Definitely the highlight of Edinburgh (although slightly out of town). It is wonderful. It is Jupiter Artland.
A sense of humour & so many fabulous site specific pieces from contemporary art greats. We visited on a glorious day. The Andy Goldsworthy stone wall that weaves through the trees made the walk from the carpark to the start of tour as enjoyable as the stroll through the park! Coffee and treats are served through an airstream and another Andy Goldsworthy site specific mud-caked wall installation sits oh-so-casually on the cafe wall. Very cool.
