The trail commences at a junction with the East Gippsland Rail Trail beside Seaton Track in the Colquhoun State Forest.
The Discovery Trail heads south on a narrow path through the eucalyptus forest, while the Rail Trail travels east-west on a wide clearing following the route of the former Orbost railway line.

The trail initially travels close to the route of Seaton Track, but their routes soon diverge and the trail continues south through isolated bush.
The track surface is coarse stony gravel in this section, much of it formed from crushed granite from the quarry.
Parts of the trail in this section are narrow, with some very steep grades, and should be approached with care.

After 4 km the trail descends steeply to Quarry Road and travels beside this for a short distance, before offering a detour to the granite quarry near Mississippi Creek.
This quarry is now abandoned, but operated during the first half of the twentieth century originally to provide granite used to build a permanent entrance to the Gippsland Lakes.
This was to be a replacement for the timber pylons that had been used in the original construction of an entrance, but which had suffered much damage due to the marine toledo worm.
There is a small viewing area and rest stop at the quarry.
