If you’re looking for a great new weekend getaway, try Solage Calistoga, tucked into a former horse pasture at the northernmost end of California’s Napa Valley. At this property – from the people behind Auberge Resorts (Auberge du Soleil, Esperanza) – biking and hiking are king and dress shirts and cocktail dresses so rare you’d think they were illegal.

Solage is intentionally not a formal, Tuscan-inspired wine-country resort. Kids and pets are welcome and – in a style that pays homage to California’s rural roots – guests stay in 89 rooms set within 52 cottages built with wood siding, gable roofs, cross bracing and other exterior farmhouse-inspired architectural touches. Inside, the “studios” are more urbane with open floor plans, concrete floors, pebbled showers and Wi-Fi and iPod docks. Two bicycles per room are provided for outings to wineries and trails.

For recreation, there is a 130-foot thermal pool for body sculpting aqua classes, a children’s pool, a gym, classes in yoga, spin and Pilates and hiking and biking tours to nearby mountain trails guided by the resort’s fitness director.

The resort’s restaurant, Solbar, which opens onto a large outdoor terrace with views of the Palisade and Mayacama mountains, serves locally-produced flavorful spa and comfort food from executive chef Brandon Sharp, an alumnus of Gary Danko, and former chef de partie at The French Laundry.

For indulging on-site, there’s a spa showcasing skin-care guru Kate Somerville’s facials and, in a nod to Calistoga’s heritage as a proto-spa destination, mud treatments and soaking baths fed by the region’s geothermal springs.

Solage aims to be green, too. Room service and cleaning crews arrive on bicycles.
