Advice for shooting Outdoors/Landscape in Scotland?

Hey all, I am going out to Scotland for New Years, and I am excited to take my camera to and take pictures. I currently am primarily a street photographer, and I live in the 35mm range, so I am pretty covered with the shooting in Edinburgh and Glasgow, but I will also be heading out into the Highlands and into the Isle of Sky and how almost no experience with out door/landscape, so I was just wondering what focal length ranges I should be looking at?

Thanks
