The park is located on the grounds of the former Metropolitan State Hospital, which operated from 1927 to 1992.
The spray deck uses a recirculating water system that is activated by sensors, ensuring water flows only when children are actively playing.
The facility is part of the larger Beaver Brook Reservation, which spans approximately 59 acres across Belmont and Waltham.
The reservation contains a designated 'accessible' trail that connects the playground area to the more rugged woodland paths.
The site was once part of a larger tract of land known as the McLean Hospital grounds before being acquired by the Commonwealth.
Beaver Brook - Spray Deck & Playground is a popular seasonal recreation facility located within the Beaver Brook Reservation in Belmont, Massachusetts. The site features a centralized water-based spray deck designed for children and a surrounding playground area. It is managed by the Massachusetts Department of Conservation and Recreation (DCR). The facility provides accessible restrooms and picnic benches for families. The spray deck operates primarily during the summer months to provide relief from warm temperatures. The surrounding reservation offers additional walking trails and wooded areas distinct from the playground section. The area is situated on the property of the former Metropolitan State Hospital campus, which serves as a historical backdrop. Parking is available on-site, though it can reach capacity during peak summer days.
The perimeter fence of the spray deck provides a clear view of the water features with the surrounding greenery of the reservation in the background.
