This is a good half-way point area between the two main cities of Edinburgh and Glasgow onwards to the Scottish highlands.
Areas around Glencoe, Fort William and Glenfinnan.
Accommodation on the island of Skye. If you are visiting in the summer months, I strongly suggest you pre-book your stay as soon as possible. Rooms on the island book up quickly. The main town on the island is Portree.
Area around Aviemore and Cairngorm National Park
Car hire locations in the highlands. In my opinion, you will need a car to fully experience the beauty of the area. I always suggest buying fuel prior to travelling over to the western islands as it is cheaper on the mainland.
