Mingha - Deception Route

Suitable for well-equipped people with previous backcountry tramping experience. River crossing skills essential. The best seasons to tramp are summer, autumn and early winter.

Both the Deception and Mingha rivers can be dangerous. Do not attempt this trip when these rivers are high or when bad weather is forecast. Travel along the Deception River requires up to 30 compulsory river crossings. Rivers can flood at any time of year. If rivers and side streams are in flood, seek shelter and wait until water levels fall before crossing. The best route can vary, particularly in the Deception, after storms and heavy rain events. The safest river crossings may not be where the markers are. You must assess your river crossing and if it seems difficult, try looking for a better crossing point.

Hazards include flooded rivers, avalanches, steep drop-offs and bluffs. There are many challenging river crossings on this track, which become impassable when the rivers are high. Check the weather before you go and carry extra food for river/weather delays. See Tramping in Arthur's Pass National Park (PDF, 762K) and New Zealand's Land Safety Code. Before setting out, check the latest track conditions and avalanche advisory with the Arthur's Pass Visitor Centre.

If you plan to cross unbridged rivers or side streams, know how to cross safely and be prepared for if you cannot cross. Do not cross if the river or stream is flooded, you cannot find safe entry and exit points or are unsure it’s safe. Turn back or wait for the river to drop. If in doubt, stay out.
