Avalon is located within the Nutana Suburban Development Area. It is bounded by Ruth Street to the north, Circle Drive to the south, Idylwyld Drive to west, and Clarence Avenue to the east. Roads are laid in a grid fashion in the north part of the neighbourhood, while the south part features crescents and cul-de-sacs. The community has the distinction of being either directly connected by, or directly adjacent to, all four major roadways leading to downtown: the Idylwyld Freeway (via Lorne Avenue), Victoria Avenue (via Wilson Crescent), Broadway Avenue and Clarence Avenue.
