The Abel Tasman Coast Track is one of New Zealand's nine Great Walks — a 60km trail of golden-sand beaches, granite headlands, and native bush running along the edge of the national park. It is usually walked over three to five days, with DOC huts and private lodges spaced along the route, but it is also possible to do day sections using water taxis from Kaiteriteri or Marahau to drop you at a trailhead and collect you at the other end.
The track is justifiably popular, which means the main beaches get busy in January and February. Book huts well ahead for summer trips. Off-season walking — April to October — is quieter, the light is often better, and the forest birds are more active. Sea kayaking is an excellent alternative to walking: the coastline shows differently from the water, and fur seals, dolphins, and penguins are regular sightings.
