The north end is home to some especially picturesque beaches, but this one is where smugglers landed with their wares centuries ago and where pirates were hung to warn others. The soft white sands sit against brilliant blue waters in a myriad of shades, while beach cafes sell famous Herm ice cream.

Lundy Island

Lundy Island, Devon (Nearby Hotels)

There is nothing between this three-mile-long, half-mile-wide island that lies off the coast of Devon, England and America in the Bristol Channel. A truly unspoiled isle, Lundy is home to less than 20 inhabitants, but offers incredibly dramatic scenery and a fascinating array of wildlife. It’s also rich in history, with a number of interesting places to visit. Lundy’s lighthouse is the highest in England, and though it was decommissioned, it is open to visitors who can climb the steep and precarious spiral staircase to the top, from which the entire island, and possibly puffins, seals, dolphins, and occasionally, a basking shark, can be viewed. It’s undisturbed by vehicle traffic, phone reception is sketchy, and the only pub on the island, Marisco Tavern, bans laptops and smartphones, making it an ideal place to truly escape the hustle and bustle.
