Ninety Longhorn Ridge sits inside a private, gated equestrian community in the eastern foothills of Napa Valley — eleven parcels, a private paved road, and miles of riding and hiking trails that run through the ridge. From the wraparound porch the view opens across rolling hills and vineyards to Lake Berryessa, and the sunsets are the reason people stop talking mid-sentence.
The house was built for gathering. An open floor plan runs from a chef's kitchen with commercial appliances through the great room, family room, and dining room — each of them opening to the outdoors. The primary suite does the same, so the line between inside and the ridge never quite settles.
Outside is where the property earns its reputation. A covered wraparound porch with its own fireplace faces the lake. Beyond it: a pool, a hot tub, a bocce court, a fire pit, and a full outdoor kitchen with BBQ, sink, and beer taps beside a covered dining area and lounge. It is a house that assumes you are having people over.
A three-car garage adds wall-mounted storage and a workshop. A separate ADU a few steps from the main house handles in-laws, guests, or a long-staying family member without anyone sharing a hallway.

From downtown Napa, take Trancas Street onto Monticello Road (Highway 121) and run about eight miles east. Roughly a hundred yards past Circle Oaks, Longhorn Ridge Road climbs to the right — a private, gated, paved road. Number 90 sits near the end of it. Twenty minutes to downtown Napa, minutes to the Silverado Trail and world-class wineries, and Lake Berryessa just over the ridge.
Napa County is a scarcity market by design. Agricultural and hillside protections sharply limit what can be built, and many large parcels cannot easily be subdivided — so estate and vineyard properties remain a small subset of an already thin inventory. Strict building codes and environmental zoning have kept overdevelopment in check for decades, which is precisely why the valley's land values have proven durable through multiple cycles.
The current market rewards buyers who move deliberately. Napa Valley's median sale price settled around $940,000 at the close of 2025, a modest correction from the 2024 peak, and homes sold for an average of roughly 96% of original list price — a meaningful shift from the 100%-plus ratios of the 2021–2022 peak. Mortgage rates retreated to near 6% in early 2026, their lowest since 2022. Translation: leverage is more balanced than it has been in years, and negotiation matters again.
For a buyer at this level, the thesis is straightforward. You are not buying square footage. You are buying acreage, privacy, and a gated position in an eleven-parcel community twenty minutes from one of the most recognized wine regions on earth — the kind of asset that cannot be replicated by new construction because the land to build it on is no longer being approved.
Market figures reflect Napa Valley and Los Angeles reporting current to early 2026 and are provided as general context, not as a forecast or an appraisal.
Longhorn Ridge is a private, gated equestrian community in the eastern foothills of Napa Valley, made up of only eleven parcels across roughly 800 acres. It has its own paved private road, a gated entry, and miles of horse and hiking trails running through the ridge. The community is governed by the Longhorn Ridge Owners Association.
About twenty minutes. From downtown Napa you take Trancas Street onto Monticello Road (Highway 121) and travel roughly eight miles east; Longhorn Ridge Road is the private gated road on the right, about a hundred yards past Circle Oaks. The Silverado Trail, Napa's wineries, and Lake Berryessa are all within easy reach.
65.46 acres. In a county where hillside and agricultural protections sharply limit what can be built and subdivided, acreage of this size adjoining protected open space is not something that comes to market often.
$420 per month ($5,040 annually) to the Longhorn Ridge Owners Association, which maintains the private paved road and the gated entry serving the community's eleven parcels.
Yes, and it is a serious one — not a converted garage. The detached accessory dwelling unit is a fully finished modern residence with its own kitchen, living area, vaulted ceilings with skylights, polished concrete floors, and a built-in bunk room. It works as a guest house, an in-law residence, staff quarters, or a private office, and it is photographed in its own section of the gallery above.
The property sits inside a gated equestrian community with miles of private riding trails running through the ridge. Buyers planning specific equestrian improvements should confirm requirements with the association and Napa County during due diligence.
A covered wraparound porch with its own fireplace faces Lake Berryessa. Beyond it the grounds include a private swimming pool, a hot tub, a bocce court, a fire pit, and a full outdoor kitchen with BBQ, sink and beer taps alongside a covered dining area and lounge.
Yes. A full Matterport 3D walkthrough of the estate is available directly on this page — you can move through every room, the great room and kitchen, the primary suite, and the outdoor living areas at your own pace, from anywhere. For out-of-area and international buyers it is the closest thing to standing in the house before you fly in.
