The Spa at Napa River Inn

The Spa at Napa River Inn sits inside the Napa River Inn on 5th Street in downtown Napa, open to both hotel guests and outside visitors with a day pass. Facilities include a thermal pool circuit, sauna, steam room and cold plunge, alongside a treatment menu of massages, facials, exfoliations and specialty body work using organic, wild-harvested and hand-milled products from local producers, including a grape-seed-based Napa Valley Organics line.

Beyond standard spa treatments, the property runs a med spa arm with Dr. Walter Tom, MD, offering Botox, fillers, Fraxel and other facial rejuvenation services for guests interested in more clinical options alongside traditional bodywork.

Access is adults-only, with a minimum age of 18 for most treatments; some services may carry additional restrictions worth confirming at booking. The spa is open daily from 8am to 8pm, and reservations are recommended, particularly during busy periods. Spa packages can be customized from the treatment menu, and gift certificates are available for those booking on someone else's behalf. This is a mid-to-upper price tier spa (tier 3), fitting its downtown Napa Valley setting among wine-country hotels and tasting rooms.

Worth knowing before booking: cancellations typically need 36 hours' notice to avoid a fee, and group or event bookings may follow a different policy, so it's best to check specifics when scheduling. The combination of thermal circuit facilities and clinical med spa services makes this a spa that can serve both a relaxed day-pass visit and a more treatment-focused appointment in the same location.
