旺比恩山洞—旺比恩喀斯特地貌保护区风貌
The reserve's karst is surrounded by intrusive igneous rocks, which was once covered by volcanic rock. The heat and pressure from these volcanic rocks metamorphosed the 420 mya limestone into coarse crystalline marble. Many of the reserve's caves are highly decorated with four of the largest and most decorative developed for visitors. Figtree Cave, containing large chambers and an active stream canyon, has been developed as a self-guide attraction. These caves are one of the most cavernous karst areas in NSW with over 500 knows caves in an area of less than 600 hectares.
旺比恩保护区的喀斯特地貌四周现在是由侵入型岩浆岩包围着的，而之前则被火山岩覆盖。火山岩的热量与压力使得4.2亿年前形成的石灰岩质变为粗结晶大理石。许多保护区的洞穴内部都进行了精心修饰，其中四个最大最精美的专为游客开发。例如无花果树山洞，内有巨大的洞穴大厅，还有一条流动的谷间溪流，现在已开发为自助游景点。这个洞穴区是新南威尔士州洞穴最密集的喀斯特地区之一，在不到600公顷的土地上有超过500个此类山洞。
