Tin Boat Reserve is a park in Onetangi, on Waiheke Island, with a strong 4.8 rating on Google. A good reserve does a few simple things well: open grass, honest shade, a seat that catches the view, and enough room that a kickabout doesn't collide with someone's picnic. The details tell you more than any photo — whether the grass has been mown lately, whether the shade lasts past mid-morning, and whether there's a tap or table worth planning a visit around. On an island, practicality counts: bring what you need, take rubbish home, and check the signage for dog rules, as off-lead access varies from reserve to reserve. Locals tend to arrive early or late, when day-trippers thin out and the low light does the scenery's work for it. For a picnic or a slow afternoon in Onetangi, this is one of Waiheke's dependable patches of green.
