Hi There Please find a description of the walk below - we suggest you need average to good fitness levels - you need to know you can walk for 3 hour with some up & down-hill sections. The walk starts at 600 meters (2000 feet) above sea level where you start off with a stroll across the Siberia Flats and across the Siberia Stream. This section will be accompanied by your pilot, listen carefully as the pilot will give you a verbal description of the walk and stream crossing. This section is about 300 meters (328 yards) long and is in open tussock land. You cross the Siberia Stream under supervision of your pilot remembering in general the wider the stream the shallower the water. The stream is generally between ankle and half way to the knee in depth and quite brisk in temperature – a unique part of this true New Zealand wilderness experience. Stream crossings are a common practice in New Zealand when we go tramping. (kiwi slang for hiking or trekking). Once across the Siberia Stream follow the well-worn track marked with ORANGE TRIANGLES, walk down the Siberia Valley for about another 700 meters (765 yards) before entering the native Silver Beech Forest, it is then a steady climb to the highest point on the track at 730 meters (2,395 feet) above sea level and about 130 vertical meters above the Siberia Valley floor this section of the track is about 2km (2100 yards) long and is about the halfway point. From the highest point it is about 2 KM (2100 yards) of descending to the Wilkin River valley floor at 300 meters (984 feet) above sea level . Once on the Wilkin River valley floor it is about 1.1 KM (1,200 yards) downstream to the Jet Boat pickup point sign. If you would like any other information please let us know.
