This is probably the top attraction in Edinburgh and it's easy to see why. This castle has such a long and fascinating history, and the current incarnation of it is quite a beautiful sight. There is so much to see at the castle that you'll want to spend at least half a day looking around. I also highly recommend the free tours as you get a lot of facts that you wouldn't know otherwise.
It's hard to miss Edinburgh castle when in Edinburgh -- but it is worth taking a full half day for a nice leisurely tour around. Highlights are the prisons of war exhibition and "Honours of Scotland" -- Scotland's crown jewels (try to go to this early to avoid the lines and tour groups). The views of Edinburgh are great -- try to go on a sunny day for good photo ops. We also took a great shot of out 7 year old inside Mons Meg -- one of the worlds oldest cannons.
