THE ST MAGNUS FESTIVAL in Orkney (www.stmagnusfestival.com ) takes centre stage on the festival merry-go-round this month, but there is no question where the biggest crowd will gather. That will be in the tiny village of Dores on Loch Ness, when 20,000 are expected to descend for the Loch Ness Monster (www.rockness.co.uk ) event, featuring Fatboy Slim and Skye-born Mylo on the bill.
