Mid-century modernism is far from the only style in Palm Springs. La Serena Villas is the latest transformation of a 1933-vintage Spanish-style hotel, and while its new owners have thoroughly updated it for the boutique-hotel era, they’ve kept its inspiration intact — you’d be hard pressed to find a lovelier example of colonial-contemporary architecture and design.

Just north of San Diego, a few miles inland from Del Mar, is the Rancho Valencia Resort, a quiet retreat in a private canyon near the affluent community of Rancho Santa Fe. Accommodations are scattered about the grounds, hacienda-style, with one or two suites to each casita. Suites feature cathedral ceilings, hand-painted tiles, fireplaces, and plenty of space.

With 358 rooms and suites and a spa that could be conservatively described as “massive” (42,000 square feet), the Ritz-Carlton Bacara verges on luxury overkill. The style is inevitably Spanish, all whitewash and tile roofs, and the buildings hug the ground, sprawled like a village, which lends a surprising degree of intimacy to such a palatial hotel.

Ojai’s longest-standing hotel (established 1919) has been restored to its former glory and reopened as a 50-room boutique. El Roblar’s was a sensitive restoration, retaining the property’s Spanish Revival architecture, including the Mission-style entry archway and the lobby’s stone fireplace, and added in design elements that pay homage to the Ojai Valley.

This Rat Pack–era institution is Spanish Revival through and through, and while it’s been brought up to date, the atmosphere is still steeped in Old Hollywood romance. Rooms are elegant above all, with plenty of historical detail alongside the modern conveniences; and they’re all refreshingly unique, owing to the twists and turns of the existing floor plan.

The building that contains Drift Santa Barbara is a beautifully renovated example of Twenties Spanish architecture, in keeping with the picturesque local style. All the more surprising, then, that its stylish interiors are so beautifully minimalist, a masterful blend of simple clean lines and warm, richly textured organic materials.

This 1920s estate began its life as a Spanish/Mediterranean Revival mansion for a now-forgotten silent-film star. Later it was a girls’ school, later still a convent. When interior designer Dana Hollister bought it, it became something arguably more unique: part film set, event venue, dream house for Hollister herself, and finally, unforgettably stylish hotel.

Some mid-century Palm Springs hotels have thoroughly reinvented themselves for the boutique-hotel era, but not Villa Royale. Make no mistake, it’s been renovated, expanded, and brought quite up to the latest luxury-boutique standard, but the Spanish-style architecture is still very much intact, updated with street art–inspired murals and bold contemporary graphics.

Don’t let the word ‘inn’ fool you—the Ojai Valley Inn isn’t some rustic little bed and breakfast, but a secluded and spectacular resort, a 1920s Spanish Colonial revival-style compound sprawling across several hundred acres of a wooded mountain valley that’s long been a favorite getaway for refugees from the bright lights of Hollywood.

California’s wine country is full of architectural homages to Europe, and this one, erected in the 1980s by salt heiress Mary Tilden Morton, is a hacienda-style tribute to the Spanish countryside, built from reclaimed 19th-century timber. As a luxury boutique hotel, Rancho Caymus Inn remains somewhat intimate, weighing in at a mere 26 rooms and suites.
