Yesterday on the way to Siccar Point, we were persuaded to purchase the “historic Scotland Explorer Pass” at Tantallon Castle. It gets us into lots of castles for one price, like the Gold Pass for our National Parks. So, today we will explore Edinburgh Castle, a short walk from our hotel. 

This is Tantallon Castle from yesterday. We wandered all over, inside and out. Bass Island, a steep mound in the firth and visible from the castle is the home of 20,000 nesting pairs of gannets. The top of the island is bright white, and from the highest point we could climb in the castle, we could see many white birds swimming on the water surface.
