Waterfalls are a stunning work of nature that tend to attract large crowds to come and see them. Many of the largest also happen to fall on borders, making them easy stops for people traveling through multiple countries. While there are a countless number of these natural pieces, here are five waterfalls around the world that are particularly massive.

1. Niagara Falls
On the border between the United States and Canada, Niagara Falls is actually made up of a few different waterfalls. The aptly named Canadian Falls sits on the Canadian side of the border while the just-as-aptly named American Falls sits on the American half. There are also the Bridal Veil Falls, which were once connected to the American Falls, but were split off by the natural forces of the Niagara River over time. The water roaring down the falls comes from the Great Lakes, and both the American and Canadian governments have taken control of the flow in order to slow erosion, as well as divert some of that energy for electric power.

2. Iguazu Falls
Iguazu Falls lies on the border between Argentina and Brazil, with lovely national parks to wander through on either side. Though not considered to be the largest falls in the world, they are taller than Niagara Falls and wider than Victoria Falls. The parks on each side have unique wildlife from jaguars to toucans, providing even more to see past the 275 waterfalls and the rainbows sprouting from them.

3. Rhine Falls
While Rhine Falls sits very close to the German border, Switzerland gets complete claim over Europe’s largest waterfall. There are other European waterfalls that are longer or have higher drops, but Rhine Falls are often dubbed the largest for their width and the massive volume of water flowing through each second. The name of the falls is derived from the Rhine River that provides the vast amounts of water flowing through.

4. Detian Falls
Detian Falls, also known as Ban-Gioc Falls, is on the border between Vietnam and China, and is considered to be the largest waterfall in Asia. It’s most recognizable by the lush-surrounding greenery and towering peaks rising from behind it. While this is an incredibly popular spot for both people of both nations, foreigners don’t wildly visit it despite it’s beauty. The ideal time to visit the falls is from May to July, as the water level won’t be too high or too low, creating the best view of the falls.

5. Victoria Falls
Hailed as the largest falls in the world, Victoria Falls also acts as one of the most popular destinations for travelers in all of Africa The waterfalls sit on the border of Zambia and Zimbabwe, and while most people opt to go through Zimbabwe to see it, Zambia is a great and underrated option. These falls are so striking they’re considered to be one of the original seven natural wonders of the world. The ideal time to visit would be as the sun sets during a full moon when a “moonbow”, a rainbow caused by moonlight, appears among the falls for a sight like no other.
