6 Best Things to Do in Napa in September 2026
September is one of the best times to visit Napa Valley – the scenery is beautiful, and harvest is in full swing. These six experiences combine seasonal events with activities available throughout the month.
#1 Take a Sunrise Hot Air Balloon Ride Over Napa Valley
Start your day with a sunrise balloon ride. Napa Valley Aloft’s Premier Balloon Experience begins early when the valley is still cool and quiet. Guests are welcomed with hot beverages and pastries while the crew prepares the balloon, and you can often watch the envelope slowly inflate and come to life as the burners roar briefly against the morning stillness. Pricing is $280 per person midweek and $300 on weekends, with the actual flight lasting about 45 to 60 minutes and the full experience taking roughly four hours. Throughout the flight, pilots share local insights and point out landmarks below, making the experience feel both peaceful and personal. You’ll drift over vineyards, country roads, and patchwork fields that glow in soft sunrise light.
Dress in layers, wear closed-toe shoes, bring sunglasses and a camera, and avoid scheduling a tight breakfast afterward, since landing spots and return timing can vary with the wind.
#2 Try a Grape Stomp at PEJU Winery
PEJU Winery in Rutherford offers one of the most immersive ways to experience Napa Valley during harvest season. The Harvest Festival and Grape Stomp on Sunday, September 20 runs from 11:30 a.m. to 2:30 p.m. and costs $185 per person or $165 for Club PEJU members; Saturday, September 19 is currently sold out. Guests can step into the barrels for traditional grape stomping, followed by a relaxed, family-style lunch paired with PEJU wines. The estate’s gardens are also well worth exploring before or after the festivities.
#3 Experience the Calistoga Harvest Table
Calistoga Harvest Table transforms Lincoln Avenue into a 1,000-foot-long open-air dining experience where visitors sit shoulder-to-shoulder with locals and fellow travelers for one shared evening in wine country. On Sunday, September 13, as live entertainment begins at 4 p.m., the scent of seasonal dishes starts to fill the air. Individual tickets are $175, while reserved tables for eight are $1,680.
Seating is first come, first served within each restaurant’s section, so arriving early gives groups the best chance to sit together and soak in the pre-dinner energy. With no dedicated event parking lot, you can use free downtown parking and then stroll into the heart of Calistoga, though rideshare options can become limited later in the evening.
#4 Attend a Napa Valley Harvest Party or Dinner
Harvest parties range from relaxed dinners to black-tie celebrations. Monticello Vineyards hosts its Harvest Party and Lobster Boil on September 12 from 5 to 8 p.m. for $199, or $179 for club members. V. Sattui’s 40th Annual Harvest Ball follows September 19 from 5:30 to 11:30 p.m.; tickets are $395 for non-members and $350 for members, with black-tie attire expected.
Pick one major evening event rather than stacking reservations, especially on September 19 when several events overlap.
#5 See Live Music at Blue Note Napa Summer Sessions
Blue Note Napa Summer Sessions brings live outdoor concerts to The Meritage Resort and Spa. September 2026 performers include Diana Ross, Con Funk Shun with Lenny Williams, Babyface, Kenny Wayne Shepherd Band, Jon B., and Jeff Dunham. Shows generally begin at 7 or 8 p.m.; ticket prices vary by artist and section. The venue is outdoors and rain or shine, so bring a light layer. Advance parking is $18 plus fees versus $25 plus fees on show day; reserved seating is the easier choice if you do not want a standing-room lawn section.
#6 Visit a Napa Valley Winery During Harvest
Hill Family Estate is a great harvest-time winery stop for visitors who want a more personal, farm-driven experience alongside their tasting. During harvest, you’re not just sampling wines; you’re seeing how the season’s work in the vineyards translates directly into what’s in your glass. The estate winery offers $75 tastings daily by appointment at 10 a.m., 12:30 p.m., and 3 p.m.; the fee is waived with a three-bottle purchase, and appointments are limited to eight guests, which allows the hosts to share more detailed stories about the grapes, the farming decisions, and the vintage as it unfolds.

Tips for Visiting Napa in September, Including Labor Day Weekend
For 2026, Napa Valley Labor Day festivities weekend runs September 5–7 and overlaps with Blue Note performances on Saturday and Sunday. September and October are among Napa Valley’s busiest harvest months, so reserve lodging, balloon flights, winery tastings, and ticketed events early. Pack layers for cool mornings and evenings even when afternoons reach the mid-80s. Group each day geographically—for example, Yountville with Rutherford or Calistoga with St. Helena—and arrange evening transportation in advance for up-valley events.
Make the Most of Napa in September
The best September trips in Napa are the ones that let you relax and enjoy. Instead of trying to pack the day with back-to-back plans, build in space for the rhythm of harvest season and the simple pleasure of being in the valley. A sunrise balloon ride with Napa Valley Aloft is a stunning way to begin, drifting quietly above the vineyards before the day fully wakes. From there, you might move into a relaxed winery tasting, take part in a grape stomp, linger over a long, unhurried dinner, or end the evening at a concert as the light fades. Aim for one or two meaningful reservations each day, and leave the rest open so you can follow the season’s pace instead of rushing through it.
