Chinese dubbed it "red carpet beach", tourists often name it "the sea of red", and in reality, this is a field of seepweed or seablite. It grows on 130 square kilometre area, and this patch of land is a part of world's largest and best-protected wetlands around Shuangtaizi River mouth, outside of the city of Panjin. Besides the coloured weeds, the wetlands boast 260 species of birds and 400 species of other wildlife.
The coloured plant is the major tourist attraction. Scientifically, it's called Sueda salsa. This type of grass is the only one thriving in highly alkaline soils. The weed starts growing in April, then its colour is pale crimson. The main display of deep red starts in autumn, this is when the weed is already mature.
If you love the red colour, and even if not really, this is a unique and extraordinary experience to walk among nothing but red. Where else would you do this? Well, perhaps in the dreams.
As this is a state-level natural reserve, tourists access is limited to a certain territory. The best time to enjoy mature red-hued weeds is September throughout to early November. By the end of the November, they are not as impressive, and in winter die at all, until it's reborn next spring.
