## About Warm Spring

Warm Spring is a small thermal spring in the Angeles National Forest, Los Angeles County, about nine miles out of Castaic. The water comes up around bath temperature, warm enough to sit in on a cool morning. Public access is open on the record and the Forest Service holds the land. It is a roadside stop, with Lake Hughes Road passing within a stone's throw of the water.

Lake Hughes Road runs right past it. You park and walk a few dozen steps. The land belongs to the Forest Service as part of the Angeles, and the elevation is modest, foothill country at around two thousand feet. Winters bring no snow at all. Annual rainfall is low, the usual dry Southern California pattern, so the surrounding country will be parched for most of the year.

Best months on record run December through February, and for a warm spring in hot country that makes sense: the water feels better when the air is cool. Access is roadside, with no hike involved. Upper Shake Campground is the nearest campground on file, about six miles away. No fee is recorded. The temperature on file is one figure; springs drift, so expect some variation.
