Track begins from the hut side of the bridge (true right) and is a very picturesque track following the Waingawa River to Mitre Flats. Undulating with plenty of roots and side streams to cross. Quite a bit of recent windfall as of Oct 2017 - most easily negotiable, although one creek bed near S40° 47.792' E175° 29.333' requires some care to get in and out of (mind the onga onga), and another scramble down the bank above a decent blockage at S40° 48.625' E175° 28.981'.
DOC signage/ website recommends 3.5-4 hours, but I would suggest allowing at least 4-5 in current condition.
