## About Newsom Springs

A couple of miles outside Arroyo Grande in San Luis Obispo County, Newsom Springs comes out at about the temperature of a warm bath. The road that leads there carries its name. That is most of what the record says. No owner is listed and public access has not been established, so settle the access question before you drive out.

The spring sits in low coastal hills a little over six hundred feet up, a short walk of a hundred yards or so from Newsom Springs Road. Rain comes in winter and adds up to a modest total, and snow does not figure at all. Beyond that the file says nothing about the land unit or what the outlet looks like. Arroyo Grande is the nearest town, a couple of miles away.

Winter is the listed season. Water near body heat will feel pleasant on a cool January day and unremarkable in summer. Neither the owner nor the access status is on record, so look for posting and ask in Arroyo Grande. American Canyon is the closest campground listed, about seventeen miles off. There is no fee on record.
