Napa's Vine Trail Runs Twelve and a Half Miles Straight. Except for Soscol Avenue.

"We haven't caught up with the public use of this park." That's what Napa City Councilmember Liz Alessio told the room in January 2024, right before the council voted to let mountain bikes onto dirt trails at Alston Park for the first time in the park's history. Nearly two years later, that fight is over. A half-mile away in trail terms but a world away in bureaucratic terms, a different gap in Napa's outdoor life just started moving toward a fix after sitting unresolved for years.

If you've ridden or walked any real distance in Napa, you already know which one I mean. The Vine Trail looks finished on a map. It isn't, and the specific place it isn't tells you more about how this city actually plans and pays for public space than any ribbon-cutting photo does.

The Fight That Actually Ended

Alston Park has been Napa's default dog park for decades, 157 acres off Dry Creek Road with a fenced three-acre off-leash area called Canine Commons and miles of open, grassy trail. For just as long, city ordinance technically banned mountain bikes on anything but the paved and gravel roads there, a rule almost nobody followed and almost nobody enforced. Generations of Napa kids learned to ride off-road on those dirt paths anyway.

That mismatch between the rule and the reality is what brought the Napa County Bicycle Coalition to the council in January 2024. Executive Director Kara Vernor asked for a pilot: open the park's northern dirt trails, away from the off-leash dog area, to mountain bikes for six months and see what happens. The council approved it unanimously that January, and the pilot began that April. Dog owners at the meeting weren't thrilled. Alston is one of the few places in Napa where you can let a dog run and walk a trail without worrying about traffic or crowds, and some worried bikes would change that.

They didn't, at least not enough to matter. Napa's Parks, Recreation and Trees Advisory Commission reviewed the pilot data and cleared staff to make it permanent, effective October 16, 2025. The city updated signage. The northern section stays open to bikes. The off-leash Canine Commons in the southeast stays exactly what it's always been.

What Changed on the Ground

If you haven't been to Alston Park since before the pilot, here's what's actually different now:

• New signage in the northern section marks which trails allow bikes, replacing the old ambiguous status quo where the rule and the reality didn't match
• The off-leash Canine Commons and its surrounding trails were left untouched by the change, so nothing shifted for dog owners who stick to that part of the park
• The park still charges no entrance or parking fee and remains open sunrise to sunset, same as always
• The city is watching whether winter conditions call for seasonal adjustments, so this isn't fully locked in stone yet, just settled for now

What's worth noticing here isn't the bike trail itself. It's that a park governed by a decades-old conservation easement, one that's turned down lighted ballfields and expanded picnic areas at the ballot box before, found room to change through a data-driven pilot instead of a fight. That's a pattern worth remembering the next time something at the park comes up for a vote.

The Trail Everyone Assumes Is Finished

Now the other one. The Napa Valley Vine Trail is the region's headline outdoor project, a planned 47-mile paved path meant to run continuously from the Vallejo Ferry Terminal to Calistoga. Locals talk about it like it's basically there. It mostly is, in pieces.

The stretch that matters most if you live in the city of Napa runs 12.5 miles, continuous and paved, from John F. Kennedy Memorial Park north through downtown and out to Yountville. That's the section most people mean when they say "the Vine Trail," and it's genuinely good: river views for the first few miles out of Kennedy Park, then a run alongside the Wine Train tracks toward Yountville.

Buried in the middle of that 12.5-mile stretch, though, is a half-mile gap along Soscol Avenue between Third Street and Vallejo Street, right in the heart of the city. For that half-mile there's no dedicated path. You're on Soscol Avenue itself, sharing lanes with through traffic on one of Napa's busier arterials.

That gap has been known and unfixed for years. What changed recently is that the city posted the closure project for bid under job number ST18PW08 in its online planroom, the concrete sign that this particular fix is finally moving from planning document to construction schedule rather than sitting on a list.

Where the Rest of the Trail Actually Stands

Here's the honest state of things elsewhere on the route, because the Soscol gap isn't the only unfinished piece, just the one that touches daily life in the city most directly.

Napa Valley Transportation Authority materials describe the Calistoga-to-St. Helena section as the most recently finished, opened in August 2024 through Bothe-Napa Valley State Park. The Yountville-to-St. Helena piece, which would eventually stitch the whole valley together, is still working through funding and design. None of that changes what a Napa resident experiences this weekend. What changes your weekend is the half-mile in your own backyard.

Why a Half-Mile Outweighs Twelve

It's tempting to file the Soscol gap under minor inconvenience. Half a mile out of 12.5 sounds like rounding error. It isn't, because of where that half-mile sits.

The gap falls in the exact middle of the city's longest continuous trail segment, which means anyone riding from Kennedy Park toward Yountville, or walking the reverse direction into downtown, has to interrupt a quiet, protected ride to merge onto a live traffic lane. It's the one spot on an otherwise excellent route where the infrastructure doesn't match the ambition. A gap at either end of a trail is easy to route around. A gap in the middle breaks the trail in two, whether the map says so or not.

That's also why the bid posting matters more than its size suggests. This isn't a new grant announcement or a ribbon-cutting projection years out. It's the unglamorous, concrete step that comes right before dirt actually moves.

Picking Your Loop This Weekend

None of this means the trail isn't worth using now, just that knowing the gap changes how you plan around it.

• If you want an uninterrupted ride or walk with river views and no traffic crossings, start at Kennedy Park's boat launch and head north. The first three miles along the river are the best of the whole route before the trail eventually meets Soscol Avenue.
• If you'd rather skip the Soscol stretch entirely and still get real mileage, Kennedy Park connects to Skyline Wilderness Park's River to Ridge Trail, a 5.6-mile out-and-back with more elevation and fewer crowds.
• If you're taking a dog and want off-leash room without worrying about bikes, Alston Park's Canine Commons and surrounding on-leash trails are unchanged by the mountain bike pilot becoming permanent.
• If you're the one on the mountain bike, the newly permanent northern section of Alston Park is now clearly signed and legally yours to use, no more guessing where the old rule ended and the real use began.

Kennedy Park itself is worth knowing beyond its role as a trailhead. At 350 acres it holds picnic areas, athletic fields, a golf course, a playground, and a boat launch, which makes it as much a destination as a starting point.

The city's outdoor spaces aren't finished projects sitting still. They're in motion, some resolved through a quiet pilot program and a commission vote, others waiting on a bid posting to turn into actual construction. Knowing which is which is the difference between planning a Saturday morning around the map you think exists and the trail that's actually there.

If you're thinking about what it means to plant roots in a city that's still building out its own backyard, that's a conversation worth having. Joe Brasil has spent 18 years learning Napa block by block, gap by gap, and is glad to talk through what a home here is actually worth.
