Andreafsky Wilderness, Protected wilderness area in Alaska, United States.
Andreafsky Wilderness is a protected area in Alaska's Yukon Delta, characterized by flat wetland tundra that transitions to higher ground in the south, with the Andreafsky River and East Fork running roughly parallel. Together these waterways form the dominant features of the landscape.
This area became federally protected in 1980 as part of the Alaska National Interest Lands Conservation Act, which established it within the Yukon Delta National Wildlife Refuge. The legislation reflected growing concern for preserving Alaska's natural ecosystems.
Yup'ik communities in nearby settlements depend on the rivers for salmon fishing, a practice that has shaped life in the region for generations. The waterways remain central to local food sources and seasonal rhythms.
Reaching this wilderness requires flying to Bethel Airport and then arranging water or helicopter transport, as no roads lead to the area. Weather conditions can be unpredictable and facilities within the refuge are minimal.
Two of the world's only known breeding sites for Bristle-thighed Curlews are located here, and these rare birds undertake one of the longest uninterrupted migrations of any bird species. Each year they depart for the Pacific islands and return to nest in the same locations.
