The Rakaia Gorge Walkway is an easygoing walk along a scenic section of the Rakaia River, with views of the river from various spots, and out over the Mt Hutt Range. It is suitable for families and those without tramping experience, although it can get a bit muddy. On a clear day the Rakaia River is a pleasing turquoise colour, and there are patches of native bush with exotics along the way.
The walk takes around 3 hours at a steady pace, and is on an obvious track the whole way. The best of two lookouts is at the furthest point on the route. You can return the same way from there, or continue on a short circuit. It’s mostly flat but can get quite muddy. There’s more information on the DOC website.
