Updated September 1, 2026. Denville runs a full calendar for a town of roughly 16,000 people. Broadway closes for a street festival in June, Gardner Field fills with food trucks in October, and the farmers market takes over Sunday mornings from spring into fall. This is the Denville Now guide to the events that come back every year, roughly in the order they happen, with links to our coverage of the most recent edition of each. We keep this page updated rather than replacing it, so it is worth bookmarking.
Spring
Denville Farmers Market
Sundays in downtown Denville. The regular season opens in early May and runs into the fall, bringing local growers, bakers and food producers to town alongside the Broadway shops and restaurants. It is reliably the busiest thing in Denville on a summer Sunday morning. See our coverage of the 2026 season opening.
Denville Rotary Street Festival
Early June, on Broadway in downtown Denville, free to attend. The biggest single day in Denville. The Rotary Club of Denville closes Broadway for arts and crafts booths, food vendors, retail and non-profit tables, children’s rides, a beer garden and a live entertainment stage. It has run for more than four decades. See our coverage of a recent street festival.
Garlic Fan Fest
June, at Todd Johnson Field. A food festival built entirely around garlic, with local food vendors, cooking demos, live music, giveaways and family activities. See our coverage of the 2026 Garlic Fan Fest.
Summer
Denville Days
Early July, around the Fourth. The town’s summer carnival stretch. Schedules can shift for weather, and in 2026 extreme heat reshaped the lineup, so check the current year before you go. See our coverage of the 2026 Denville Days schedule.
Music in the Park
Summer evenings. Free outdoor concerts from local and regional acts. See our coverage of a recent Music in the Park night.
Mount Tabor Children’s Day Parade
August, in the historic Mount Tabor village on the Denville border. One of the oldest continuously running traditions in the area, held in the Methodist camp meeting community founded in 1869 and now a National Register historic district. See our coverage of the 2026 Children’s Day parade.
Fall
Denville Art in the Park
Early September. Local artists, makers and live art in a park setting, on a Sunday at the end of the summer. See our coverage of Art in the Park.
