Poland Spring Preservation Park

Perhaps the most famous name in American water, Poland Spring’s history as a therapeutic destination dates back to the 19th century. While you can no longer "soak" in the commercial source, the preservation park and nearby inns offer a glimpse into the historic mineral culture of the region.
