Great photos on your blog Clive! I visited this place about 10 years ago and was amazed by these formations… Though some need a bit of artistic licence to look like a seal with a ball hahahaha 🙂
The Torcas de los Palancares are also in that area… 30 sinkholes caused by the underwater erosion of the limestone, and if you visit in the winter they may be full of water. The sinkholes are over 80 million years old and are a part of the Palancares y Tierra Muerta Natural Monument.
