Ten geothermal springs come up next to the small settlement of Baranof Warm Springs, on the eastern side of Baranof Island and about twenty miles from Sitka. The water arrives too hot for a straight soak, and it is strongly alkaline. Tongass National Forest wraps the community. Nothing says who holds the ground beneath the springs, and public access has not been recorded either.

Location

There is no road to Baranof Island and no air service. You get there by boat. Something called Old Mine Road is the nearest road the record can find, twelve miles distant, which tells you how far this is from anywhere drivable. The settlement sits almost at sea level on a wet coast where winter snow stacks up deep and rain falls most of the year. Baranof Lake cabin is two and a half miles away.

January through March rate highest for a visit. The water was sampled once, in 1972, and came out hot enough to need care, so test it before committing. Sort out a boat before anything else. No fee is noted, and the cabin at Baranof Lake is the nearest place to stay that the record knows about.

History of Baranof Warm Springs

Wikipedia describes the site as a series of ten geothermal mineral springs inside a small seasonal community that shares their name, with Tongass National Forest on every side and no way in except by water. The USGS sampled the water in March 1972.
