There are so many things to do in Edinburgh. You can either travel by foot or by tour bus. We chose to travel by foot armed with our checklist. I will let you in a secret, I like to google the spots and I rely heavily on Wikipedia to tell me the places of interest in certain area. :P
It is located in Central Edinburgh. This is a very good spot over-looking the New Town.

Princess Street Gardens:
One of the prettiest gardens that I've been. The photo below is a perfect photo spot. You have the Edinburgh Castle in the background.
Here's the map for Princess Street Gardens - http://www.edinburgh-royalmile.com/princes-st.gnds/princesst-gnds-map.html
This is probably the number 1 tourist spot in Edinburgh. They had a massive queue when we went.
