Which famous fight happened here?

This remarkable 800ft mountain waterfall is the site of a famous fictional showdown. Just outside Meiringen, Switzerland, the Reichenbach Falls are the backdrop for The Final Problem, the 1893 Sherlock Holmes story where, on a precipice near the falls (which in the 19th century gushed with far more power than our recent image shows), the genius detective enters a death duel with the criminal Professor Moriarty. In the end, both men plummet to their presumable doom.

Though the action in The Final Problem was set on 4 May, it's 22 May which is celebrated as Sherlock Holmes Day, as that is author Arthur Conan Doyle's birthday. The doctor-turned-writer created Holmes with A Study in Scarlet in 1887 and intended to kill off his famous protagonist with The Final Problem, to move on with his literary life. But pressure from Doyle's anguished, sleuth-starved public led him to 'resurrect' Holmes (but not Moriarty) a decade later with The Adventure of the Empty House. In all, Doyle wrote four novels and more than 50 short stories starring Holmes over four decades. They've gone on to inspire other books, plays, radio dramas, movies, TV shows, comics and video games featuring the super-sleuth.

Where's this amazing waterfall?

Sunwapta Falls is one of several waterfalls in Jasper National Park in Alberta, Canada, formed by hanging valleys. These valleys were created 8,000 years ago when glacier ice receded. Sunwapta Falls is actually a pair of waterfalls, a lower and upper one. The water comes from the Athabasca Glacier and there is more of it in the summer than the winter, due to seasonal glacial melting. Jasper National Park is the largest national park in the Canadian Rockies, with more than 4,000 square miles for camping, hiking, water sports and other activities. Wildlife in the park includes elk, grizzly bears, moose, bighorn sheep and caribou.

A view of Sutjeska National Park, Bosnia and Herzegovina

Bears, boars, wolves and Balkan chamois roam through a dramatic and sweeping landscape of ancient forests and jagged limestone mountains. There’s plenty of room for them to wander: Sutjeska covers some 43,000 acres in southern Bosnia and Herzegovina. Established in 1962, it’s the country’s oldest national park and protects Perućica, one of Europe’s few remaining primeval forests. (A 207-ft Norway spruce tree here is said to be the world’s tallest.)

Sutjeska Park’s creation was not only inspired by environmental concerns, but historic ones as well. A decisive battle of WWII was fought here in 1943, in which a small Yugoslav army defeated the much larger German invading force. Standing in the park is an enormous stone monument commemorating the fight.
