There are more than one story about this waterfalls but one legend says that this waterfalls appeared after the identical twins, Maria and Cristina were bathing in the Agus River. Maria, the younger twin, was carried by the current. Cristina tried to save her sister, but the current was so strong that both of them drowned. People were amazed when a beautiful twin waterfalls came about from were the sisters perished. And everyone called it Maria Cristina. This legendary waterfalls is the outlet of Lake Lanao through Agus River. It is sometimes called the "twin falls" as the flow is separated by a rock at the brink of the waterfall. The 320 - feet (98 meters) high waterfalls is also the primary source of electric power for the city's industries, being harnessed by the National Power Corporation - Agus Hydroelectric Power Plants.

The Maria Cristina falls are majestic. We were lucky to have a guided tour from the hydro plant company, since the park is at this moment closed for tourists. However it will eventually open again soon. You walk (or drive) along the Agus river, where the two last hydroplants are located. There is a bat cave where you can see and hear hundreds of bats on the hunt for insects. In front there are the waterfalls - usually twin falls - falling down into the fast running Agus river. There seemed to be rafting and zip lining before which is cancelled right now, but I really would like to go there again.
