Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Three clear, mineral-rich soaking pools set in a flat agricultural field west of the tiny town of Meadow, just south of Fillmore. Water is naturally heated (~90–100°F depending on pool and season); the largest pool is deep enough to swim. Privately owned but long open to respectful public day use under posted rules—no alcohol, swimsuit required, pack out trash.
