 There are plans to encourage more tourists to visit the Zapata area , particularly from Europe , and if the United States allows its citizens to visit Cuba in the future this could further increase the effects of ecotourism . This might have a dangerous impact on the wetland , but Cuba 's Tourism Minister , Manuel Marrero , and Pablo Bouza , the director of the Ciénaga de Zapata National Park , both said that the increase in tourism would be sustainable .
