Scalding water at tidewater. Bell Island Hot Springs, on the Tongass, comes out of the ground well past the point where skin can stand it. Ketchikan is the closest town, a bit over forty miles off, and there is no road connection to the spring itself. Public access is listed as open.

Location

The spring sits at sea level on Forest Service land. From where the nearest road ends it is a walk of about four and a half miles. This corner of Southeast Alaska stays wet most of the year, with rainfall above a hundred inches, and the climate record shows a large snow figure too. Blind Pass Cabin, a Forest Service cabin, is about as far away as the road is.

The record flags December through February as the best months, which in this climate means short days and rain with snow mixed in. Dress for a wet hike. The water was measured hot enough to burn, so stay away from the source and look for where it has cooled, testing before you touch it. Chemistry on file dates from a 1976 sample and may have drifted since.

History of Bell Island Hot Springs

The USGS has Bell Island on its books as a sampling site. The water sample, taken in July 1976, came back mildly alkaline with a moderate load of dissolved solids.

Terrain
