The track starts at the boat launching site opposite the Lake Brunner Lodge at Mitchells, on the southern end of the lake.
It follows a boardwalk through wetlands and around the lake shore to a secluded camping and picnic area at Bain Bay. Parts of the track also pass through dense forest containing kahikatea, matai and rimu, and tall tree ferns.
Both track and boardwalk can be immersed and impassable when the lake level is high.
About halfway around, a double row of piles in the lake are the remains of an old L-shaped wharf. There are also remains of tramways and other equipment that delivered logs to be towed across the lake to a sawmill at Te Kinga.

Follow Lake Brunner Road to Moana, or turn off at Kumara-Inchbonnie Road to get to the south and west of the lake and back to Kumara.
