Get off the tourist drag and onto the gin trail: see the New Town through gin-tinted spectacles with gin liqueur cocktails, G&T toasted marshmallows, gin-cured salmon and a Highland gin and tonic in a cool cocktail bar on this fab two-hour walking homage to gin. Walk past the site of Edinburgh's largest gin distillery on the Water of Leith " built in 1740 " and learn a little more about this juniper flavoured spirit which at one time surpassed whisky sales.
