The Gruta dos Caldeirões, located about 18 km from Taguatinga in southeastern Tocantins, is a key adventure tourism destination that offers visitors a chance to connect with pristine natural environments in the Serras Gerais region. The cave features internal rivers and stunning rock formations that create a captivating yet potentially hazardous experience if visitors are not vigilant.

The cave's intricate structure is divided into different levels, forming a three-story labyrinth. The lowest level includes a river with a smooth, dark bedrock, resembling a 'marble pool' which enhances the cave’s exotic allure. Navigation to the upper levels requires both effort and caution, as there are risks of falling or temporarily getting lost. In addition to the subterranean maze, a vivid emerald-green river emerges from the cave’s entrance, leading to two waterfalls with clean, refreshing waters that are perfect for swimming after exploring the cave.

Tourist advisor Andreia Bernardes highlights that while the cave's beauty is enticing, visitors should take the necessary precautions to enjoy the adventure safely. The appeal of the Gruta dos Caldeirões extends beyond its immediate beauty, as it provides a unique experience in nature that aligns with the interests of adventure seekers and eco-tourists alike, merging thrilling exploration with the enjoyment of stunning natural landscapes.
