The Halls Valley Astronomical Group is a division of the Friends of the Grant Ranch Park, the volunteer association at Joseph D. Grant County Park. The Friends of the Grant Ranch Park has been working in Grant Park since 1977, providing interpretive programs for the public and aiding park staff. 

Organized in 1982, the Halls Valley Astronomical Group has been providing the public with monthly astronomical observing programs for over 33 years. HVAG Starparties make astronomical telescopes and interpretation available to the public under the dark skies of Halls Valley.
