No info kiosk
Not confirmed at any entrance.

Worth knowing

  • The hospital operated from 1927 until its 1992 closure; a 54-acre parcel of the former grounds carries a conservation easement, and the city separately owns 51 non-wooded acres near Trapelo Road plus the 7-acre Mackerel Hill Conservation Area nearby.

Common questions

Where do I park, is it obvious?
There is no single marked lot; most visitors reach the carriage roads on foot from neighboring conservation land such as Falzone Park or the Belmont side at Rock Meadow.
