West Highland Railway

The Glenfinnan viaduct, which stretches 1,250 feet through the Scottish Highlands, with trains chugging across the Finnan River at a height of 100 feet, is probably most known for its appearance in "Harry Potter."

The majestic views on Scotland's most famous railway route transport you straight into the Highlands without even leaving the carriage, making this one of the world's most spectacular train trips. It starts in Glasgow and heads northwest, ending in Mallaig, where you may catch a ferry to the Isle of Skye.

Along the way, you'll pass through Loch Lomond and the Trossachs National Park (yep, you'll chug alongside the loch), past Ben Nevis, and across Rannoch Moor, where the line is "floated" above the peat bogs, with red deer and stags often your closest neighbors for miles.
