Tanggu, a busy seaport that has shunned tourism for industry, is an unlikely location for this jovial amusement park. Yet, come summer and it jumps with humanity. Located about 30 minutes south of Tianjin on the Bohai Gulf, the park harbors the largest manmade beaches and waterslides in China. Constant blaring music piped in on the park's speakers adds to the park's carefree atmosphere. Waterslides cost an additional amount.
