Udayagiri Caves are wonderful piece of Jain Archetecture near Vidisha, Bhopal.
From Bus stand the auto guy will ask you Rs 150/- for to and fro journey.
I went there in midafternoon in the month of May.
Temperature must have been 42 degrees
Go through three pieces of photos
I have included the wonderful lying image of Lord Vishnu inside a cave
