Coal Pit Spur Loop

Cross the creek right by the car park. Head up the track (Coal Pit Spur) which vaguely follows the pylons uphill initially and across an open scrubby area before dropping south into beech forest. Switchbacks take you down into the valley then up alongside a creek, before climbing up the other side with several more switchbacks. Its a long steady climb through beautiful beech forest.
After about 4km you reach the Craigieburn ski field gravel road. Turn right and head up here for about 500m until you see the DoC sign on the left heading back into the beech forest, signposted Lyndon Saddle.
Follow this track as it sidles up through the trees, then turn hard left at the junction just before the 6km mark, again signed Lyndon Saddle. Keep climbing gradually until you pop out on the saddle. From here the 10 minute detour up Helicopter Hill provides expansive views across the area.
From the saddle follow the track downhill towards the Craigieburn campsite. Just before you reach here keep left onto the Sidle 73 track.
This clubs briefly through beech forest before popping into pines. You then meet the ski field gravel road again - keep left and head uphill for 500m before meeting the track you arrived on - signposted to Coal Pit Spur.
From here follow the track back the same way to your car.
