This wild garden, tucked into Chestnut Hill and abutting Webster Woods, is on the National Register of Historic Places. Its paths wind around a stream and lagoon-like pond with water features designed by Warren Manning, who formerly worked for the Olmsted studio. Explore this hidden gem of a conservation area with its land steward, Michele Hanss of the Friends of Houghton Garden. The walk will be rescheduled in the event of steady rain. Meet at the park entrance near 207 Suffolk Rd. Trip Leader: Michele Hanss (617-285-9107)
