Outing Highlights

THE RIVER

Five hours and 40 kilometres on mellow rapids

This trip covers about 40 km of the Waimakariri with around five hours spent on the river; the grade 1–2 rapids make the run approachable and well suited to families and first‑time rafters.

THE ROUTE

From Arthurs Pass headwaters to Woodstock

The run follows the Waimakariri from the glacial mountains of Arthurs Pass and finishes at Woodstock, retracing the same river corridor used in the coast‑to‑coast river leg.

THE RIVER’S CHARACTER

A Canterbury classic: cold, rushing water with local meaning

The Waimakariri is one of Canterbury’s largest and most loved rivers; its Māori name is translated as ‘river of cold rushing water’, a reminder of the glacier‑fed source and brisk flow.

What the day feels like

How the day unfolds

The outing is framed as a single, full day: an early start in the Arthurs Pass area leads to a river launch at Gooseberry Stream and a gradual, scenic drift that concludes at Woodstock. The river’s gentle grade and long float make for steady downstream travel punctuated by broad valley scenery and family‑friendly whitewater.
