The trip to Welcome Flat Hut along the Copland Track is a bucket list walk for any Kiwi tramper: it’s a quintessential South Westland valley, with natural thermal pools by the hut.
Yes, flooding and landslide risks can bring about track closures. It’s the crossing of Rough Creek, near the start of the walk that can cause problems. There is a bridge, but that requires a 45-minute detour so people risk the crossing, according to DOC. There’s also an active landslide further up valley that heavy rain could trigger so, after a certain level of rainfall, DOC simply locks the entrance gate. Otherwise, all gnarly stream crossings are bridged and a new bridge over McPhee Stream is expected to be completed for this summer. So, check the weather forecast before you go.
At first, the walk meanders up the wider Karangarua Valley. Look for chamois grazing on the river flats. Some sections follow an easy, former pack trail. These are remnants from the early 1900s when the Department of Tourist and Health Resorts started the development of a West Coast to The Hermitage walking and climbing route to encourage tourism.
Obviously no campervans in those days.
The landscape changes as the track turns into the steeper Copland. From here, the river’s milky-hued glacial torrent pounds over giant, shiny schist rocks on its way to join the slower-flowing Karangarua River. In parts, there’s some easy boulder-hopping alongside the river.
Blanketing the valley sides, all the way to the upper rocky bastions of the Sierra and Copland Ranges, is southern rata forest. Underfoot, and as the track steadily gains altitude, the forest is tangled and varied; mixed broadleaf and podocarps giving way to fuchsia, dracophyllum, olearia and kaikawaka.
