7. HAVASU FALLS

Nestled deep in the remote Havasupai Indian Reservation (a side canyon of the world famous Grand Canyon in Northern Arizona), this special year-round waterfall is one of the most beautifully situated waterfalls in the country. Adding to its scenic allure are the blue-green waters of Havasu Creek, the travertine stalactites and dams surrounding the falls, and the red-rock scenery that makes the Grand Canyon possibly the nation's most visited National Park. Putting this unique waterfall on the list was a no-brainer.

6. MULTNOMAH FALLS

One of the most iconic waterfalls in the US, this is the star attraction of the famous Columbia River Gorge, which itself boasts numerous waterfalls - many of which are serious waterfalls themselves. But this 620ft year-round waterfall with a concrete arched bridge over its lower drop as well as a historic lodge fronting it always draws millions of visitors each year. And after our visit to this waterfall, we don't blame them!

5. VERNAL FALL AND NEVADA FALLS

Collectively comprising the lowest steps of the Giant Stairway, this pair of giant waterfalls in Yosemite National Park, California could've easily stood on this Top 10 List separately. But we figured you ought to see both falls in one go so we put them together here. Vernal Fall has a classic rectangular shape and is said to plunge some 307ft. Nevada Falls has an unusual trapezoidal horsetail shape as the Merced River plunges then slides (some 594ft in total) its way down towards Vernal Fall.

4.BRIDALVEIL FALL

While there are other similarly-sized waterfalls (or bigger) in the country, I'm partial to this 620ft year-rounder because its position frames Yosemite Valley (arguably the most beautiful valley in the world) opposite the imposing El Capitan. Ever heard of "The Gates of Yosemite Valley"? Indeed, this waterfall is part of the landscape imagery made famous by Ansel Adams and seen by just about every visitor thereafter (perhaps making it cliche to some). But on its own merits (ignoring the cliche aspect), there's no question it's one of the most beautifully situated waterfalls ever. Heck, the sight of the incomparable valley when we leave the Wawona Tunnel and head into the valley during spring still leaves a lump in my throat every time.

3.LOWER FALLS (OF THE YELLOWSTONE RIVER)

Including this over 300ft waterfall amongst America's Top 10 was compulsory. After all, its impossibly-scenic location at the head of the Grand Canyon of the Yellowstone River makes this the must-see attraction of Yellowstone National Park, Wyoming. That's saying something considering the park is more famous for predictable geysers and an abundance of wildlife that some consider America's version of the Serengeti.

2. YOSEMITE FALLS

This 2425ft waterfall is one of the tallest in the world and widely considered the crown jewel of Yosemite National Park's plethora of cliff-diving waterfalls. The falls is enjoyable from numerous spots where you can drive to as well as hike to. The only catch with this beauty is that it dries up by mid to late Summer as it runs through its massive winter snowpack very quickly thanks to its relatively bare, unforgiving granite drainage. Nonetheless, if it can induce superlatives from the likes of Ansel Adams, John Muir, Thomas Ayres, Francois Matthes, James Hutchings, and more, there's a good chance it can do the same to you, too!

1. NIAGARA FALLS

The Granddaddy of the waterfalls in the United States, it easily surpasses all others in the country in terms of sheer power, size, popularity, and more. Shared between Western New York in the USA and Southeastern Ontario in Canada, bring your passport and experience this world famous attraction from both sides as well as the plethora of activities on offer here. We consider this waterfall to be one of the World's Big Three so it easily occupies the top spot amongst America's Top 10. If you could only see one waterfall in the country, besides crying, make sure not to miss this one!

4. Climate

Climate: mostly temperate, but tropical in Hawaii and Florida, arctic in Alaska, semiarid in the great plains west of the Mississippi River, and arid in the Great Basin of the southwest; low winter temperatures in the northwest are ameliorated occasionally in January and February by warm chinook winds from the eastern slopes of the Rocky Mountains. USA can be divided into six climate regions, excluding Alaska, Hawaii and outlying territories. The climate varies considerably between different regions.

Northwest Pacific:

(Includes states like Oregon and Washington to the crest of the Cascade Mountains)

This is the perhaps the wettest part of the country. There are scattered rain showers all year round. Temperatures are mild averaging around 40 degree F. (32.2 degree C). The summer months are pleasantly warmer but never too hot. You can see fogs along the coast during the warmer weather but the fog is less dense during mid-day.

Warm clothes: You will need extra warm clothes for winters like leather jackets, thermal jackets, warm inners, leather gloves etc.

Mid/South Pacific Rockies:

(Includes states like California, Idaho, Montana, Wyoming, Colorado, Utah and Nevada)

These states have generally dry and delightful summers.

California has excellent weather all the year round, with the northern part of the state somewhat cooler (quiet chilly in the winter but seldom freezing). There are very few places in California that experience snow, and the state is known for its nice weather. Mostly all the cities have tolerable winters.

The winter months in the other states like Montana, Idaho and Wyoming can be very cold, with temperatures dropping well below 0 degree F. Colorado, Utah and Nevada are known for their excellent skiing.

Warm clothes: For California you will need warm clothes for winters. For the rest of the Mid-South Pacific region you will need warmer apparel.

Midwest

(Includes states like Dakotas, Kansas, Illinois, Iowa, Minnesota, Wisconsin, Michigan, and Indiana)

This region is moderately dry. Precipitation occurs mainly in late spring and early summer. Summers are pleasant but winter time can be harsh, with lots of snow and heavy chilly winds. Extremes within the Midwest can drop down to -50 degree F.

Warm clothes: You will need extra warm clothes for winters like leather jackets, thermal jackets, warm inners, leather gloves etc.
