What Color Is the Water?
Perdido Key's water is a canvas of emerald, turquoise, and jade, shifting hues as the light changes through the day. On sunny afternoons, the Gulf sparkles like a jewel, with quartz-white sand beneath acting as a natural reflector.
It's the kind of sight that keeps photographers snapping, painters sketching, and beachgoers pausing simply to soak in the view.
