Abel Tasman National Park is a national park located at the north end of the South Island of New Zealand. The park was founded in 1942, largely through the efforts of ornithologist and author Perrine Moncrieff to have land reserved for the purpose. With a coverage of only 225.3 sq km, is the smallest of New Zealand's national parks. The park consists of forested, hilly country to the north of the valleys of the Takaka and Riwaka Rivers, and is bounded to the north by the waters of Golden Bay and Tasman Bay. It is named after Abel Tasman, who in 1642 became the first European explorer to sight New Zealand.
Abel Tasman National Park does not extend beyond Mean High Water Mark on the adjacent coast. Between Mean High Water and Mean Low Water Springs, the beaches are gazetted as a Scenic Reserve, covering 7.74 square km in total. The Tonga Island Marine Reserve adjoins part of the park.The Abel Tasman Coast Track is a popular tramping track which follows the coastline; while an inland route, the Abel Tasman Inland Track, is less frequented. Kayaking, camping and sightseeing are other activities carried out in the park.
