Maine has no naturally occurring hot springs. The state's crystalline Appalachian bedrock, extensively glaciated and lacking recent volcanism or significant fault-hosted geothermal circulation, does not produce natural hot water at the surface. No historic hot or warm mineral spring resorts of consequence have been recorded. Travelers searching for hot springs in Maine, hot springs near Portland, or hot springs near Bangor will find no in-state options. The closest true hot springs are Berkeley Springs, West Virginia (approximately 11 hours by car) and Bath County, Virginia (approximately 13 hours). A handful of Maine spas offer heated seawater (thalassotherapy) pools and cedar hot tubs, but these are not naturally geothermal. Reviewed and updated June 2026.
