Cox's Bay Reserve Walking Track is a walking track in the reserve at Patumahoe, in Franklin south of Auckland, and holds a 3.0 rating on Google.
Reserve tracks are often informal affairs — grass or dirt paths worn along paddock margins and bush edges rather than built walkways — so conditions move with the weather. After a wet winter, low-lying sections can hold water and turn slick, while in high summer the same ground bakes hard and dusty. Shoes with grip beat smooth soles, and a quick look at recent reviews or the council's parks page will flag mud or closures before you set out. Locals tend to walk early before the day heats up, and keep dogs on a lead where farmland borders the reserve.
For Patumahoe residents after a short, unfussy leg-stretch without leaving the village, it's a handy option.
