Estimated Times to Run







Opened by Sir David Bellamy himself, the Oparara Valley Track is one of the most beautiful - and sadly less-frequented - trails in New Zealand.
It is worth a bit of zig-zagging to make the most of this stunning area, so first drive to the Box Canyon/Crazy Paving Caves to look for the rare Spelungulae cavernicola (Nelson cave spider).
Return to the Oparara carpark and warm up with a quick out-and-back to the largest limestone arch in the Southern hemisphere - the Oparara Arch Track leads directly west out of the carpark.
Returning to the carpark, jog back up the road (north) and take the Moria Gate/Mirror Tarn Loop Track (approximately 600m up the road on the right). Follow this beautiful loop track around Mirror Tarn: at the junction with Oparara Valley Track you will discover picturesque Moria Arch. Cross over the top of the arch (follow the Moa prints) and climb down under it for beautiful imagery.
Return to the junction with Oparara Valley Track, head south and float along mossy trails and through ancient lush forest all the way down through the Oparara Basin, Look for whio (blue duck) in the whiskey-coloured streams and try to separate kea, kaka and kakariki from the cacophony of birdsong. Approximately halfway down the valley the Sunshine Flat offers a toilet, shelter and interpretation panels - an ideal place to stop for a snack. Continuing down the trail, there are several side trips on offer: take Adams Flat Track and Fenian Track to see discarded mine workings; a short way past the Fenian Track junction is the loop trail through Fenian Caves. This is a short but very exciting technical jaunt through three caves - a head torch is essential, and take care after heavy rain.
You will need to arrange to be picked up at the Fenian carpark, or resign yourself to a road run (approximately 7km) back into Karamea.

Eminently runnable, and a fine example of West Coast native forest. The Valley track was purposefully constructed to be "all weather"- I ran out & back from Fenian in an absolute deluge of rain and the drainage was impressive- really good for security of footing:)

Sensational! This is as close as you'll ever get to running with the moas. Definitely got to be in the top half dozen places I've ever explored

This was awesome... did it both ways, but only through the tunnel cave on the way up. A bit of everything... just about perfect!

Did this track in the 20km Oparara Wilderness Trail Run. Beautiful track with great views to keep you going!
