Guided tours take many forms. There are custom-made Scotland tours with your own tour guide, with the tour often built round a specific theme, for example genealogy or fine dining. There are whole programmes of guided tours, usually starting and ending in the cities, which allow small groups of visitors more than a glimpse of the scenic Highland areas of Scotland. These tours can be one day or longer. A number of tour guides also offer special interest tours, such as birdwatching or walking.
