You can now see the caldera shape that gives this track its name! Continue w through a gate and follow the saddle to the next peak,the track narrows here,At the top of the next rise I call this Beardy,s Camp.Great veiws of the city skyline.Continue untill you break from the bush into a large clear y junction.Back on to fire trails.Follow the trail to the right down hill.(Left will take you to white rock).Pass through another gate on your left is keyhole cave.The next peak is Spring Mt to ascend leave the fire trail and skirt around the base heading sth.the trail appears to end.Start heading up here to a small cave.Skirt left of the cave and pick your way through the boulders till you reach the summit.Dont go to far left if it feels a bit airy head back towards the cave and straight up!Enjoy amazing 360 dgree vews.Take care there are some large and slippery rock faces up here!To descend retrace your steps,back to the fire trail! Follow the trail to the left downhill till you come to a point where the trail drops steeply,look to your right and find the lonley boulder.There is no obvious track here so a little navigation skills will come in handy.I call this" The Dragons Spine Trail ".The next landmark is the point an easy scramble down ,just stay on top of the ridge to get down to a wide open grassy saddle.Follow this stay high L or R of you drops down into gullys.soon you will start to see a rocky ridge heading left follow this , staying as high as you can .You should start to imagine why i call this the dragons spine!

Retrace your steps 20 m or so to the Stegasaur and scramble down through a gap in the rocks.1 level,and keep t rex on your left.you can climb under this formation here.Continue uphill from here up some bouldery skree Always staying high.Drop gently off this plateu into a grassy saddle,follow the ridge untill it rises to a scrubby plateu,stay up untill you come out at the fire trail again beside the highest electricity tower.Follow this track to the right weaving your way down hill to the bottom of a gully and a track intersection,go right.you will cross a creek and come across a spring mt gate on your right.You can go back this way but i keep going to the next gate #6.Turn right here and head steeply up hill.At the top of the hill the track seems to head left stay right.At the next junction stay left.The track on the right heads back down to the spring mt gate you passed before gate 6.You are now on the track back to where you began ignore any L or r trails till you see the spring mt forest park sign take the next left when you can see the wate tower back to thornbill drve.


Nice walk, challenging sections. I took the advice of other comments and used Wikiloc for navigation and it made it a lot easier. 14km, 3hrs 45 mins, 600m elevation gain.

Good map recommended as there are lots of named and unnamed trails.

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
