This track is part of the West Coast Wilderness Trail (Ngā Haerenga New Zealand Cycle Trails).
Starting from the car park off the Woodstock Rimu Road, the eastern end of the walkway leaves the road and joins a historic logging tramline which is followed for the rest of the trip.
After a straight flat section section, the track climbs gradually around the side of a small hill before reaching the turn-off to Picnic Point. The track to Picnic Point is a side trip to a small pebbly beach on the edge of Lake Mahinapua which is about 15 minute walk from the turn-off. Picnic Point and return to the carpark is about one hour and is a popular walk for those not wanting to go along the whole walkway.
Soon after the turn-off to Picnic Point the tramline leaves the scenic reserve and crosses a creek into Mahinapua Forest. This area was commercially logged before being grazed for a short time. It then became an experimental forestry station and was logged again in the 1970s.
The track continues through the forest before descending around the side of a small hill to lower lying land. Elevated board walks are used to cross this swampy area, which floods regularly. After crossing this swamp the track sweeps around to the site of the Mananui Sawmill that was started in 1885. From here the walkway crosses Mahināpua Creek and its swampy margins via a foot bridge and through a privately owned deer farm, before emerging on S 6 just north of Mananui bush.
This track can be mountain biked, and it is relatively straightforward.
Access is from a signposted car park approximately 8 km south of Hokitika on SH6 or from a car park on the eastern side of Lake Mahinapua on the Woodstock Rimu Road. The walk can be done from either direction.
After heavy rain, water may rise and cover the boardwalk so it becomes impassable.
