About Pine Valley Waterfall

Pine Valley Waterfall sits at the beginning of the Pine Valley Track in Mount Richmond Forest Park. The 10-metre drop and downstream cascades form where the Pine Valley Stream cuts through bouldery beds in mature regenerating native forest. The short walk from the carpark provides an easy introduction to the park without requiring a full backcountry tramp.

The Pine Valley / Mill Flat area has a history of early 20th-century logging, with evidence of former mill sites still visible in the landscape. The valley has since regenerated into lowland bush featuring mixed beech and podocarp species, supporting native birds such as kererū, tūī, korimako and piwakawaka. The site also serves educational groups studying freshwater and forest ecosystems.

Access starts from Pine Valley Road off Northbank Road. Visitors reach a carpark before the stream ford, with a short walk to the swing bridge and recreation area. The waterfall itself is reached quickly along the initial section of the Pine Valley Track through native forest.

Other Walks in the Area

The Pine Valley / Mill Flat area offers several walking options of varying difficulty. The Mill Flat Walk is a 10-minute easy loop track suitable for casual walkers and families. The waterfall walk provides a short, accessible option on a natural surface. The Mt Fishtail track is the more demanding route, taking 5 hours one way from the Pine Valley Hut site area and requiring experience, fitness and proper preparation for backcountry conditions.

Wasp Warning and Other Hazards

Wasps are common in the reserve, with numbers that can be high from January to April. DOC advises carrying antihistamine if allergic. The stream is reasonably fast-flowing and bouldery, becoming slippery and prone to flooding in heavy rain. Do not attempt crossings in flood conditions. Tracks have uneven surfaces, so sturdy footwear is recommended. Water in the park may not be safe to drink without treatment.
