The CDP extends north to a line running between Federal Street and Garrison Farm Road, then runs east so that it passes north of Elmwood Drive and Megan Drive.

The northern border then runs south of Wagner Way, Joel Path, and Bonnie Lane, and north of Monroe Drive and Jackson Drive, until it reaches Greeley Street, the eastern extent of the CDP.

The border turns west to follow Pelham Road, then turns south on New Hampshire Route 3A (Lowell Road) to Third Brook, which it follows west to the Merrimack.

[3] Route 111 is the main east-west road through the CDP, leading west across the Merrimack River into Nashua and east 9 miles (14 km) to Interstate 93 in Windham.

New Hampshire Route 102 begins in Hudson and leads northeast 10 miles (16 km) to Derry.
