Pukeatua Reserve Trig Hill is a park at 144 Trig Hill Rd in Onetangi, on Waiheke Island, and carries a 4.6 Google rating. Reserves that take their name from a trig station usually sit on a surveyed high point, which is why they tend to be hilltops of open grass with wide outlooks. Expect mown slopes and tracks rather than built facilities — playgrounds, toilets and kiosks are never guaranteed — so wear decent shoes and carry water. Exposed ground makes weather matter: early morning and evening bring the best light, and a calm day at the beach can be a breezy one up top. If it is a view or a quiet patch of grass you are after, a reserve like this is the pick; for shade and picnics, a flat, tree-lined park serves better. For a taste of Waiheke's high country without leaving Onetangi, this well-rated reserve is a natural stop.
