A beaut walk in kauri forest, from the Cascades carpark. A good introductory tramp in a half day. Take your niece or nephew. Hug a kauri tree, ogle a dam. There's some interpretation info along the way
Either way is good; the loop takes you via the Cascade track, Fenceline Track, Long Road track and Upper Kauri Track.
Nice view of a dam along the way. You can make it longer by extending down to include the RGB, Chateau Mosquito and Sissam tracks (extra 6k all up) if you like.
