Okarito is a tiny coastal settlement north of Franz Josef, reached by a side road through rainforest from State Highway 6. It is one of those West Coast places that feels almost deliberately quiet: a handful of houses, a beach, a lagoon, and the Southern Alps rising behind the bush when the cloud lifts.
The reason to come is the wetland. Okarito Lagoon is New Zealand's largest unmodified coastal lagoon, a tidal maze of open water, mudflats, and forest edge where white herons feed and the rare rowi kiwi survives in the surrounding sanctuary. Kayaking is the classic daytime trip; guided kiwi walks run after dark when conditions are right.
The village itself is barely a village, which is part of the appeal. Visit Donovan's Store, climb the Okarito Trig Walk for a view over lagoon, sea, and mountains, then walk the beach until the Tasman weather tells you to turn back.
