Styx Mill Conservation Reserve is a large council-run reserve at 130 Hussey Rd in Northwood, Christchurch, following the Pūharakekenui/Styx River corridor. It has a 4.5 rating from 603 Google reviews. Its website says there are entrances off Styx Mill Road and Husseys Road with plenty of parking, public toilets near the Husseys Road car park, and strict dog rules to protect wildlife, with leashed dogs allowed on set paths and off-leash dogs only in the fenced dog park. It describes wetlands that were important for food gathering by local Māori. Reviewers mention bird life, a lake, native bush, a dog park and quiet walking tracks.
A conservation reserve exists to protect habitat, so the best visit is a quiet one: stay on tracks, keep dogs where permitted, take rubbish home and keep noise down. Bird watching is best early in the morning, and binoculars help. Wear sturdy shoes, as wetland paths can be damp, and check the weather. Signs show which entrance and walks suit your time. Weekends are busiest around the dog park, so weekdays are calmer.
For a quiet nature walk and birdlife within Christchurch, Styx Mill Reserve is a rewarding place to visit.
