Excellent walk 4 1/2 hrs return with Kwaka 14 km views to border ranges and Toowoomba range

A nice walk. Convenient to Brisbane. A good amount of trail and off trail hiking. Navigation made much easier with a GPS. I walked on the first day of spring and it was getting hot. I don't think it would be pleasant in summer. I made a shortcut, dropping down the ridge at 880556 (-27.70416,152.88644). All up 12km and just under 4 hours, with a stop for morning tea.

Great walk.

It is certainly not 26km! The problem is that there is an extra GPS location on the GPX track. One you remove that, it goes back to 14km.

I walked the Spring Mountain Caldera circuit for the first time today. Total distance seems to be about 14-15km. I think it is optimistic to call the section between Spring Mountain and the Yuddumun Trail a track, it was entirely off-track with only vague signs humans had ever passed (like a muesli bar wrapper at the formation the OP called the T-rex).

Otherwise I had a good walk. GPS was very unreliable, but stuck to the ridge as much as possible and it all worked out.

Did this from Springfield. Measured at 14km and took just over 3hrs. 26.5km is an over-exaggeration

Do this every year with the Australian Air Force Cadets. A great day out. The view from Spring Mountain is fantastic
