Getting naked in public is generally frowned upon, but at Spa Castle, it's just part of the experience. Once you get past the awkwardness of shucking your clothes in front of complete strangers of all stripes, you'll easily melt into the relaxing experience that is Dallas' biggest Korean spa. Once you've soaked (totally naked) in the tension-soothing hot tubs and showered, you can put your clothes back on and head out into the spa's large outdoor water park. Or, you know, you can just stay in the gender-segregated nude areas and enjoy a day relaxing in your birthday suit. At this place, no one is going to judge you for wanting to stay in the buff.
