You can easily plan on your own and don't require to book any package. If you are planning to night stay only at Bangalore, then consider the places which can be done in a day tour. (1) Nandi Hills - Chikkaballapur
(2) Savandurga Hill (3) Lepakshi
(4) Mysore - Ranganathittu
(5) Chunchi falls (6) Bangalore city (2 days)
(7) Shivanasamudra If you are interested to do night stay at locations other than Bangalore then you have plenty of options. You can visit these places in between your 1 week trip for a day or two. (1) Hogennakkal falls (in Tamil Nadu, 180 km from Bangalore)
(2) Chikmagalur (3) Co-org
(4) Hampi
(5) Kabini and Bandipur if you are interested in wildlife and forests. Luxury Buses are all these destinations from Bangalore along with trains. Also you can hire private cabs from any agency or from online travel booking websites. Hope this helps....:)
