Lapa Terra Ronca or Caverna Terra Ronca, is a dolomitic limestone cave within the area of Terra Ronca State Park in São Domingos, Brazil. Lapa Terra Ronca houses one of the largest collections of caves and grottoes in South America.

According to momondo:

The Terra Ronca State Park is home to 200 caves, but only two are open to visitors. One of them is Caverna Terra Ronca, a dolomitic limestone cave that, thanks to a collapse thousands of years ago, has been divided in two areas, Terra Ronca I and Terra Ronca II. Both of them are open to the public, though the second part can only be visited with a guide. [source]
