The journey followed this route.. I tried to give small explanation against each place barring Hyderabad -
Mantralayam (Raghavendra Swami temple),
Hampi -Ruins of Vijayanagara Empire, Virupaksha Peetham,
Srikari and Krishna with Lakshmi
Prem, Hampi Swamiji and Lalitha
Ihole (2nd to 4th Centureis), Pattadakkal (5th - 6 centuries), Badami (8th - 9th centuries) (These places are of great importance with respect to the starting and flourishing sculpture of South India),

You can see here Lord Vishnu in Vamana avatara in the cave dedicated to Lord Vishnu. In case of Badami rock cut temples it takes a week to complete all the 4 caves if we were to see and appreciate its grander in its true sense.
Gokarnam - one of the 12 jyothirlingas. When we went there Koti Rudrayagam is being performed there. You can see standing Ganapati there who putdown the Aatmalingam there which he took from Raavana.
Mrudeshwar -- On the seashore is awesome to watch
Udipi -- which houses Lord Krishna. How many ever times you watch you can not feel satiated.
Sringeri -- No need to say anything about this place. It seems that every year once the river Tunga overflows. It happened this time when we were there.
Horanadu -- The temple of Annapurnewari. Unforgettable glimpses of the mother. I took a rare photo of Sangeetha Saraswati there.

You can see different birds representing Saptaswaras
Dharmasthala -- Manjunatha Swami temple
Kukke Subrahmanya.
Halebeedu and Belur -- These 2 places best represent the peak of South Indian Sculpture.
Though we could not cover in detail because of a whirl wind tour, we enjoyed a lot even though it was raining heavily through out.
