Orvakal Rock Garden, or Oravakallu Rock Garden, is a 1000 acre  
park with igneous rock formations between pools of water. It is  
located on NH-18 highway, outside the village of Orvakal, about 20  
kilometres (12 mi) from Kurnool, Andhra Pradesh, southern India.  
There is a restaurant, boating, a cave museum and picnic areas on  
the site.  

The park, with hiking paths that snake up a hill, was developed by the  
Andhra Pradesh Tourism Development Corporation (APTDC). The  
content of the rocks is quartz and silica, a raw material for the glass  
industry. Several companies have petitioned for the ability to mine the  
area, which raises ecological concerns.  

The park has been a site for film production, which has resulted in  
another ecological concern due to plaster of paris remnants left at the  
park after the movies were completed.
