Colinton and Fairmilehead occupy the southwestern edge of the City of Edinburgh. The area is largely residential, characterised by a mix of housing from different periods. It is bordered by green spaces, including the Pentland Hills Regional Park to the south. The Water of Leith flows through the northern part of the ward, providing a natural corridor. Local amenities serve the community's needs, with several schools and shopping parades present.
The area is defined by its topography, with many streets offering views across the city. A notable feature is the former Colinton Tunnel, now part of a walking and cycling path decorated with a mural depicting local history. This path follows the old railway line, connecting to wider networks. The community maintains a distinct identity, with local groups active in preserving the area's heritage and natural environment.
