Totara Flat Campsite is a campground listed at 1766 Kauaeranga Valley Rd, under Totara Park in Manukau City, Auckland, with a 4.4 Google rating.
Basic campsites reward a bit of preparation. Check whether the site has toilets, drinking water and cooking facilities, and plan to bring what is missing, including food, a stove, rubbish bags and warm bedding. Find out whether bookings are needed and what the rules are on fires, noise and pets. Cell coverage can be poor in valley settings, so download directions and tell someone where you are going. Regulars arrive in daylight, pitch away from rivers and low ground that can flood and pack for cold nights even in summer.
The Kauaeranga Valley Rd address is more usually linked with the Coromandel than south Auckland, so check the exact location before you set out.
