Lester Hot Springs is inside the City of Tacoma's watershed in King County, Washington, and access is listed as restricted. That is the fact that matters. The water reading on file is hot, above comfortable soaking temperature at the source. Riverbend is the town the record puts closest, around twenty miles away.

Location

Only about five hundred feet from a road, by the record, though that road has no name in the record and the land is municipal watershed property with a local conservation designation. Low elevation, Cascade foothills, wet climate, and snow that piles up in winter. The record marks access as restricted.

Do not plan a soak here without confirming permission with the City of Tacoma, since the watershed is marked restricted in the record. The Dalles Campground, about nine miles away, is where the record says to camp. Winter shows up as the best time on file. It is hot enough to hurt if you reached it. Test before touching.

Heat Below
89 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 30% 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.
