Where You'll Be

Native beech forest on the Upper Grey / Māwheranui

The Upper Grey / Māwheranui runs through remote West Coast backcountry near Reefton and Greymouth - country you can only reach from the river. Over two days you'll paddle entertaining rapids, drift through native beech forest, camp on the riverbank, and finish through the breathtaking Gentle Annie Gorge. It suits anyone comfortable with a full, active day outdoors and keen for a night under canvas - first-timers included.

The Experience

With beech trees crowding right down to the water, you know you're on the West Coast from the first paddle stroke. Over two days you'll run entertaining Grade 2–3 rapids, drift through steep-walled gorges, camp beside the river, and finish through the breathtaking Gentle Annie Gorge - country most people never see, because the only way in is by river.

Day by Day

Two days on the water, a night camped on the riverbank - here's how the journey unfolds. Open a day for the full run-down.

Day One - Onto the River

We start at 9am in Reefton and drive about an hour to the river. Stow your camp clothes in dry bags, pull on the river gear we provide, and after a full safety briefing we're away - no experience needed, the guides teach you everything first. The opening stretch is all rocks to read and manoeuvre around, with beech forest right down to the water for the first few kilometres. Before lunch we push through some fun rapids including the Log Jam, then the valley opens out to easy Grade 2 water - look back upstream for a cracking view of Mt Rameses, towering 1,453m above the river. Late afternoon we make camp on the river's edge: dinner over the open fire and a few laughs before bed.

Highlights: Beech-lined Narrows · The Log Jam · Wide-valley Grade 2 · Mt Rameses (1,453m)

Day Two - The Gorges

After a hearty breakfast the river really comes alive. The hills tighten in for the rock-garden section, the slopes around you a magical mix of moss, beech and fern. We float past the tall waterfall we've nicknamed the Lady of the Grey, then meet the biggest water of the trip - Double Rock and Annie's Waves, a wave-chain that rolls us along like a gentle roller coaster to lunch. The finish is the showpiece: the Gentle Annie Gorge, a steep-walled canyon reachable only by river - and then a second gorge, just as stunning. On a hot day they're perfect for a swim and a float through the deep pools. We're back in Reefton around 4pm.

Highlights: Rock-Garden Section · Lady of the Grey · Double Rock · Annie's Waves · Twin Gentle Annie Gorges
