Early start. The walk starts at the car park at the top of the T3 track near Mountain Lagoon. We head west along a rocky ridge, then north west to an unnamed peak that has great views over D’Arcy Range and Colo River. Next, we head north east, following a ridge down to Tootie Creek, joining it by some excellent rock platforms and pools. We follow Tootie Creek down to the junction with Colo River. This alternates between open rocky platforms and bush bashing. On arriving at the Colo, we return up the T3 track to the car park. Around 8 hrs. Bring 2 litres of water/electrolyte.
