larger camping area within the Katarapko section of the Murray River Parks in South Australia.

Sites 19 through 55 line the creek, which branches off the Murray River and rejoins it at the far end. The creek is generally quiet, as submerged trees limit boat navigation to a kilometer or two, meaning most watercraft passing by are canoes or kayaks.

All campsites in the area must be booked in advance through Parks SA. Note that some sites are permanently closed and others may be closed periodically for maintenance.
