Borra Caves

This is a name on the list for tourists visiting Andhra Pradesh, never to mention the neighboring Araku Valley. Formed naturally, these caves are enormous and scary. If you look up the ceiling, you tend to get this uneasy feeling of going into a huge pile of rubble that might collapse any moment. And yet, an easy head count of 100 a day visit the place, clap and shout inside the caves. It is said to have been in existence for ages - first discovered by a British geologist in eighteen hundreds. For extensive details, google for Borra Caves and feel lucky to see a Wiki page opening.
The APTDC has improved the place. It has a restaurant, waiting lounge and snacks shops for visitors comfort. Once inside the cave you can find pavements and stairs to go around the caves. There are certain places that are considered risky and are out-of-bounds for the tourists. However, like in any other place, you find daring tourists climbing the caves and venturing into risky zones. The caves stink of staleness caused by lack of sun-light and bat-droppings in certain places. Since the caves are located in a hill and rest of the area is a forest, you find it common to see a lot of monkeys. Do not feed them and do not tease them. However, you find yourself teased by them if you are carrying any food items. They allow cameras and camcorders inside the caves but they charge you for that (10 rupees for a still camera and 100 for a camcorder).
If you are returning to Vizag on road from Borra, you can stop-by for a snack at APTDC restaurant/cottages near Tyda railway station.
