There are a lot of things that make a spa great -- the range of services, the quality of the masseuses, the number of features. That's all well and good, and you can find the lists of our favorite spas in each city on our Hotel Spas page. But what makes a spa great isn't necessarily what makes a spa sexy. These spas, are, in a nutshell, stunning. These spas beckon you; just looking at the photos makes you calmer. So sit back, relax, and enjoy. No stress, no hassle -- which is just what you need. First up, Terranea Resort. No other Los Angeles spa can compete with the Terranea's size or features, precisely because, well, it's not really in L.A. -- it's in Ranchos Palos Verdes, a ruggedly beautiful coastal enclave at L.A. County's southwestern tip. The three serene private treatment rooms, called VIP suites, are themed after the elements; the earth suite has a redwood sauna and shower, the fire suite has a fireplace, and the water suite (pictured) has a copper tub and views of the Pacific.
