With depths reaching 700 feet and a length of more than 20 miles, Loch Ness provides plenty of hiding places for its legendary monster. Should you tire of searching for Nessie, this scenic section of the Scottish Highlands also has charming villages like Drumnadrochit and Fort Augustus, open-air Shakespearean productions, multiple golf courses and medieval Urquhart Castle. Wildlife of the non-mythological variety and ancient Caledonian pine forests can be found in the Glen Affric nature reserve.

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.

Maybe your local zoo has lions, leopards, zebras or elephants. Maybe they even have wildebeest. But we bet they don't have 1.3 million wildebeest—never mind 1.3 million wildebeest in migration, with predators in hot pursuit. It's one of the most awesome sights in nature, and you can see it at Masai Mara in southwestern Kenya.

The Maasai call the plains of Serengeti National Park "the place where the land moves on forever"—so prepare to be astonished by its vastness. And here, you can witness the famous Serengeti annual migration, the largest and longest overland migration on earth.
