Rocky Bar Gap is a campground on the Larapinta Trail in the West MacDonnell National Park, Northern Territory, situated beneath the towering flanks of Mt Sonder.

Hikers reach it after crossing the sandy bed of Davenport Creek and climbing a low rise before descending into the gap — a stretch of roughly 19 kilometres from Hilltop Lookout on a typical day's walk.

The campground sits within the national park and offers basic facilities including a drop toilet and water tank.

Some hikers opt to camp in the dry creekbed at either end of the gap rather than the designated site itself, though doing so puts them around 400 metres from those amenities.

The surrounding terrain features spinifex plains, mulga, and mallee woodland, with Mt Sonder's massive form dominating the skyline.
