Very Hot Source, Use Extreme Caution

At 160°F, the source water at Belknap Springs is hot enough to cause burns. Some hot springs this hot have cooler side pools or downstream areas suitable for soaking. Always test the water temperature before entering.

Belknap Springs is a private hot springs resort, and also the name of the small unincorporated community around it, near the McKenzie River. The record files it under Deschutes County with Sisters as the nearest town, twenty-five miles or thereabouts. Wikipedia puts it in Lane County. The source water is scalding, far too hot to touch, and whatever soaking happens here is under the resort's control. Public access: nothing recorded.

Location

Five hundred feet or so from North Belknap Springs Road, low in the river valley. The climate is wet, well over sixty inches a year, with heavy winter snow for such a low elevation. Limberlost Campground is listed a little over a mile away.

Since this is a private resort, expect to pay and to use their pools on their terms, though no fee amount is recorded. Do not approach the source. The winter months show as best on file. Water chemistry, including iron alongside calcium, magnesium, sodium, sulfate and chloride, was last sampled in 1981, so the mineral figures are old.

Heat Below
91 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 33% 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.
