Now: Centered by a commercial area near the intersection of Diamond and Bosworth Streets, Glen Park is slightly more isolated than some of the central neighborhoods - hills and blocks of residences separate it from Noe Valley to the north and Bernal Heights to the east. Glen Canyon Park is a 70-acre city park featuring a deep natural canyon with walking paths leading up into Diamond Heights, and recreational facilities at its southern entrance.

Then: Most of the streets and homes along the Glen Park hillsides began to be built around the 1890s, when the railroad connected the relatively isolated area with the Downtown district.
