Perhaps the largest of the Hamilton's four hamlets, Hubbardsville is located near the "four corners" of Poolville Road (Route 89) and Green Road in the northeastern quadrant of the Town. A post office with a general store and gas station serves as the center of the hamlet, which sits in an attractive valley surrounded by hills. 
Hubbardsville is mostly residential, and has a number of Victorian-style homes. Several years ago, a housing rehabilitation program funded by the U.S. Department of Housing and Urban Development provided homeowners with grants to make necessary repairs. Hubbardsville Manor, a home for the aged, is operated in the hamlet. Other businesses located in the vicinity include a nursery/greenhouse and a campground with facilities for miniature golf. A volunteer fire department and Graham Cemetery are also located in Hubbardsville.
