Julia Bradbury's first walking foray into Scotland has a very distinct flavour to it - whisky! The Speyside Way is one of Scotland's great walking routes, and between the villages of Craigellachie and Ballindaloch it follows the route of the railway that once served a remote area and a world-famous drinks industry.

The backstreets of Weymouth seem an unlikely spot to explore railway history, but Julia discovers there was once a short railway that ran south from Weymouth and across the unique coastal features of Chesil Beach and Portland. The walk is the ideal platform for learning about the history of Portland Harbour and the tied isle's most famous export, Portland stone.

Julia Bradbury faces an epic walk in more ways than one. Not only is this the longest and arguably most dramatic walk yet, but it passes through the unruly territory of Scottish clans and Rob Roy. The Highlands were a place to be wary of, until the railway arrived.
