Wairere Boulders Nature Park

At Wairere, massive basalt rock formations have been eroded into odd fluted shapes by the acidity of ancient kauri forests. Allow 40 minutes for the main loop track; expect a few dips and climbs. An additional track leads through rainforest to a platform at the end of the boulder valley (1½ hours). The park is signposted from SH1 and Horeke; the last 3km are unsealed.
