All the sites are part of the state of North Karnataka. the road route was
Sholapur - Bijapur -Badami - pattadakal - Aihole - Hampi - Lakkundi - Hubli
Some pre visit preparation is essential. While the internet provides good information, booklets brought out by ASI especially its World Heritage series gives good insight into the history and background of the monuments and can easily be carried for further reference.
And of course some history books will help. I am currently reading "India: A history" by John Keay. This is particulary inteesting for those readers from overseas who would like to understand the history of India and its civilisation from 4000 B.C. tothe end of the 20th Century
