History
The ground beneath Solage has been prized for its geothermal properties since the earliest days of Calistoga. Sam Brannan, the entrepreneur and promoter who gave the town its name in 1859, envisioned the geothermal mineral springs at the northern tip of Napa Valley as the foundation for a California resort to rival Saratoga Springs, New York — a comparison embedded in the name itself, a telescoping of "California's Saratoga." The springs drew visitors throughout the latter half of the nineteenth century, and by the time California's wine industry began its modern ascent, Calistoga's thermal landscape had already been drawing health and pleasure seekers for more than a hundred years.
Solage opened in 2007 on 22 acres of Calistoga grounds that carried that long tradition forward into the language of contemporary resort design. The property was conceived as a wellness destination at scale — not a single spa tacked onto a hotel, but an entire resort organized around the idea of restoration, with the volcanic ash mud bath as its defining ritual. Spa Solage's signature mudslide treatment draws on the same geothermal mineral water that Brannan's Victorian visitors sought, reformulated for modern sensibility.
The resort's architecture departs from the stone-and-barrel-wood vocabulary that dominates Napa Valley. Low-slung wooden cottages with vaulted ceilings spread across the property in a vernacular more coastal California than wine country, giving Solage a lighter, more open character than many of its competitors. Solbar, the resort's indoor-outdoor restaurant, has built a following for its farm-to-table seasonal menu and its position as a gathering place for the broader Calistoga community rather than a hotel dining room closed off from it.
Solage joined the Auberge Resorts Collection as part of Auberge's broader expansion into Northern California's hospitality landscape. It holds AAA Four Diamond recognition and occupies an unusual position within the Napa Valley luxury market: where many of the valley's prestige properties lead with wine and gastronomy, Solage leads with the land itself — with heat, mineral, and the ancient thermal character of the ground on which it stands.
The setting
Solage sits at 755 Silverado Trail North in Calistoga, the geothermal spa town at the northern tip of Napa Valley that Sam Brannan developed as a hot-springs resort in 1862. Framed by the Palisades Mountains and amid a cluster of landmark luxury properties, the 22-acre resort occupies the Calistoga AVA's volcanic-soil wine country. Bothe-Napa Valley State Park is nineteen minutes away, Castello di Amorosa twenty-three, and Tank Garage Winery twenty-seven. Downtown Calistoga's Lincoln Avenue — tasting rooms, boutiques, and historic mud-bath spas — is walkable, positioning Solage as the natural choice for guests who seek geothermal wellness, Calistoga AVA viticulture, and the relaxed sophistication of Napa's storied northern spa capital. 7.6 miles from Robert Louis Stevenson State Park.
