The route starts on SH73 near Klondyke Corner, about 10 km east of Arthur’s Pass village. It follows O’Malley’s Track past Anti Crow Hut, then crosses open river flats and beech forest before reaching Carrington. Expect several unbridged channels and changing river conditions; river-crossing skill is essential. Avoid the route during or after heavy rain, check DOC’s latest access advice, and be ready to turn back. Carry spare food in case high water delays your return. Dogs are not allowed. Avalanche risk affects day trips above the hut, usually from May through November, though snow can bring danger outside that period.
