Jul 30, 2016. More Yukon canoe adventures: 355 km of paddling the Big Salmon and Yukon River. We wanted a challenge, we got a challenge. Log jams, portages, wild water II and adverse weather – the Big Salmon had it all. But also great fishing, beautiful mountain scenery and some gold rush history. Spotted our first timberwolf, beaver, more porcupine and heaps of squirrels.
