Foxes Lair has three picnic areas and five walk trails.
- The Banksia, Breakaway and Valley circuits are centred on the Marri picnic area.
The Claypit Circuit is centred on the claypit picnic area.
The Granite Trail can be accessed from the Arboretum picnic area or the Range Road car park.
Breakaway Trail is a 400 metre 10 minute walk. Take a gentle stroll through lateritic gravelly soils to a large breakaway with a view of the Narrogin valley. Parrot bush is very common underneath the marri and wandoo trees. Brown mallets line the breakaway slope.
Valley Loop is 1400 metres long, and takes about 20 minutes. It goes down to a shady sheoak valley below the Breakaway Trail and has orchids and other flowers, which persist longer than other walks. Check out the stark white spider orchids in early September.
Banksia Trail is 1950 metres long, and takes about 40 minutes. It features gravelly upland soils with marri- jarrah- wandoo woodland and proteaceous kwongan heath. A great diversity of wildflowers can be seen from August to October.
The Granite Trail is 1560 metres long, and should take around 30 minutes. The Aboretum is in the first section of the Granite Walk. It features over 70 species of eucalypts. You'll pass through a beautiful York gum -wandoo- sheoak woodland with large granite rock outcrops. Look for the growth of trees between the rocks and the characteristics of the granite caused by surface weathering. Children can fossick for spent bullets at the old rifle range butt.
The Claypit Circuit (1920 metres 40 minutes) traverses a range of landcapes and soil types and features wildflowers not found elsewhere in Foxes Lair. These include Leschenaultia formosa (Red leschenaultia), Banksia fraseri, Calothamnus quadrifidus, Calytrix leschenaultia and Petrophile heterophylla. There are some steep slopes with stairs up breakways that offer a glimpse of Narrogin town. Late afternoon sun 'paints' the trees gleaming copper and silver, this is a good time to see grey kangaroos.
