Greenfield began acquiring land for Rocky Mountain Park as early as 1907.

Rocky Mountain Park is five contiguous parcels that include hiking trails and the popular Poet’s Seat Tower. It is a unique forested ridge that separates the Connecticut River from Greenfield that stretches nearly two miles in a north-south fashion. Rocky Mountain Park is serviced by a small parking area at Mountain Road and Parkway Street. Parkway Street is a dead-end, unimproved surface that provides auto access up the ridge to the Poets Seat Tower Area. Additional parking area exists at Poets Seat Tower but is only accessible via auto during the summer months.

The park attracts many local residents and visitors alike. The park currently consists of 3 trails which are extensions of a local and regional trail network. The local trails connect a few of the existing parks including Abercrombie Field, Highland Park, and Temple Woods designated by red, blue, and yellow trail markers. The regional trail, The Pocumtuck, connects Greenfield to the Sugarloaf Mountains in South Deerfield and links with the Blue Trail in the Rocky Mountain Park creating a regional link to the south.
