Facilities began to be built as part of the continuing rehabilitation effort starting in 2002. Due to water pollution, the river itself was deemed unsafe for swimming. As an alternative, a nearby pool was constructed for swimmers. Private resorts and hotels have also been built near the area. Since its designation as a national park and its consequent rehabilitation, visitors have steadily increased from 45,563 in 1995 to 83,431 in 2004. This raised the profile of Hinulugang Taktak as the nation's second most popular national park, following the Ninoy Aquino Parks and Wildlife Center. As of 2008, it also recorded the third largest income for any protected area in the Philippines with 11.1 million pesos, following the Ninoy Aquino Parks and Wildlife Center (first) and the Mount Apo Natural Park (second).
