Edinburgh is the city of festivals, and in August there are several of them. One of the largest is the Edinburgh Festival Fringe (The Fringe). The events on offer are almost unlimited. We arrived at the tail end, but still found lots of interesting things to to.
You can for instance take a daytime walking-tour of both the Old Town and the New Town and learn quite a lot in the process.
Or you can take a night-time literary pub tour in the same areas, guided by two professional (and very entertaining) professional actors.
This of course involves visiting some local pubs ...
If you want something a wee bit different, you can enjoy Scottish folk music in a small, but packed cellar salon bar.
And there is always whisky-tasting - guided by those who know how (The photo is NOT from where the tasting was located). Somehow i forgot to take any there.
