Pour ginger ale and vodka into a blender. Add peaches and ice. Cover and blend until mixture is smooth and no chunks remain. If mixture is too thick or difficult to blend, add an additional 2 ounces of ginger ale.
Pour into highball glasses and serve immediately.
Notes
If peaches are frozen out of season, they may not be sweet enough on their own. As needed, add a splash of simple syrup to mixture while blending.
Vodka can be substituted with rum.
Ginger ale can be substituted with ginger beer for a stronger ginger flavor.
To make non-alcoholic - replace vodka with additional ginger ale.
