3 Best Sights in Argyll and the Isles, Scotland

Seemingly out of place in this near-wilderness setting, Bonawe is a fascinating relic from the dawn of Britain's Industrial Revolution. In the mid-18th century, Argyll's virgin forests attracted ironmasters from England, where such valuable fuel sources were harder to find. Business boomed when wars with France boosted demand for pig iron and cannonballs, and in its heyday Bonawe employed up to 600 unskilled local wood gatherers and skilled southern foundrymen.

Like the lair of a classic James Bond villain, this triumph of 20th-century British technology lurks deep within a vast man-made cavern. Hidden 3,000 feet beneath the slopes of Ben Cruachan, the colossal water-driven turbines of this subterranean power station, completed in 1965, supply clean energy to much of Scotland. The ½-mile bus ride from the surface to the generating hall is a surreal experience, made all the more so by the subtropical plants that thrive under artificial light in the warm, humid atmosphere.

Gorgeous tweed, plaid, and tartan clothing, wraps, and throws---woven at this historic mill and dyed in subtle, traditional tones---are sold here.
