Mary Cummings Park has an unusual history: left in trust for public use by Mary Cummings, Boston became the trustee, and never figured out how to handle this park. But in the last few years, Boston partnered with The Trustees to have them manage the park.
Mary Cummings has extensive wildflower and grassy meadows, which is unusual; the wildflowers stands can be huge in summer. In addition there is a large wetland with walkways, a boardwalk over one large area, plus many kinds of mature forest.
The park is mostly in Burlington, partly in Woburn, but here we group it with its sister park, Whispering Hill Woods, which is entirely in Woburn.
