Western Alaska consists of the coastal areas bordering Bristol Bay and the Bering Sea. Rivers flow westerly from the aged Kilbuck and Kuskokwim Mountains, through forests and lowland deltas and offer the most extraordinary fly fishing float trips in Alaska. The Yukon/Kuskokwim Delta is an aquatic system of immense proportions. The resident species abound in numbers, nourished by nutriments provided by healthy runs of all five species of Pacific salmon. Frontier River Guides offers Alaska fly fishing raft expeditions on the Aniak, Arolik, Goodnews, Kisaralik and Kwethluk rivers. We access these waters from Bethel, Alaska.
