Tramps around Punakaiki include the Truman Track (30 minutes return) and the Punakaiki–Porari Loop (3½ hours), which goes up the spectacular limestone Pororari River gorge before popping over a hill and coming down the bouldery Punakaiki River to rejoin the highway.
Surefooted types can embark on the Fox River Cave Walk (three hours return), 12km north of Punakaiki and open to amateur explorers. BYO torch and sturdy shoes.
The Paparoa National Park Visitor Centre has free maps detailing other tramps in the area. Note that many of Paparoa's inland walks are susceptible to river flooding so it is vital that you obtain updates from the centre before you depart, and always heed warning signs and roped-off trails.
