Massachusetts, often associated with historic charm and delectable seafood, holds a lesser-known secret: natural hot springs.

Due to the specific geological makeup of Massachusetts, true "hot springs" – those exceeding 140°F (60°C) – are rare. However, several natural springs with comfortably warm water temperatures exist and are popularly referred to as hot springs.

Best Time to Go: Spring (March – May) and fall (September – November) offer the most comfortable soaking experiences with pleasant weather and moderate crowds. Summers can be hot and humid, while winters can be chilly.

1. Sand Springs Pool and Recreation Center (Williamstown)

Sand Springs Pool & Recreational Center is an outdoor community pool in Williamstown. Upon arrival, visitors will find a small swimming pool and a hot tub that receive water from underground natural springs.

Sand Springs is the site of one of the oldest spas in North America. It is believed that Native Americans from the Five Nations made use of the spring as a water source and a medicine spring.  Arrowheads and other relics of a Native American encampment have been found on the site. A world-renowned soda and spring water bottling company has operated on the site since 1894.

Sand Springs is one of the only thermal springs in New England. Water originates from the Domlet in Pownal, VT and descends to a depth of approximately 2800 feet. 

For many years it has been a hot spot for the artists from the Williamstown Theatre Festival and locals alike. It now operates as a non-profit recreational center, aiming to preserve its historic character and charm.

Nestled within the Pleasant Valley Wildlife Sanctuary, Bowers Springs offers a unique experience. The iron-rich waters have a distinctive reddish hue, and the secluded location fosters a sense of tranquility. While the water temperature is cooler than traditional hot springs, the natural beauty and historical significance make it a worthwhile visit.

Bowers’ Springs is one of Bolton’s most popular conservation areas due to the scenic ponds, flat grassy fields suitable for picnicking and well distinguished trails connecting on to the Vaughn Hills/Hansen conservation areas, another popular area with miles of scenic trails.

No swimming is permitted in the ponds except by the Tom Denney Nature Camp during the summer months.

Bluebirds are attracted to this property and can be seen perched on the nest boxes that were constructed by a local 4-H group.
