Are there hot springs in Massachusetts?

No. No natural hot springs reach the surface in Massachusetts. The one warm spring on record, Sand Spring in Williamstown, comes out warm rather than hot and feeds a swimming pool that opens in summer.

The nearest water that surfaces hot is in Bath County, Virginia, about 470 miles from Springfield and 550 miles from Boston in a straight line. For a winter soak closer to home, The Porches Inn in North Adams keeps an outdoor pool and hot tub open year-round.

How far are hot springs from Boston and Springfield?

Western Massachusetts is about 80 miles closer to Virginia than Boston is.

Both cities are a long drive from any hot spring, so most people treat Bath County as a destination in itself rather than a stop.

Sand Spring: Massachusetts' one warm spring

Sand Spring rises near the Hoosic River in Williamstown, in the far north-west corner of the state, and it is the only Massachusetts spring on NOAA's list of US thermal springs. Its water comes out in the low 70s °F all year: pleasantly warm for a swim, but far below the 100°F and more of a true hot spring.

People have bathed here for a long time, and in the 1800s and early 1900s the spring supplied an inn and bathhouse. Today it feeds the Sand Springs Pool, run by a local nonprofit, which usually opens from late June to early September. Check its season before you go; in winter there is nowhere to get into the spring water.

Any hot tub you find in the state is capped by law: Massachusetts' sanitary code for pools limits hot tubs and other special-purpose pools to 104°F.
