This is the commanding height of Edinburgh, and you can overlook the panoramic view of Edinburgh from the castle. The castle on the cliff is spectacular, and there is only a slope for entry and exit.

There are several rows of cannons beside the city wall, demonstrating the castle's once supreme royal power.
