Cachoeira da Velha is widely regarded as the largest waterfall in Jalapão, located within the Parque Estadual do Jalapão in Tocantins and fed by the waters of Rio Novo.

The falls span roughly 100 meters in width and drop approximately 15 meters, forming a striking horseshoe shape. The sheer volume and force of the water make it impossible to swim beneath the falls.

Visitors typically view the waterfall from a dedicated overlook platform and boardwalk accessible by car, though a separate hiking trail offers a less-traveled perspective sometimes called the "hidden side."

Just downstream, a small river beach on Rio Novo provides a calm spot to wade in the clear water. The waterfall is considered one of the most iconic natural landmarks in Jalapão and a highlight of any visit to the region.
