The Lower Ruamahanga Track to Cow Creek Hut, via Cow Saddle is a rugged route in the Tararua Forest Park that follows the lower Ruamahanga River, climbs over Cow Saddle and descends to Cow Creek Hut, a DOC hut. It starts near the end of Ruamahanga Gorge Road, off State Highway 2 near Mt Bruce, about 46 km from Palmerston North.
DOC grades it as an Advanced tramping track and Expert route, and times it at 5 hours from Ruamahanga Gorge Road to the hut. There are many unbridged stream crossings, so the trip depends on river levels and good backcountry judgement.

About Lower Ruamahanga Track to Cow Creek Hut, via Cow Saddle
This route takes a different line into the Tararua Range from the Wairarapa side. Rather than climbing a ridge from the road, it starts low and follows the Ruamahanga River upstream along its true right, all the way to Cleft Creek.
At Cleft Creek the route leaves the river and heads up and over Cow Saddle, then descends the other side to a swing bridge close to Cow Creek Hut. Along the way there are many unbridged stream crossings. DOC asks trampers to assess each one carefully, and if in doubt, stay out.
DOC describes the ground as a typical Tararua backcountry route: rough, uneven, muddy and slippery, with scrambling over tree roots. The Expert route grade reflects that, so this trip suits experienced trampers with river crossing and route-finding skills rather than people new to the park.
From Cow Saddle there is an optional side trip on a track that climbs to the 1130 m spot height, worth considering if the weather is clear and you have time in hand.
Cow Creek Hut
Cow Creek Hut is a DOC hut, reached at the end of this route by a swing bridge. DOC’s route page doesn’t give hut facilities, bunks or booking details, so check the Cow Creek Hut page on the DOC website before you go.
River Crossings and What to Carry
With so many unbridged streams, the weather in the days before your trip matters as much as on the day. Know how to cross rivers before you go, and if a river or stream is flooded, or you can’t find clear entry and exit points, turn back or wait for it to drop. DOC suggests checking NIWA river flow forecasts.
The Tararua Forest Park is known for wild, fast-changing and unpredictable weather, so pack warm and waterproof clothing even if the forecast is good. DOC recommends carrying a torch, spare food and a distress beacon. Plan My Walk helps bring the forecast and gear list together, and you should leave your intentions with a trusted contact.
