This is a mixed-use track that climbs to 1310 meters (the summit of Mount Dewar) which is less challenging than you may think considering that you're starting at 1200m in height when you join the trail but those who struggle at higher elevations may need to take it easy.
The best place to access this trail is via Skippers Saddle car park (off of Coronet Peak Rd) and take the Devils Creek track (an old 4wd track) to the access point of this track.
