Start this track at Te Wanahu Flat.
The early part of the track passes through Mills Bush,16.2 hectares of virgin podocarp forest containing giant lowland tōtara, mataī and kahikatea trees, many of them probably 1000 years old. Their roots are spread across the path. Ferns abound along the walk – most of the 68 species of ferns in Peel Forest can be seen along the way.
Look out and listen for bellbirds/korimako, riflemen/tītitipoumanu, grey warblers/riroriro, tomtits/miromiro and silvereyes/tauhou.
Due to storm damage a boardwalk on the Fern Walk has been removed. A minor stream crossing is now required.
