This is a much smaller arch than the Oparara Arch but is arguably the prettiest. It is reached after a 15min walk through rain forest before reaching the access point to descend under the arch to the river below.
Returning to the track junction, you can then follow the path over the top of the arch where for a short distance there are paving stones, some with "moa" imprints. This is part of a loop track taking in Mirror Tarn with a time of about 1½hrs for the loop or you can continue on to the Valley Track.
Please use the hint as GPS readings can be quite erratic with the bush cover. If anyone has better coordinates please don't hesitate to post them, thank you.
