Spring is wildflower season in wine country, and the best picnics follow the bloom into the parks. In Sonoma Valley, Sonoma Valley Regional Park, Jack London State Historic Park and Sugarloaf Ridge State Park all have picnic tables and spring flowers, and all three allow wine in their picnic areas unless a ban is posted. Elsewhere, head to Trione-Annadel, Crane Creek or Helen Putnam in Sonoma County, Skyline Wilderness Park in Napa, or the Sonoma Coast. The show starts even earlier in the vineyards, where wild mustard turns the rows yellow from January to March. On peak weekends, book group sites, reserved winery tables and boxed lunches ahead.
What blooms when
| When | What you'll see | Good picnic spots |
|---|---|---|
| January–March | Mustard between the vineyard rows (Napa's peak is usually mid-February) | Vineyard Park, Pestoni, Oakville Grocery |
| From January | Early wildflowers along Sugarloaf's trails | Sugarloaf Ridge State Park |
| February–May | Wildflower walks in the county regional parks | Sonoma Valley, Crane Creek, Helen Putnam, Foothill |
| March–April | Poppies and lupines | Sonoma Valley Regional Park, Crane Creek |
| March–May | Gray whales migrating off the coast | Bodega Head |
| Mid-April to mid-June | Rhododendrons at Kruse, next to Salt Point | Salt Point State Park |
| Early summer | Lavender | Matanzas Creek Winery |
Sources for the timing: Visit Napa Valley (mustard), Sonoma County Tourism (poppies, lupines and whales), Sonoma County Regional Parks and the Sonoma Ecology Center (Sugarloaf). Bloom times shift with the weather, so check a park's latest report before you go.
Mustard season in the vineyards
Growers plant mustard between the rows as a cover crop that protects and feeds the soil. Visit Napa Valley suggests driving Highway 29 or the Silverado Trail to see it, and asks visitors to pull safely off the road, stay off private property and be mindful of the dormant vines.
Winter picnics need a dry day and a jacket (Napa averages a 60°F high from December to February), but a few spots put you right beside the yellow rows:
- Vineyard Park in Yountville: a free lawn facing the vines, where beer and wine are allowed.
- Pestoni Family Estate in Rutherford: a free picnic lawn beside its vineyard for guests enjoying its wines (outdoor tastings are weather permitting).
- Oakville Grocery: customer picnic tables and a patio among the Oakville vineyards.
- Napa Cellars (Thursday–Monday) lets you bring food to an outdoor tasting, and Madonna Estate in Carneros has a picnic area beside its vines.
Yountville
Vineyard Park is about as wine-country as a free public picnic gets: a quiet lawn with vineyard and Stags Leap views, where town code lets you open a bottle of wine. There are only a few tables, so bring a blanket.

Carneros
A long-running family winery in Carneros growing organic, dry-farmed grapes. Unusually for Napa, it still takes walk-ins and pours at an old-fashioned stand-up bar. There's a picnic area for lunch, a $30 tasting, and a welcome for kids and dogs, making it one of the best budget picnic stops at the south end of the valley.

Wildflower parks in Sonoma Valley
Sonoma Valley Regional Park has a grassy, oak-shaded picnic and barbecue area at its Highway 12 entrance, and more tables along the paved Valley of the Moon Trail, where poppies and lupine bloom in spring. Regional Parks recommends its Woodland Star, Buttercup and Milkmaid trails. Wine is allowed, parking is $8, and there's a fenced off-leash dog park by the lot.
Jack London State Historic Park describes spring as mild, with periods of rain and an abundance of wildflowers. Tables are scattered around the old Beauty Ranch, and the Oak Grove, looking over the vineyard, can be reserved for $150 plus parking ($15 per car).
Sugarloaf Ridge State Park is busiest in spring and fall. The Sonoma Ecology Center, which helps run the park, says flowers start blooming along its trails as early as January, and it tracks the Vista, Bald Mountain and High Ridge trails among others. Every picnic site has a barbecue, and many sit along Sonoma Creek ($10 per car).
Glen Ellen
A shady oak-woodland park on Highway 12 at the edge of Glen Ellen, with a grassy picnic and barbecue area at the entrance and an easy paved trail for an after-lunch stroll. Wine is allowed under county rules, and the off-leash dog park next to the lot makes it one of the valley's best picnic stops for dog owners.

Glen Ellen
Jack London's former Beauty Ranch combines history, vineyard views and 29-plus miles of trails with some of the valley's most varied picnic spots, including a reservable oak grove with barbecue stands.

More wildflower parks in Sonoma County

- Crane Creek Regional Park, near Rohnert Park: its Creek, Lupine and Poppy trails circle large wildflower meadows, with tables scattered under oaks. Bring water, since there's no drinking fountain.
- Helen Putnam Regional Park, Petaluma: Regional Parks says its 6 miles of trails are "alive with wildflowers," and there's a picnic area and gazebo by the playground.
- Foothill Regional Park, Windsor: known for its lupine, with tables around three small ponds. It may close on high-wind days.
All four allow wine under state or county rules. Parking is $8.
Santa Rosa

Spring picnics in Napa's parks
Skyline Wilderness Park on Napa's southeast edge invites you to hike "through wildflower fields" with views of the valley's vineyards, and its Martha Walker Native Habitat Garden holds nearly 200 native species on 2.5 acres. The picnic grounds are by the entrance ($6 per car). The park publishes no alcohol rule, so call before bringing wine.
Bothe-Napa Valley State Park, between St. Helena and Calistoga, is at its best in spring and fall: California State Parks says the park and its surroundings are "probably at their finest" then. Its roughly 50 shaded tables with stoves sit near Ritchey Creek, where the Redwood Trail winds past ferns ($10 per car).
The Sonoma Coast in spring
California State Parks calls the Sonoma Coast's spring wildflower displays "spectacular," and March to May is gray-whale migration season. Bodega Head has about ten free tables on its whale-watching cliffs. At Goat Rock Beach, harbor seals pup from March to August, so stay at least 50 yards away. Farther north, the rhododendrons bloom next to Salt Point State Park from roughly mid-April to mid-June. Pack a windproof layer for all three.
Sonoma Coast
The rocky headland at the mouth of Bodega Harbor is the Sonoma Coast's classic whale-watching lookout, and it's free. Pack a windproof layer, claim a table at the west lot, then walk the 1.9-mile Bodega Head loop for views over Bodega Bay and the open ocean.

The dramatic, easy-to-reach beach at the mouth of the Russian River, just south of Jenner, with free parking, tables and restrooms.

Spring weather and longer days
Visit Napa Valley says spring highs run from the mid-60s in March to the mid-70s in May, and rain is possible into March. Sonoma County Tourism puts March and April highs in the low-to-mid 60s, with a mix of sunny days and light rain. Trails and lawns can stay wet after storms, so bring a blanket with a waterproof back.
Clocks spring forward on the second Sunday of March (March 14 in 2027), and the evenings stretch out fast. Sunset in Napa moves from 7:15pm on March 14 to 7:45pm in mid-April and 8:13pm in mid-May, per the U.S. Naval Observatory. Skyline Wilderness Park stays open until 7pm once daylight saving time starts.
Picnic programs that open in spring
- Benziger's terrace picnic tables and Michel-Schlumberger's Estate Picnic open in March.
- Kendall-Jackson's picnic tables and Dry Creek Vineyard's picnic lunch package start in April, and Gloria Ferrer's walk-in Al Fresco service (Friday–Sunday) in May.
- Triple Creek Horse Outfit's ride and picnic at Jack London ($215) and the Napa Valley Bike Tours lavender and olive oil farm picnic ride ($295) run April–October.
- Sonoma's Tuesday Night Market returns to the Plaza in May, and the St. Helena Farmers' Market starts its Friday season the same month.
Book ahead for peak weekends
Visit Napa Valley notes that March to May is less crowded than summer at the most popular wineries, but picnic spaces are small and holiday weekends fill. Plan early for Easter (March 28, 2027), Mother's Day (May 9) and Memorial Day weekend (May 29–31). Sonoma County Tourism also lists the Passport to Dry Creek Valley in April and the Healdsburg Wine & Food Experience in May, so plan ahead if you're headed to Healdsburg then.
- Group sites: Sonoma County regional parks book 12 months to 3 days ahead ($75 for up to 99 people), and Maxwell Farms' group sites book up in spring and summer. Jack London's Oak Grove is $150, and Sugarloaf's day-use areas are $50 on ReserveCalifornia.
- Winery tables: reserve spots like Matanzas Creek ($25 on weekdays) or Gary Farrell ($55) a few days ahead.
- Food: order boxed lunches two days ahead. See where to buy picnic food in Napa Valley and in Sonoma County.
- Closures: Bartholomew Park closes on Easter Sunday.
