The suburb is situated to the north of State Highway 16 and the campus of Unitec New Zealand and to the west of the suburb of Western Springs. It is largely sited on the triangular peninsula, which extends north into the harbour for 1800 metres. The soil is mostly clay without the overlay of volcanic material which covers much of the Auckland isthmus; this means the vegetation of the area is less lush than some of the other suburbs of Auckland.
Visible from Coyle Park is Meola Reef, which is situated to the east of the Point Chevalier peninsula and bordering the suburb of Westmere. Meola Reef is an outcrop of black basalt rock which extends some distance north into the Waitemata Harbour. This is the end of the lava flow emanating from Te Tatua-a-Riukiuta, a volcano several miles south of this area. Formerly a landfill site, it has now been rehabilitated as a park and nature reserve. Other parks in the suburb include Walker Park, Eric Armshaw Reserve and Coyle Park. The latter is located at the northern tip of the peninsula.
