The Tia River has a more reliable flow than the nearby Apsley, with a catchment in Mummel Gulf NP and Riamukka State Forest. The Tia Falls track along the eastern side of the valley offers a good view of the falls which drop 100 metres into a gorge, and is easily walked in 30 minutes. At the Gorge lookout, at the end of the walking track, you may see wedge tailed eagles hovering on the thermals. The Tia flows into the Apsley, and eventually into the Macleay River.
The longer Tiara Walk crosses the river on a footbridge and leads to a lookout on the western side.
