I am going to Germany (at Hannover) next month, with a Schengen visa (multiple entry) for Germany for a week. But I want to explore Paris for a while as CDG airport is not so far from many tourist places, such as the Eiffel Tower, etc. I am planning to book tickets via Air France having a layover over 10 hrs at CDG Airport so that I can have some time to explore and catch the next flight to Hannover after that. So my questions are...
Q1. Do I need a transit visa for my purpose? or what kind of transit visa do I need?
Q2. If I only want to be at CDG Airport during layover time to explore the airport area only, then also do I need a transit visa?
