- Belum Caves in Andhra Pradesh is the second longest cave in the Indian subcontinent open to public. The cave is second natural cave only after Krem Liat Prah caves in Meghalaya.
- Belum caves are renowned for their speleothem structures, such as stalactite and stalagmite formations.
- With long passages, narrow galleries, and spacious tanks filled with fresh water, this cave was formed over the course of tens of thousands of years by the constant flow of underground water from the now-disappeared river Chitravathi.
- The caves hold immense historical significance as there are several indications that these were occupied by Jain and Buddhist monks many centuries ago
