1. Pick Your Own Pumpkin at an East Bay Farm

Pumpkin patches are the heart of fall in the East Bay, and the region has options for every kind of visitor, from full-blown fall festivals to quiet, low-key farm stands.

Dell'Osso Family Farm is a longstanding East Bay tradition that draws thousands of visitors every October. Expect haunted houses, corn mazes, pig races, gem mining, and hayrides, plus a food court dishing out fall favorites like apple-spiced donuts and funnel cakes.

Smith Family Farm in Brentwood is a great pick for families who want a working-farm feel. Admission runs around $16 (kids under 2 are free) and covers a pumpkin of any size plus barnyard animals, an herb garden, and live music.

For a low-key, neighborhood option, head to Westbrae Pumpkin Patch tucked into a nursery in North Berkeley. It's one of the only patches actually inside Berkeley, open daily from late September through Halloween with no admission fee and proceeds go to a local elementary school.

Tip: Most East Bay pumpkin patches open the last weekend of September and run through Halloween, with weekend-only extras like pony rides and hayrides, plan a Saturday visit if you want the full experience.

2. Get Lost in a Corn Maze

Corn mazes turn a pumpkin patch trip into a genuine outing. G&M Farms Cornfield Maze and Pumpkin Patch has been featured on The Late Show with David Letterman and was voted Best Seasonal Attraction in the East Bay by Diablo Magazine. Beyond the headline maze, the farm has a free straw bale maze, a corn box, and farm animals, with weekend paid extras like pony rides, a cow train, pedal carts, jumping pillows, and a hayride.

3. Hike Mount Diablo State Park for Fall Views

Mount Diablo is the East Bay's signature peak, and fall (with cooler temperatures and clearer skies) is one of the best times to climb it. The mountain has trails for every fitness level, from easy strolls to the demanding Grand Loop, which delivers sweeping 360-degree views on a clear day.

Nearby, Morgan Territory Regional Preserve is a local favorite for fall hiking. The Old Finley Road, Highland Ridge, Black Hills, and Sulfur Springs Loop winds through rolling hills, and cooler fall weather makes it an especially good pick since the trail tends to stay sunny.

4. Chase Fall Foliage at Tilden Regional Park

You don't have to drive to Napa for fall color. Berkeley's Tilden Regional Park is a sprawling, 2,000-plus-acre forest, and the best foliage shows up at its botanic garden, where cottonwood, dogwood, and other deciduous trees turn brilliant shades of yellow and orange. Admission is free. Pair the garden with a stop at the park's Little Farm, and you've got a half-day outing that works for toddlers and grandparents alike.

5. Explore Diablo Foothills and Las Trampas for More Fall Color

Beyond Mount Diablo itself, the surrounding regional parks offer their own foliage payoff. Diablo Foothills Regional Park in Walnut Creek covers over 1,200 acres of gentle slopes and steep inclines, with oak groves that turn color across open meadows and chaparral each autumn.

Further south, Las Trampas Regional Wilderness offers panoramic viewpoints over the East Bay framed by fiery fall foliage, and Pleasanton Ridge rounds out the Tri-Valley's best leaf-peeping spots with its own network of rolling-hill trails.

6. Sip Wine During Livermore Valley Harvest Season

Fall is the season to visit Livermore Valley. Harvest season here runs from mid-August through late November, and every autumn the region comes alive as vintners bring in the crop, transforming the landscape from lush green to a sea of gold, red, and amber. Nearly 50 wineries across the Tri-Valley open tasting rooms to visitors during this stretch.

The marquee event is TASTE: The Livermore Valley Wine Experience, returning October 15–18, 2026, with vineyard hikes, winemaker tastings, and harvest-focused events across the valley. Individual wineries add their own programming too, Wente Family Vineyards, for example, runs a relaxed small-group fall bike tour along paved vineyard paths, including a ride through its Chardonnay vineyard along Arroyo Mocho Creek, capped with a curated tasting flight and charcuterie board.

7. Browse the Harvest Festival Art & Craft Show in Pleasanton

If you'd rather shop than hike, the Harvest Festival Original Art & Craft Show at the Alameda County Fairgrounds is an East Bay fall staple. It runs Friday, October 23 through Sunday, October 25, 2026, and features thousands of handmade items such as jewelry, ceramics, hand-turned wood, and specialty foods. General admission is $9 ($7 for seniors and military), with free entry for kids twelve and under.

8. Catch a Neighborhood Fall Festival

Smaller community festivals pop up across the East Bay all September and October. The Castro Valley Fall Festival runs Saturday, September 12 through Sunday, September 13, 2026, from 10am to 6pm along Castro Valley Boulevard, with community booths, food, and local vendors. Check your own city's parks and recreation calendar. Lafayette, Danville, and San Ramon all run similar street-fair-style events through the season.

Planning Your East Bay Fall Trip

A few tips to get the most out of the season:

• Go on weekdays when you can. Pumpkin patches and wineries get significantly busier on weekends, especially in October.
• Layer up for hikes. Mornings in the East Bay hills can start cool and foggy even when afternoons turn warm, Mount Diablo and Morgan Territory in particular see big temperature swings.
• Book harvest-season winery events early. Popular Livermore Valley events, especially around TASTE weekend, tend to sell out in advance.
• Check patch hours before you go. Many pumpkin patches reserve hayrides, pony rides, and other add-ons for weekends only, and some smaller farms have limited weekday hours.
