Everyone loves a good view. Observation experiences are a type of specialty attraction growing in popularity around the world. After all, if you're going to build the tallest building in the land, you might as well sell tickets to the top.
This growth of these attractions is driven primarily by a combination of increasing urbanization, technology improvements that allow for higher building heights, faster and more reliable mechanical systems, and the realization by developers and operators that they can provide serious money, according to the Themed Entertainment Association, which produces an annual report on global attractions.
Some of the sites on this list are iconic, historic, must-see experiences that have been around for decades or longer, others are repurposed broadcast towers, multi-use buildings, Ferris wheels or stomach-dropping observation decks with bars, restaurants and plenty of Instagram ops. Most are fascinating examples of engineering, architecture, and innovation. All have epic views of some of the most famous cities in the world. Above, the shadow of the Burj Khalifa in Dubai, the world's tallest building, is seen from the observation deck.
Based on the Themed Entertainment Association's report on 2018 attendance of attractions around the globe, these are the most popular observation experiences in the world.

1. Tokyo Skytree, Tokyo
- 2018 Attendance: 6.4 million
This broadcasting and observation tower is 634 meters, or 2,080 feet, tall.
It is the tallest structure in Japan and the second tallest in the world at the time of its completion.
The Skytree has two decks, the lower Tembo Deck, at 350 meters and spanning three levels, and the 450-meter high Tembo Gallery, pictured here, a sloping spiral ramp that gains height as it circles the tower. The Skytree has a large shopping complex with an aquarium at its base.

2. Eiffel Tower, Paris
- 2018 Attendance: 6.2 million
Probably one of the most recognized structures in the world, the 324-meter Eiffel Tower, named for the engineer who designed and built it, was constructed as the entrance to the 1889 World's Fair.
The Eiffel Tower has three levels for visitors, with restaurants on the first and second levels. Though hardly the tallest structure in the world these days, it held that title for 41 years until the Chrysler Building in New York City was completed in 1930. It still offers stunning views of Paris, though a view of Paris seems incomplete without the iconic tower in it. At night, every hour on the hour, it lights up and sparkles for five minutes.

3. London Eye, London
- 2018 Attendance: 3.9 million
Europe's tallest cantilevered observation wheel, the Coca-Cola (KO - Get Report) London Eye is also the most popular paid tourist attraction in the U.K. When it opened in 2000, it was the world's tallest Ferris wheel, at 443 feet high. (It has since been bested by China, Singapore, and Las Vegas.)
The only higher view in London is the Shard, a 95-story skyscraper, which you can also visit, but hey, it's not a Ferris wheel. Above, people view the Thames from one of the London Eye's capsules.

The Empire State Building stood as the world's tallest building for nearly 40 years when it was completed, until the World Trade Center was built in 1970. After the Sept. 11 attacks in 2001, it reclaimed the title as the tallest building in New York until the new One World Trade Center was finished in 2012.

5. Tokyo Tower, Tokyo
- 2018 Attendance: 2.92 million
Another communications and observation tower in Tokyo, this is the second-tallest structure in Japan at 332.9 meters high. The structure is an Eiffel Tower-inspired lattice tower that is painted white and international orange to comply with air safety regulations.
The Tokyo Tower has 600 steps to the top. Because the staircase is in the open air, it is sometimes closed in bad weather. According to the Tokyo Tower site, most kindergarteners make the 600 steps in 15 minutes, and it encourages "out-of-shape fathers, mothers on diets, children's groups" to climb the stairs as a challenge. Calorie-burning charts are posted along the climb.
6. Tokyo City View, Tokyo
- 2018 Attendance: 2.9 million
