Boultons Crossing Reserve, also known as Gumma Reserve Camping Area, sits on the banks of Warrell Creek near Macksville on the north coast of New South Wales.

The reserve includes a boat ramp, making it one of three water-access points along Warrell Creek within Gaagal Wanggaan (South Beach) National Park.

The boat ramp is well suited to fishing and paddling, with Warrell Creek offering calm waters for canoeing and kayaking. The creek flows into the Nambucca River approximately 9 km downstream.

The access road in the final stretch is unpaved dirt, and the area can become muddy after rain, which is relatively common in the region, particularly in late summer and early autumn.
