Park Overview

Prospect Hill Park is located on the west side of Waltham near Route 128 and is accessible by public transportation. It is a large, wooded park with dramatic topography containing two main summits.

The higher summit, Big Prospect, is the second highest point in the vicinity of Boston, at 485 feet. The lower summit, which measures 435 feet, is known as Little Prospect. Both summits provide some of the best views of the Boston basin.

Prospect Hill Park’s trails pass through woodlands that include a variety of flora and fauna. The park also contains several vernal pools that make it a lovely place to take long hikes.


Waltham’s Park Commission, formed in 1892, took on the task of acquiring land for Prospect Hill Park by requesting $20,000 a year later from the Board of Aldermen.
Early improvements included pedestrian paths, stone steps, camp sites, fences, and areas for picnics and other amenities to allow people to enjoy the park. The park was well maintained through the early years. However, after World War II, attention and care for the park began to decline. During this period additions were made to the park that detracted from its natural state.  In 1952, the United States Air Force constructed a research building for “observation and radar experimental purposes.” When the Air Force stopped using the building in the late 1990s it was demolished and most of the site was restored to a natural state. However, at the request of the City of Waltham, the radar tower was left standing. Communications equipment for various City departments is now mounted on the tower as well as the Waltham Amateur Radio Association’s repeaters.
A fire tower was originally located on Big Prospect but it was dismantled and a new fire tower was assembled on Little Prospect in 1963. The Little Prospect fire tower was finally removed in 2012.
In 1974, the City of Waltham constructed two water tanks above the ski area. These tanks are prominently visible today.
As the largest and oldest public open space in the City, Prospect Hill Park has been a source of pride and a focal point of the community since its creation.  In 1997, A Master Plan for the Restoration and Improvement of Prospect Hill Park was developed.  Its ten phases are aimed at improving the park’s condition and encouraging appropriate use. As of 2013, the City of Waltham is in Phase III of this plan.
