Warren Island Wilderness

Warren Island Wilderness is an 11,559-acre federally protected Wilderness Area in southeastern Alaska, managed by the Forest Service. The area offers remote backcountry experience in a landscape shaped by the region's maritime climate and temperate rainforest character. Visitors come primarily for backpacking and hiking in primitive, non-motorized terrain where solitude and self-reliance are central to the experience.

As a designated Wilderness, Warren Island operates under strict preservation rules: no roads, motorized vehicles, or mechanized travel are permitted. All visitors must practice Leave No Trace principles and be prepared for complete self-sufficiency. Access is by water only, and the area sees limited use due to its remote location and the logistics required to reach it. The Alaska summer season—roughly June through September—offers the most reliable conditions, though weather in southeastern Alaska can be unpredictable year-round. Visitors should be experienced in wilderness travel and equipped for wet, cool conditions.
