Aldan is a compact Delaware County borough located just west of Philadelphia, surrounded by communities including Clifton Heights, Collingdale, and Upper Darby. Its streets are primarily residential, with a mix of traditional detached homes, twins, and other housing styles characteristic of the older inner-ring suburbs surrounding Philadelphia.

The borough is connected to the surrounding region by SEPTA trolley and bus service, while Baltimore Pike and MacDade Boulevard provide access to shopping, dining, and neighboring Delco communities. Local parks and recreation spaces are incorporated throughout the borough, and its central Delaware County location places Media, Philadelphia, and other parts of the western suburbs within convenient reach.
