Apple Tree Bay Campsite sits on a sandbar at the mouth of Simonet Creek within Abel Tasman National Park, Nelson/Tasman region.

Accessible only by foot or boat along the Tinline to Anchorage section of the Abel Tasman Coast Track — one of New Zealand's Great Walks — the site offers a beachside setting framed by native bush.

Simonet Creek, which flows into the bay, serves as the campsite's drinking water source. The campsite has 15 non-powered tent sites and is managed by the Department of Conservation. Advance bookings are required.

The bay's name is believed to date from around 1928, when a family purchased land there, though French explorer Dumont d'Urville had earlier called it La Grande Plage during his 1827 coastal survey.
