Wadden Sea coast, Friesland, Netherlands

If you've ever dreamed of walking on water or something close to it, the Wadden Sea is the place for you. Tracing over 480 kilometres along the coast of the Netherlands, Germany and Denmark, this UNESCO World Heritage Site offers a unique landscape of tidal flats and wetlands. In fact, it is the world's largest unbroken intertidal zone—the area that is underwater at high tide and exposed at low tide—of sand and mud flats. The area is also a playground for aquatic species such as houting, brown trout and white-beaked dolphins, and it's a home or resting spot for species of birds like waders and herons.
