Why go: The Southland approach to the Routeburn Track is a masterclass in contrast — from moss-dripped beech forest and sheltered river valleys to open alpine saddles and panoramic summits. For travellers seeking a classic New Zealand Great Walk with big skies, sculpted ridgelines and intimate high-country wetlands, this side of the route delivers consistently dramatic scenery, day after day.
The highlights: Step out from the lower forest into the boardwalked realm of Key Summit, one of the track’s signature highlights. Here, a short, well-formed loop crosses peatland and tussock, rewarding modest effort with wide, cinematic views over tarns and mountain shoulders. Further along, Lake Howden appears like a polished mirror tucked in a high valley — a calm, reflective foil to the rugged peaks that frame the track.
Landscape and atmosphere: The Southland section feels distinctly alpine. In the lower reaches, silver beech and ferns create a cool, cathedral-like corridor; breezier, open country replaces the canopy as the track gains elevation, exposing the sculpted forms of ridges, cols and hanging valleys. Seasons paint the route in different palettes: the vivid greens of spring, blossom and wildflower flush through summer, and autumn’s burnished golds and ambers bring the forest to life.
Pace and planning: The Routeburn is best experienced at an unhurried pace that allows time for summit sidetrips, photography and quiet mornings by tarns. Whether you turn Key Summit into a standout day walk or incorporate it as part of a multi-day traverse, build flexibility into your itinerary — weather and personal
