Perth River

The Perth River is a river located in the Southern Alps in the West Coast region of New Zealand's South Island. Its source is in terrace icefields north of the Rangitata Divide and is joined by multiple tributaries, including a creek from Abel Lake. It features a number of rapids and passes through two gorges before meeting the Whataroa River. The river is largely inaccessible, but recently, an adventure tourism company has begun offering "heli-rafting" on the river: whitewater rafters are flown in by helicopter to raft the river.

Kayakers have been flying ("heli-boating") up the Perth for a number of years. The normal rafting put in at Five-Finger stream gives a nice class III-IV run with one amazing gorge. By flying up to Scone Hut, the trip becomes one of the best IV-V runs on the coast. More recently paddlers have been flying or walking upstream of scone hut for some V-V+ excitement.
