Since this was a 2 day trip, we didn't get the chance to explore Belum caves. However if you are planning to go there, it's advisable to keep one day extra just for the caves so that the trip doesn't feel hectic. We touched NH 44 by 4 and reached Bangalore by 6 pm. Although hectic, the trip turned out to be really good due to the well laid out roads and an amazing destination.
How to reach:
Gandikota is about 280 km from Bangalore and if traveling during day time, you can take the NH 44 till Lepakshi, switch to State highway 87 till Kadiri and then SH 28 till Gandikota.
There's only one option of staying at Gandikota and that is Haritha resort. So if you are not making an advance booking, it's advisable to go Proddatur for the night stay. Gandikota is about 50 km from Proddatur.
Things to be careful of:
The route mentioned has a lot of unmarked speed bumps and no fuel pumps for 100 km sections. So it's advisable to traverse through it only during daylight hours .
Accommodation should be booked before going so as to avoid any hassle on reaching the place.
