It is the perfect combination of adrenaline, physical effort, and the reward of diving into crystal-clear waters in some of the beautiful places that nature has carved.

Get your breath and your camera ready, because we will guide you through every detail of what is, without a doubt, one of the most impressive and Instagrammable places in all of Brazilian ecotourism.

The Grand Setting: The Salobra River Canyon

Boca da Onça Ecotour is located in the municipality of Bodoquena, neighboring Bonito, on a farm that is home to one of the most impressive geographic features in the region: the Salobra River canyon. Unlike the calm waters found on many floating tours, the Salobra is a wilder river that descends through the Serra da Bodoquena, cutting through limestone rock walls and creating a sequence of more than ten waterfalls.

It is within this epic-scale setting, where vegetation clings bravely to the rocks and wildlife hides within the dense forest, that the entire adventure unfolds. The grandeur of the canyon provides the perfect stage for the attractions that make Boca da Onça a truly unique experience.

The Adventure Trail

The main tour of the complex is the Boca da Onça Trail. It is important to set expectations: this is one of the longest and most demanding trails in the region, with approximately 4 km in length and a staircase of more than 800 steps that seriously challenges your legs on the way back up. However, every step and every drop of sweat is generously rewarded.

The trail is done in small groups, always accompanied by a specialized guide who sets the pace and enriches the journey with valuable information about the local fauna, flora, and geology. The path is well structured, with support points along the way, yet it maintains a rustic feel, connecting visitors directly with the Cerrado and Atlantic Forest environments.

Throughout the route, the sound of the Salobra River provides a constant soundtrack, and with every turn, a new surprise is revealed. The tour includes stops at several waterfalls and natural pools for swimming, essential for cooling down and restoring energy.

Memorable Stops Along the Trail:

Monkey Hole (Buraco do Macaco): A natural pool with green-tinted waters where it is possible to swim and pass beneath a rock to emerge on the other side. A fun and refreshing experience.

• Otter Pool (Poço da Lontra): A peaceful spot for a relaxing swim, surrounded by lush forest.

• Window to the Sky (Janela para o Céu): A natural infinity-edge pool that opens up to the vastness of the Salobra River Canyon, inviting pure contemplation.

• Boca da Onça Beach: A small river beach that forms at the base of the main waterfall. From here, you get the first complete and striking view of the 156-meter giant.

Boca da Onça Waterfall

After walking part of the trail, you finally reach it: Boca da Onça Waterfall. With its 156-meter free fall, it is the largest waterfall in Mato Grosso do Sul and the most iconic image of the tour. The power of the falling water, the mist that wets your face even from a distance, and the thunderous sound create a moment of pure awe and respect for nature.

The name “Boca da Onça” comes from a rock formation at the waterfall’s source that, according to longtime residents, resembles the face of a jaguar. The natural pool that forms at its base is not suitable for swimming due to the strength of the water, but a wooden deck allows visitors to get very close to feel its energy and take spectacular photos. It is, without a doubt, one of the most beautiful waterfalls in Brazil and a scene that stays etched in your memory.

The Largest Platform Rappelling in Brazil

For adrenaline junkies, Boca da Onça offers an unmatched experience: the largest platform rappelling descent in Brazil. The activity is optional and can be done without the need to complete the full trail.

The adventure begins on a metal platform that extends 34 meters over the Salobra River canyon, delivering a breathtaking view. From there, it is a 90-meter vertical descent alongside towering rock walls, with the valley opening up beneath your feet. The sensation of floating in midair, surrounded by such a grand landscape, is indescribable.

The entire operation is carried out with maximum safety by a highly qualified team of instructors using top-of-the-line equipment. No previous experience is required to participate. At the end of the rappel, you arrive near Boca da Onça Beach, where you can then join the trail group and enjoy the rest of the tour. It is a rush of emotion that takes your trip to a whole new level.

Top-Tier Infrastructure for Travelers

The Boca da Onça Ecotour farm features one of the best visitor infrastructures in the entire Bonito region. Upon arrival, visitors will find:

Reception and Restaurant: A climate-controlled restaurant serving a delicious lunch typical of Mato Grosso do Sul after the tour, with hot dishes, salads, and regional desserts.

Swimming Pools: Two pools with flowing river water, perfect for relaxing before or after the trail. The canyon views from the pools are a spectacle in themselves.
