Barnes Lake Hot Springs
Barnes Lake Hot Springs emerge at a modest 79 degrees Fahrenheit within the Tongass National Forest, maintaining temperatures just 38.1 degrees above ambient air in this remote corner of the City and Borough of Wrangell. The springs flow from federally protected forest lands managed for both extractive and conservation uses.
The springs emerge at 129 feet elevation from a landscape receiving over 132 inches of annual precipitation and 511 inches of snow, creating an extremely wet environment dominated by temperate rainforest. The spring water supports the thermal ecosystem at this low elevation near water, where ambient air averages just 40.9 degrees Fahrenheit. The backcountry location ensures dense forest surrounds the thermal feature.
Barnes Lake Hot Springs formed through regional geothermal processes beneath the temperate rainforest. The relatively modest temperature compared to other Southeast Alaska springs suggests limited depth of water circulation or cooler basement rock in this particular location.
Backcountry access only—nearly 20 miles from the nearest road through dense forest and challenging terrain. The Mount Flemer Cabin, 4.1 kilometers away by floatplane or boat access, provides base camp facilities. The Stikine River corridor offers water-based approach routes. Serious backcountry skills and careful planning are essential.
