ADF&G names the Thorne River one of the best road-accessible steelhead streams on the island, with spring and fall runs. Fall coho arrive in late August and peak in September, and cutthroat and rainbow trout are in the river year-round. The Gravelly Creek day-use area, 3 miles west of Thorne Bay, has a shelter, outhouses and a short accessible trail to the water.
