Looking down over daffodil-covered slopes of Castle Rock, the esplanade behind, towards Princes Street and the New Town is one of the joys of spring in Edinburgh. A small group of people are walking through the fields of colour. A train can be seen through the trees, having left Waverley Station. Buses and a tram carry passengers along Princes Street. Looking north along Frederick Street the blue waters of the Firth of Forth are visible.
