BLM Wild & Scenic River · ADF&G Trophy Grayling Water

Alaska’s only road-accessible Wild & Scenic River and one of the most popular float-fishing trips in the state. The Gulkana drains Summit Lake and flows 81 miles to join the Copper River, offering a classic 4-5 day float with excellent king salmon fishing in June, grayling all summer, and red salmon in the tributaries. The Main Branch is BLM Wild & Scenic, and the river passes through remote spruce taiga and gravel-bar country with abundant moose and the occasional brown bear. Put in at Paxson Lake; take out at Sourdough Creek or Gulkana.
