Leads from Crabtree up to White Timber fire trail, which Joins onto Jeffries track. This is near the top, lower down the track is overhung by tree ferns and can be damp and slippery - worth wearing a long sleeve jersey as the ferns can slice your arms up! Connecting fire trails go up to Big Bend near the Mt Wellington summit, via Collins Bonnet. Best done starting from Big Bend as maximises your altitude drop (assuming you have done a car shuffle!).
