Castle Gorge Camp Site sits on the Maretlwane private game conservancy on the Northern slopes of the Magaliesberg range, roughly 35 km west of Hartebeespoort Dam in North West Province.

The Maretlwane River, which has its origin at Castle Gorge, flows through the length of the reserve. Two sets of camping facilities are available on the banks of the Maretlwane River. The sites have no electricity and make use of shared ablution facilities.

Bookings are essential, as Maretlwane is private property. The reserve is a popular base for hiking to Castle Gorge, an approximately 8 km moderate-to-challenging trail featuring steep and rocky terrain, dramatic gorges, waterfalls, and natural pools.

Wildlife may be encountered along the way, and guided hikes are available.
