Only by participating in everything in person can you experience the joy of it. I have heard that Chongming Island has the most crabs that other places can not compare with. This Shanghai to Xian tour made me believe the saying. The magnificent scene is really beyond my imagination. Different sizes of crabs' burrows scatter everywhere on the ground, with crabs of all sizes sidles across just beside your feet… While Xian tour would not provide you such a chance due to its geographical conditions.
Covering a total area of 4,500 mu, the Xisha Wetland of Chongming Island is the only one natural wetland that has the Natural tidal phenomenon and a great piece of shoals and forest land in Shanghai area. In recent years, through the projects of bird species introduction, plants configuration variations and the water treatment, Xisha Wetland was rebuilt as a multifunctional wetland ecological demonstration area which assembles science education, scientific research, leisure and sightseeing together on the basis of the original wetland.
The recurrent tide is important condition for the Xisha Wetland to live on. The average time of the flood and ebb tides is 12 hours and 24 minutes. Thanks to the tide, it forms the various landforms in the wetland, including lakes, mud flats, inland rivers, reeds and marshes etc. In addition, the tide also breeds many kinds of animals, such as migrant birds and ghost crabs. In order to make tourists closer to nature, the wetland manager built up a 2-kilometer long wood bridge. Tourists can stroll among the reeds and forests on the bridge.
