Bagby Hot Springs sits on the Mt. Hood National Forest, filed under Linn County, with Mill City about twenty miles away as the nearest town. The water comes out hot, hotter than you would want to sit in straight, in the range where it needs cooling before a soak. The Forest Service lists access as open.

Location

From Forest Road 70 it is a walk of about three quarters of a mile. Wikipedia describes heavily forested Cascade country. This is one of the wetter places on the list, close to eighty inches of precipitation, and the winters still bring a lot of snow despite the modest elevation. Kingfisher campground is the nearest one on file, around five miles away.

The record's best months are the dead of winter, which with this snowfall means checking whether Forest Road 70 is drivable before you commit. At source the water is hot enough to hurt, so test it before you get in. Camping at Kingfisher is the nearest option listed. No fee is recorded.

History of Bagby Hot Springs

Wikipedia places the springs about 67 miles southeast of Portland and 98 miles east of Salem, in the Cascade Mountains, a little outside the boundary of the Bull of the Woods Wilderness. The USGS carries the site in its thermal spring inventory.

Terrain

Heat Below
81 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 17% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
