The perfect place to catch this view is from a vaporetto approaching Venice from the lagoon --- the most magical way to arrive from the airport; turismovenezia.it
17. Electrical storm, Tornado Alley, United States
From thunder to lightning to tornadoes, you can see it all by joining a storm-chasing crew in Tornado Alley, the area between the Rocky and Appalachian Mountains where 25% of America's "significant" tornadoes occur, according to the National Atlas by the US government.
The best time to catch a glimpse of one is from May to June.
Wannabe stormers can join the seven-day tour hosted by Storm Chasing Adventure Tours. Be prepared for a rough and tough tour --- they may drive 500 miles a day in the chase.
Seven-day tour costs US$2,400; stormchasing.com
18. Taj Mahal, India
It may be the most clichéd image in the world, but visitors still gasp the moment they first set eyes on the world's most famous shrine to love.
Best enjoyed at sunset, when there are not too many tourists around to spoil the spell, or over a drink from a distance at Amarvilas, a luxury hotel overlooking the magnificent white marble mausoleum.
Built by Shah Jehan in the 17th century in memory of his third wife Mumtaz, the Taj Mahal forms part of the Golden Triangle, which is the classic first tour for visitors new to India.
Intrepid Travel offers seven days from Delhi, taking in the pink city of Jaipur as well as the Taj Mahal, from $805; intrepidtravel.com
19. Pristine beaches, Seychelles
Clean, secluded and easy to skip because it takes some effort to get here, the beaches of the Seychelles are the benchmarks against which others must be judged.
From Grand Anse and Anse Source d'Argent on La Dique island, to Beau Vallon on Mahe to the entire Bird Island -- the Seychelles' beaches bring bright sands, copious wildlife and possibly the best beach vacation you'll ever have.
They even won first and fourth spot in our list of the world's best 100 beaches.
Seychelles' relaxed visa policy (you don't need one) is only slightly offset by the need to have pre-booked accommodation. Flights head to Seychelles International Airport from various major hubs including Johannesburg, Nairobi, Dubai and Doha.
20. Northern Lights, Scandinavia
This astronomical phenomenon is best seen in winter from northern Scandinavia --- but there are never any guarantees, which makes the magic moments when they do appear all the more special.
A great place to keep watch is from the sheltered coastal waters of western Norway, whose coves are free of artificial light.
Travel there on Hurtigruten, the country's national coastal steamer, and enjoy inspirational fjord views by daylight.

21. Yosemite peaks, California
Not just any old mountains, Half Dome, Sentinel and El Capitan have been immortalized by landscape photographer Ansel Adams. The view catches in the throat of first-time visitors who trace the route taken by the Gold Rush settlers who discovered this breathtaking land of pine forests and soaring granite peaks around 1850.
It's mandatory to stay within the National Park boundaries to breathe the pine-scented air, absorb the grandeur and hike in peace after the day-trippers have left. While simple lodge cabins are good value, the magnificent 1920's Ahwahnee Hotel overlooking Half Dome is worth the splurge (rooms around $450 per night); yosemite.com
22. Lake District lakes, England
