Starting on the Isle of Lewis in the Outer Hebrides, witness the 5,000-year-old standing stones of Callanish, traditional Scottish blackhouses, and cut peat with a modern crofter.

Venture to England's South Coast, as we dive with sharks, explore the battlements of Drake's Island, uncover the origins of Scouts, and discover fossils on the Isle of Wight.
