The Great Dividing Range also swings south here and follows the border out towards Sundown National Park. The Main Range is regarded as the best extended walk in south east Qld. It crosses over Spicers Peak, Doubletop, Mt Huntley, Asplenium and Mt Roberts. Mt Superbus, SE Qld's highest mountain lies just off the rim to the south. The rim proper heads over Mt Roberts and across to Mt Bell and Teviot Gap, the head waters of the Condamine River.
Most walkers avoid the logging regrowth around Mt.
Bell and use Mt Superbus and the old rabbit fence to Teviot Gap. The border follows the McPherson Range from Wilson's Peak through to Tweed Trig. The Trig marks the point where the McPherson Range and the Border meets the escarpments of the Tweed Ranges, the caldera of Mt Warning. From Wilsons Peak the fence and track continues through to the Boonah border gate, then heads up Mt. Clunie and swings around back to Mt Ballow.
