Six Senses is set to open a wellness resort in Napa County in 2026. Named after the natural thermal Aetna Springs discovered in the 1870s, the original resort thrived until the 1970s as a natural spa destination, with Aetna Mineral Water also sold throughout the American West.
Located a two-hour drive from San Francisco, Six Senses Napa Valley will welcome guests to the western edge of a 3,000-acre estate. Architecture firm Olson Kundig will work alongside California-based Architectural Resources Group and Weller Development Partners to ensure the structures are preserved and adapted for the new hotel. The existing structures will be preserved, and the landscape regenerated to bring back the beauty and functionality of the natural mineral springs, with a focus on native planting.
The resort will have95 rooms and suites, including 10 tent-style structures, with interiors designed by 1508 London. There will also be 16 branded residences, and an exclusive lounge. One of the four F&B outlets will be an open-plan dining hall animated by long communal tables and cozy corners among totem poles. The Well will offer an informal and open-air space to celebrate the history of Aetna Springs with mineral water bottling and distilling. To dilute all that water will be the region’s best wines, including Napa’s Cabernets. The Juice & Brew Bar will offer homemade and herbal tonics and tinctures, detox juices, artisanal and draft beers, and original and classic cocktails.
The historic mineral springs will be revived with indoor and outdoor thermal experiences and bathing. Restored greenery will ensure pockets of privacy for a secluded post-swim lounge on the surrounding decks. Indoor bathing facilities will incorporate local herbs and essential oils into hot and cold therapies.
The Alchemy Bar is the place to blend spa scrubs and soaps to suit the season and mood, using natural ingredients picked from the resort’s organic garden.
Programming will include yoga, meditation, mindfulness, visiting practitioners and various treatments and therapies, all inspired by nature. Personalized longevity programs will work on the mind-gut-skin connection, fusing scientific advances in neuroscience with ancient wisdom.
The investment group, comprising Weller Development Partners, Pegasus Capital Advisors and IHG Hotels & Resorts, will work with expert partners in sustainability to restore the recreational green spaces, vineyards, and agricultural activities supporting the resort. The water bottling program will tap into the natural springs and offset operational water requirements. Practices such as re-wilding zones and the use of sustainable design and materials will help the resort achieve LEED certification.
