Contrary to what many initially think, Red Beach in Panjin, China isn’t actually a beach. There’s no vast expanse of sea and sand for it to be considered a beach—just a type of seaweed called Sueda, which starts growing in spring, turns green in summer, and transforms to a beautiful maroon shade in autumn. So the best time to see it (at least, the small portion that’s open to tourists) is during the months of September to November.
