Trout River offers two non-motorized boating routes. The first starts at the outflow from Muncho Lake. At this point there is a small bay that acts as a launch point to the upper portion of the river. This part is class 2 with small waves and some tight corners. It will take you about 6 hours to reach the pull-out found at the Trout River Bridge on the Alaska Highway at M=455, KM=733.
The other option is to start at the Trout River Bridge (M=455, KM=733) and go to where the Alaska Highway starts pulling away from the river. Do not travel past this as the river does drop over a waterfall a little further on. Be aware of a very large rock and hole at Prochniak Creek not much past the start of your trip. This portion of the river could be classified at 3 or 3+ depending on water level.
