What: A palatial seaside complex at the year-old Terranea resort, with its own posh pool and café. Separate outdoor men's and women's decks have ice-cold plunge baths, hot tubs, fire pits, and awesome ocean views. Treatments are of the New Age variety.
The look: A spanking-new building in Spanish colonial revival style, with elaborate tilework and giant hearths. Sunlight-drenched waiting areas open to private patios.
Who goes: Actors on hiatus (including Lost cast members), stay-at-home moms, East Coast families.
The treatment: The 90-minute Oil and Water scrub involves a blissful algae oil basting and a full-body sea salt exfoliation that leaves you feeling as ravishing as a mermaid, without the scales.
P.S.: The Ocean Prelude is applied in a sublime suite with an ocean view (massages, $165).
