This river has a major State Highway running alongside the river for most of its navigable length, with access points at many places. Depending on what difficulty you can manage, the river, after rain, offers a spectrum of trips from Grade 2 to 5. Basically the further up you get in - the harder the trip. You can scout quite a bit from the road.
Grade 2 – put in at the Inangahua Swingbridge Reserve on the right about 8 km from Reefton, and paddle down to Reefton.
Grade 2 rapids
Grade 3 – put in 10 km above the Swingbridge and paddle down to the Swingbridge.
Grade 3+ – put in 14.3km above the Swingbridge
Grade 4 – put in a Tobin's Bridge 18.3 km
Grade 5+ – put 21 km above the Swingbridge, and carry a chainsaw.
Hazards – trees fall in the river and wash down. In some places these trees are a mandatory portage.
Flow – the river is best during or after rain. A good river to use when others have to much water.
Upper Grey River
The Upper Grey is accessed via Palmers Road. The turn off is on a big hairpin bend near Springs Junction. The best put in is directly into the Blue Grey River at the bridge. This gives you a sweet scenic run of Grade 2 with some rapids Grade 3. Exit at the creek prior to the locked gate at this rapid in the photo below.
