Mount Sunday is a stunning site with expansive views of the Rangitata River and the surrounding mountains.
The small hill got its name because boundary riders from the high-country stations would meet here on Sundays. More recently it was the film site for Edoras in the movie The Lord of the Rings: The Two Towers.
The track starts on Hakatere Potts Road, about 48 km west of Mount Somers. Leave Mount Somers on Ashburton Gorge Road, which becomes Hakatere Potts Road.
