Five Rugged Routes That Put River Safety Skills to the Test
Many tramps across the motu involve crossing unbridged streams or rivers, making river safety one of the most important skills in your tool kit. Rivers can quickly become unsafe from rain or snowmelt, particularly in spring. So, as well as knowing how to cross, river safety involves knowing the signs of an unsafe river and being prepared to wait it out. MSC’s Plan My Walk Content Advisor Anna Thomson shares five adventurous trips where river safety skills are essential.
Mingha-Deception Route | Arthur's Pass
Used for the mountain run section of the annual adventure race Coast to Coast, this demanding 2-3 day, expert grade, one-way track, follows the Deception River up to Goat Pass and down the Mingha River (or vice versa). There are two huts enroute and one bivvy.
The Deception River must be crossed more than 30 times during the ascent or descent from Goat Pass, and several river crossing fatalities have occurred here over the years. The narrow gorge means that water levels can rise quickly, and there are many cascades and boulders to navigate along the largely unformed marked route. This means strong river crossing skills are essential and the route should not be attempted in bad weather.
Back Ridge Loop | Hawke's Bay
A challenging 3-4 day tramp through native beech forest and along the open tops of the Kaweka Range, this loop offers fantastic views over Hawkes Bay. Expect steep terrain and exposed ridgelines that are often subject to gale-force winds and sudden changes in weather conditions. There are four standard huts and one bivvy along the route.
The section from Kiwi Saddle Hut to Kiwi Mouth Hut involves numerous crossings of Kiwi Creek, although there is an alternate track if the creek is in flood, which is steep and arduous. You will also need to cross the unbridged Tūtaekurī River either at the beginning of your trip or on your return to the car park, and in heavy rain it may not be possible to cross. Carry an emergency shelter, an extra meal and an emergency communication device in case you need to wait for the water level to drop.

Kapakapanui Loop | Wellington/Kāpiti
Climb the isolated Kapakapanui Peak (1102m) situated in the southwest corner of the rugged Tararua Range. It’s a 7-9 hour day loop or an overnighter if staying in the six-bunk Kapakapanui Hut, which is located about a third of the way round going clockwise and does not require bookings. Be prepared for both a steep ascent and descent with rewarding views of the rest of the range and the Kāpiti coastline from the summit.
There are multiple unbridged crossings of the Ngatiawa River at the start of the track and some further stream crossings if you choose to continue the loop clockwise. Check the forecast before you go and postpone your trip if rain is forecast.
Travers-Sabine Circuit | Nelson Lakes
One of the most accessible and scenic multi-day circuits lies in the heart of Nelson Lakes National Park. Taking 4-7 days it showcases rugged mountains and lush valleys with an optional side trip to Rotomairewhenua, thought to be one of the clearest lakes in the world. There are six serviced huts along the route, all require booking in advance.
The loop follows the Upper Travers Valley, climbing up over Poukirikiri /Travers Saddle, and following the Sabine River to the shoreline of Lake Rototoa, before skirting the base of Robert Ridge back to Lake Rotoiti. Although the larger streams are bridged, there are several unbridged side streams to cross over the days that can quickly become swollen during or after heavy rain. Always carry an emergency locat or beacon with you and a two-way communications device so you can let someone know if you get delayed. The track also has more than 20 recognised avalanche paths, check the NZAA website before heading out in winter and spring.
Dusky Track | Fiordland
Traversing two mountain ranges and three major valleys, the 84km, 8-10 day Dusky Track is a slice of adventure for experienced and well-equipped hikers. Taking on this expedition requires arranging a boat service from both the Lake Hauroko end and the Lake Manapouri end. There are eight standard huts along the track, including a side detour to Supper Cove Hut, all of which are first come, first served.
Fiordland experiences high rainfall at all times of the year. Although there are 21 three-wire bridges along the track, these can become impassable during and after heavy rain. There are also unbridged streams and creeks to navigate, and sections of the track that can become flooded. River crossing skills are essential, as is taking an emergency shelter, extra food and an emergency communication device. Remember, if in doubt, stay out.
