I went to Edinburgh today. It has been years since I was last there. I actually used to stay there when I was really young I was immediately impressed by the place. There are so many things to see, probably too much for just one day.
The Castle is amazing. Arthur's Seat is spectacular. The whole Royal Mile is rich in architecture and history, whether it's Parliament house, The Hub( Tolbooth Church), The Palace of Holyroodhouse or even the new Scottish Parliament building. I loved the views from the Royal Observatory on Calton Hill. It has panoramic views across the city ( very scary views as well because it is really high ). Jacobs Ladder ( think that's its name? ) is really tough on the old legs.
We were going to go to Greyfriar's Churchyard ( GreyFriar's Bobby ), but sadly we ran out of time.
I will definitely go back there again sometime soon. It really is fantastic. I had forgotten how special a place it is
If you have never been to this place. Make a visit. It is now on my wish list for places to stay ( Once I get that WSOP crown

. The central city flat prices are massive)
I also wanted to look at the DH MTB trails on Arthur's seat but didn't have a chance today
