Abel Tasman National Park is in the Nelson Bays region of the South Island of New Zealand, between Golden Bay and Tasman Bay. Located in the Tasman District on the northern tip of the South Island. The park is closed to vehicles, and access is either on foot (from one of the various carparks mentioned below) or by boat, or if you've got money to spend it is possible to charter a helicopter or small plane (Awaroa only).
Some of the land in the park is privately owned - mainly in Awaroa Bay and Torrent Bay. It is important to remember this when visiting the park - the locals are friendly but they don't want loads of travellers walking through their backyards all the time! However these areas are clearly marked so you shouldn't have any problems.
The most notable feature of the park are its beaches. The golden sands bring many visitors, some for just a day, others for overnight trips. However, moving away from the beaches and inland, the park is mountainous and rough.
