An easy loop trail with easy access from the Holdsworth carpark.
The track starts from the end of Holdsworth Road.
The track to Donnelly Flat passes through some of the best mixed podocarp/broadleaf forest in the Tararua Range. Rimu, miro and northern rata tower over a canopy of kamahi, red beech and silver beech. Donnelly Flat is an attractive picnic and campsite.
The 1 km nature walk is through the forest above the flats to rejoin the foot of the Gentle Annie Track.
