In the heart of Calanques National Park, Cassis offers visitors a glimpse of life in a quaint Provencal fishing village. Hop on a sightseeing boat to experience the Cassis Calanques by water, or enjoy the turquoise coastline from a pebble beach. There’s much to explore by foot, too. Admire the pastel-colored houses lining the picturesque harbor, drift into the village’s charming shops and cafes, and take in the scenic views of the French Riviera from the many vantage points along the way.

Make sure to pack your wellies, because Snowdonia National Park is one of the wettest spots in the U.K. Besides being soggy, it’s also pretty impressive. A fairly easy hike takes you to the top of Yr Wyddfa, the highest peak in Wales (topping any peaks in England, too), where peregrine falcons nest in the jagged cliffs. The park also has the largest lake in Wales, Llyn Tegid. It has its own Loch Ness-style monster—called Teggie, of course—though some figure it’s just an unusually large pike. This Snowdonia’s wonders can also be found on a smaller scale. Keep an eye out for the Snowdon beetle, which has rainbow stripes down its back.

Highland Perthshire places some of Scotland’s most spectacular scenery within easy reach of both Glasgow and Edinburgh, and Pitlochry is the most geared-up base from which to enjoy it. It’s been a bustling mountain resort since the railways arrived in 1863, and these days manages to be both a cozy favourite for tourists who enjoy browsing in its woolen mills and taking in the repertory of plays at its famous Festival Theatre, and a magnet for adrenalin junkies in search of bungee jumping, canyoning, tubing and white water rafting adventures. Visitors of any age will be intrigued by the Pictish carvings on the huge Dunfallandy stone at nearby Ballinluig and, after a bracing mountain walk or visit to the famous salmon ladder, adults can enjoy a warming dram of malt whiskey after a tour at one of the two local distilleries, Edradour and Blair Athol.

Stratford-upon-Avon is steeped in the history of its most famous resident, William Shakespeare. This Warwickshire country town contains the home where Shakespeare was born, the cottage where Anne Hathaway resided before their marriage and the church where the couple is buried. Need a break from the Bard? The town also boasts Europe's largest butterfly farm.
