Cascade Kauri is a forest park on Falls Rd in Waitākere, at the edge of the Waitākere Ranges west of Auckland and managed by Auckland Council. Google reviewers rate it 4.9 from 131 reviews, praising well-formed tracks beneath mature kauri and a popular walk out to the dam.
Kauri bush walking rewards a little planning. Tracks in these ranges are often steeper than the map suggests, with long flights of stairs, so match the loop to the legs you have: a stream-and-valley circuit for families, a full ridge trail if you want a workout. Boardwalks and shoe-cleaning stations exist for a reason — kauri dieback disease travels in soil on boots — so scrub and spray at every station and stay on the path. After rain, expect mud.
On Auckland's western doorstep, Cascade Kauri packs a dam walk, loops and shaded kauri into an easy half-day out.
