Things to Do in Glen Ellen CA in September 2026
Harvest season descends on the Valley of the Moon. Here is what is happening in wine country this month.
September arrives in Glen Ellen like a slow exhale. The vineyards go bronze and gold, the air cools at dusk, and the pace of life in the Sonoma Valley shifts from summer buzz to harvest-season rhythm.

Whether you are spending a weekend or live here year-round, September is one of the richest months to explore this corner of Sonoma County. From landmark park events and live music pairings to winery experiences and outdoor art, the month delivers more than it lets on at first glance.
