Davidson is adjacent to Belrose and Frenchs Forest and is located on the eastern edge of the Garigal National Park, approximately 15 kilometres (9.3 mi) from the Sydney CBD. The Eucalyptus trees and Liquid Ambers that line the streets of Davidson provide a pleasant backdrop for those living in the suburb. They also provide a haven for large numbers of native birds such as Kookaburras, Galahs and Rainbow Lorrikeets.
Davidson has many parks. The suburb adjoins Garigal and Kur-ing-gai Chase National Parks and in addition, has numerous other reserves suitable for picnics, ambling and quiet moments of reflection. These include McFarlane Reserve, Maitland Street Reserve, Aranda Place Reserve and Richard Healy Oval, to name but a few.
