Small caves are natural formations found in many parts of the world. They are often referred to as GROTTOES or GROTTOS, which are both terms used to describe small caves. GROTTOES are typically 8 letters long and GROTTOS are 7 letters long. These small caves are usually formed by erosion and can be found in limestone, sandstone, and other sedimentary rocks. They are often home to unique wildlife and can provide a great source of exploration and adventure.
