Cachoeira Boca da Onça, located on the Rio Salobra within the municipality of Bodoquena in Mato Grosso do Sul, is the tallest waterfall in the state, plunging 156 meters through lush riparian vegetation.

The site sits on Fazenda Boca da Onça, roughly 55 km from Bonito, and also features a canyon overlook that provides panoramic views of the surrounding Serra da Bodoquena landscape.

The waterfall is the centerpiece of a broader ecotourism area that encompasses at least eight cascades along a trail following the Rio Salobra's ciliary forest. Several of these drops have natural swimming pools suitable for bathing.

The property also hosts what is described as Brazil's highest rappel platform, a 90-meter descent set within the Rio Salobra canyon.

Trails of varying lengths connect the different waterfalls and points of interest, including the formations known as Buraco do Macaco and Janela para o Céu. The terrain is steep and can be slippery, making sturdy footwear advisable.
