Rothesay Bay Grass Airstrip is listed as a historic site at Rothesay Bay, on Auckland's North Shore. It has a 4.1 rating on Google. The directory gives no further detail, so it is worth looking up the site's history before you go.
A good historic site helps you understand a place through what remains on the ground, often with signs or plaques to give context. Sites connected to early aviation or local history are usually quick to visit, so they suit a short stop or a gentle walk, and the open space and views are often part of the appeal. Before you go, read what you can about the site, as background makes a visit far richer, and check where to park and whether the ground is open to the public. Regulars know that mornings and weekday afternoons are quietest, that grass can be wet and slippery after rain and that the harbour wind can be cool even on a sunny day. Stay on public paths, keep dogs under control where rules apply and take your rubbish home.
For anyone exploring Rothesay Bay and the North Shore coast, this airstrip is a local landmark worth researching before you visit.
