Dog Stream Waterfall is a tourist attraction on Clarence Valley Road in Barrington, Christchurch, holding a 4.6 rating from 80 Google reviews, and described by an online guide as a hidden gem in Hanmer Springs. With waterfalls, timing is everything. Flow rises and falls with the weather, so a fall that thunders after decent rain can dwindle to a trickle in a dry Canterbury summer, and it pays to check conditions before committing to the walk. Tracks to falls are often rougher than the destination suggests, with mud, roots and stream crossings that call for sturdy shoes and extra time. Locals tend to set out early, beating both the crowds and the afternoon heat. For anyone making the trip out along Clarence Valley Road, Dog Stream Waterfall is the kind of well-reviewed spot that repays the drive.
