Five days on the Scottish Highlands

I wanted to do this trip from a good couple of years, but as Scotland is not that far from here, just about an hour of flight from Dublin to Edinburgh, I always skipped this trip in favour to other places, like Amsterdam, Copenhagen or Iceland. And also because visiting these capitals it takes only a weekend, so no need to use days off from work, while Iceland has to be well planned and would be stupid if you go there for the first time only for a few days. But last Christmas myself and my lovely girlfriend decided to do this trip finally, so we booked the flight, and by using the bank holiday in March (St. Patrick), we did a 5 days trip in the Scottish Highlands.
