South-west of Stanthorpe is the rugged Sundown National Park – a contrast to the rounded giant ‘marbles’ of Girraween. This is a wilderness park hidden in the Severn Valley to the west of the New England Highway.
The Severn River weaves its way through the park’s ancient rock, forming spectacular sharp ridges and steep side gorges. Access is from three directions. About 5km from the 4WD-only entrance via Ballandean, side track leads to the stunning Red Rock Gorge where 50m waterfalls tumble over cliffs stained red with lichen.
There are two all-vehicle entries that can be found south from Nundubbermere Road to Nundubbermere Falls and east from Glenlyon Dam Road to the Broadwater camping area.
