You can start your journey by visiting shore temple. There are a lot of monuments and temple built during the Pallava dynasty, so you can see many beautiful art inside the caves. And then there is the famous Krishna’s Butterball! I tried to push that rock and believe me even science can’t prove why that rock is not moving. Light house are an amazing place to have a good picture and with a view of sea it’s just beautiful. Visit here and just explore the beautiful curvature of stones and caves .
