Penon de Velez de la Gomera, Spain, is the shortest border in the world. At only 85 meters, this border is constantly being monitored by helicopters and the army to ensure security between the two countries. This international border is a Spanish exclave and rocky bound island located in the western Mediterranean Sea.

Penon de Velez de la Gomera is connected to the Moroccan’s sandy isthmus shore. Moreover, it is also tied to a smaller islet to the east called La Isleta. On the Moroccan side, the international border is attached to the town of Badis. Therefore, the place’s other name is Hajar Badis.


San Marino/Italy border 

weirdest international borders San Marino

San Marino is a landlocked country within Italy, and the country is completely independent. This microstate of 60 square kilometers is the fifth smallest country in the world. Small but mighty!

Surrounded by Italy, the international borders between the two are the regions of Emilia Romagna and Marche. Uniquely, you can still drive an Italian rental vehicle in San Marino. This is because the country is a part of the Schengen area, so it would not be an issue.


Slovakia/Austria/Hungary border

Have you ever thought of standing in three different countries at once? The good news is, you can do it! In these three European countries, a triangular picnic table lies in a tripoint between the international borders of Austria, Slovakia, and Hungary.

Moreover, you can also have lunch on this triangular picnic table. Just move where you are sitting to ‘travel’ between each country one by one. Such an exciting experience, isn’t it? However, you might have an audience while eating. This is because international borders are controlled by the countries’ armies. 

Nepal/China Border

The international borders between Nepal and China are probably one of the highest international borders in the world.

Moreover, a scenic route named Friendship Highway links the Chinese/Nepalese border to the capital of Tibet, Lhasa. This highway leads to the Sino-Nepal Friendship Bridge, connecting Zhangmu, China, and Kodari, Nepal.

Vatican City

As a historical hub, the country attracts millions of visitors every year. You can go inside Vatican City without needing to perform border control. In fact, you probably will not even notice that you are no longer in Italy as you entered Vatican City territory.

Lesotho/South Africa

Have you ever imagined a building that is located exactly between two different nations? Haskell Free Library and Opera is an example of that. The building lies exactly on the international borders of the U.S. state of Vermont and the Province of Quebec, Canada.

You can actually visit this building both from the U.S. and Canada. However, there is one thing that you should notice. You cannot go to the opposite country’s door while visiting. If you exit into the other country, you will get into trouble. So, please bear this in mind!

Spain/Portugal

Do you know that you can actually cross the border between Spain and Portugal by zipline? This adrenaline-rush vehicle mode is what makes the international border interesting. However, you can only do this from Spain to Portugal, not the other way around. Still, this is an exciting thing to do!

This transportation mode, called Limitezero, is located in Sanlúcar de Guadiana, Spain. The facility provides visitors with a unique journey crossing over the Guadiana River. In fact, this is the first cross-border zipline in the world!

Haiti/Dominican Republic

There is a long wall bordering Haiti and the Dominican Republic. However, the interesting part of this international border is not its wall. What makes the international borders between Haiti and the Dominican Republic is simply because of its landscape.

On the Haitian side, the deforestation practices are clearly seen. On the contrary, the forest is still green and fresh in the Dominican Republic. Even more, the contrastive view between the two countries is even clearly seen not only from a bird-eye view but also from space.


All of Australia

You already know that Australia is a continent or a country surrounded by oceans. That is what makes the international border in Australia interesting. The borders of this country are only sea borders, adjacent to the oceans in Indonesia, Timor Leste, Papua New Guinea, New Zealand, and other Pacific Countries.

The DMZ, North Korea/South Korea
