Solage Auberge Resorts Collection

Solage is at 755 Silverado Trail in Calistoga, at Napa Valley's northern end, a mile from downtown Calistoga. San Francisco International is about 85 miles and two hours by car; Santa Rosa's Charles M. Schulz airport is roughly 35 minutes. A car is essential this far up-valley.

Yes, at a price. Non-resort guests booking a 60- or 90-minute treatment pay a $50-per-person Bathhouse access fee on top, and massage, facial, or Mudslide bookings carry an additional $35 non-resort fee Monday–Thursday. A separate day pass bundles facility access with a $300 wellness credit, subject to blackout dates around peak periods.

Yes — Spa Solage and the Bathhouse are 18 and over, resort guests included. Calistoga's standard treatment-spa age gate applies here with no exceptions for accompanied teens.

Solage's signature three-part ritual: "the mud," blended to your preference by a mudtender at the Mud Bar and self-applied; "the waters," a geothermal soak; and "the rest," a zero-gravity Soundchair session with headphone sound therapy. It is the luxury remake of Calistoga's traditional mud bath — playful rather than clinical, and not suitable during pregnancy.

Massages run $300–$362 for 60 minutes and $450–$518 for 90, with non-resort guests at the top of each band. Solage does not publish a standalone Mudslide price on the current menu; recent guests report couples sessions above $500. A 20% service charge lands on top of listed prices.

Yes. Spa Solage adds a 20% service charge automatically to treatment prices — the opposite model to Meadowood, where the listed price already contains it. Budget accordingly: a $362 massage bills at $434 before extras.

Yes — $75 per room, per night; no Napa Valley competitor discloses a higher one. The partial offset: valet and self-parking are both complimentary, which is not the norm at this tier.

The core of the spa's 2021 TLEE-designed rebuild: five geothermal pools running from cold plunge to 104°F, fed by wells on the property, plus sauna and steam room. Access comes with treatments (plus the $50 fee for non-resort guests) rather than as an open amenity.

Yes — conspicuously so. Dogs are welcome across the bungalow grounds, and guest reviews consistently name it the valley's easiest luxury stay with a dog. The spa and Bathhouse are the exception.

For the resort, yes; for the spa, no. Families use the pool and bikes comfortably, but the entire spa operation — Bathhouse included — is 18+, so parents trade off supervision time. Couples remain the core guest mix.

December through February, when entry rates fall to the $600s midweek. Harvest (August–October) is peak, with weekend rates from $1,100 to $1,900+. Mud-and-stay packages have historically required two-night minimums; check terms before building a trip around one.

For most guests, yes — it is the thing Solage does that nobody else can, and couples call it more fun than a standard massage. The dissent is worth hearing: a vocal minority calls the self-applied format "do-it-yourself" at a premium price. If you want hands-on pampering end to end, book a massage instead.

Solage sells the modern luxury version — custom-blended mud, geothermal soak, sound therapy, Michelin-starred dinner afterward. Indian Springs sells the historic one: 100% volcanic ash dug on its own property, in concrete tubs used since the Sam Brannan era. Pick Solage for polish and privacy, Indian Springs for authenticity per dollar.
