Kumara storage pits is a historic site at 379A Gordons Rd, on Waiheke Island, with a Google rating of 5.0.
A good historic site is easy to find, free or low-cost to visit and worth a few quiet minutes. Kūmara storage pits, known as rua kūmara, are traditional Māori food stores, dug into the ground to keep kūmara through winter, and they can still be seen as shallow hollows on many headlands and hillsides. They are sites of cultural and archaeological importance, so look but do not dig, climb into them or disturb the ground, and read any signs. Take care around uneven ground and cliffs, wear sturdy shoes and bring sun protection and water, as many such sites are exposed. Regulars read about the history beforehand so the visit means more, and they treat the site with respect. Waiheke is reached by ferry, so check sailing times.
For visitors to Waiheke Island, the Kumara storage pits on Gordons Road are a short stop that shows the island's early history.
