Nestled among the apple orchards of Western Sonoma County, the Hallberg Butterfly Gardens cover nine acres of overgrown vines and thickets, flowering pathways and meadows. We welcome individuals, small groups, and classroom visits, by appointment. The Gardens are open for guided tours from April 1 to October 31. Appointments are offered Wednesday through Sunday, between 10 am and 4pm. The Gardens are closed between November 1 and March 31.
