ONE OF THE MUST-SEE STOPS HERE! Our Park has 12 large holes in the ground known as Caves (Furnas in Portuguese), Sinkholes or Vertical Caves. This is because we are part of the outcrop area of the Furnas Formation, with sedimentary rocks of coastal marine origin whose age is approximately 400 million years.
Currently, there are about 50 Caves in the Campos Gerais region, most of which are shallow or underdeveloped. However, those in our Park have unique characteristics. Some are dry, some are deep, some are narrower and others are larger.
Those with water at their bases reveal an underground interconnection by a water table, called the Furnas Aquifer. So, the lakes have the same level of height on the surface and reflect the rich vegetation of the place.
We offer complete tourist infrastructure for visitors to sight the two deepest Caves in Paraná (Caves 1 and 2), which boast a depth of up to 100 meters. The huge walls of Cave 1, covered with rich vegetation, serve as shelter for thousands of biscutate swifts (Streptoprocne biscutata) that every day offer a spectacle of nature to visitors with their flocks at sunset and at dawn.
Bring your camera or cell phone to record the best photos, repellent to keep insects off and sunscreen to protect yourself from the sun's rays.
