From its intersection with SH4 north of Wanganui, the Whanganui River Road runs for 80 km through the lower river valley to Pipiriki amid some of the most rugged, majestic scenery in New Zealand. The River Road follows native forest clad hills and farmland, and beautiful valleys of the Whanganui National Park. From Pipiriki, the road continues for a further 40 km to emerge at Raetihi and rejoin SH4.

The River Road provides access to the Whanganui National Park, canoeing and jet-boating. There are many walking and tramping opportunities. It provides visitors with an intimate and adventurous journey, through scenery dreams are made of, and communities whose traditional values have long been forgotten by modern society. Here a traffic jam means a family of piglets crossing the road; rush hour is three vehicles within 30 minutes. The only delays are caused by people stopping to chat, or sheep moving to better grazing.

Although this backcountry byway is being gradually upgraded to a sealed surface for its entire distance, many sections remain narrow and windy, and travellers should allow plenty of time to safely complete their journey, and enjoy the natural beauty and historic features of the area.

A separate brochure includes details of local people who offer accommodation, and adventuresightseeing opportunities. Many of these people are involved with day to day farming activities, so be sure to make advance contact.

Permission must always be obtained before entering private property, which includes the many local marae.
