Palawan, Philippines. Over twenty years and many expeditions have allowed us to make dream explorations in an incredible place. The Puerto Princesa Underground River has dug colossal tunnels into the mountain: it crosses it for miles and then flows into the South China Sea with a large estuary. In the darkness of this cave live hundreds of thousands of bats and swallows, which contribute to creating a unique ecosystem in the world. Also thanks to our discoveries, this cave has been included among the new seven natural wonders of the planet.

 

 
Finally all this work sees the light in a great book. With narrative cut, diaries, stories and beautiful images, the volume illustrates the history of exploration, geological and biological research on the cave and the karst area.
 

 
The book went to press just these days. We will present a preview at the international speleological meeting, which will be held in Casola Valsenio (RA) from 1 to 4 November where it will also be possible to buy it at our stand.
 

 
Also on those dates will be available the number 23 and 24 (number speciele dedicated to Giovanni Badino) of Kur, our historical magazine.
 
We are waiting for you!
