Look at any world map and the rule seems simple enough: some countries touch the ocean, and some do not. But hidden inside the group of countries with no coastline is an even rarer, stranger category. A handful of nations are so deeply buried inside a continent that every single one of their neighbors is also landlocked. To reach salt water from their territory, you cannot simply cross one border and arrive at a beach. You must pass through at least two foreign countries first. Geographers call these places doubly landlocked, and astonishingly, in a world of roughly two hundred nations, only two of them exist: Liechtenstein and Uzbekistan.
What "Doubly Landlocked" Actually Means
A landlocked country is one with no direct access to an ocean or to a sea connected to the ocean. There are more than forty such countries, from Switzerland to Bolivia to Mongolia. A doubly landlocked country raises the bar one level higher: not only does it lack a coastline, but so does every country it borders. The consequence is geometric rather than political. Starting from inside a doubly landlocked nation, the shortest possible journey to the sea requires crossing a minimum of two international frontiers, because the first country you enter is guaranteed to be coastless as well.
It is worth being precise about what counts. A "sea" here means a body of water with a navigable connection to the open ocean. This is why the Caspian Sea, despite its name, does not rescue its neighbors from landlocked status: it is an enclosed inland lake with no natural outlet to the world ocean. That technicality matters enormously, as we will see with Uzbekistan.
Why the Phenomenon Is So Rare
Being doubly landlocked requires a very particular arrangement of borders. First, a country must already be landlocked, which only about one in five nations is. Then it must avoid bordering any coastal neighbor whatsoever. Most landlocked countries fail this second test almost immediately, because the more borders a country has, the more likely at least one neighbor reaches the sea. Mongolia, for instance, borders only Russia and China, but both of those giants have long coastlines, so Mongolia is "merely" landlocked. The condition is essentially a quirk of where political lines happen to fall, and small shifts in those lines can switch a country in or out of the category overnight.
Liechtenstein: A Tiny Alpine Survivor
The first doubly landlocked country is the principality of Liechtenstein, a microstate of about 160 square kilometers tucked into the Alps between Switzerland and Austria. Both of those neighbors are themselves landlocked, which is what gives Liechtenstein its rare distinction. The nearest coastline, on the Adriatic, lies well over a couple of hundred kilometers away across foreign territory.
What makes Liechtenstein especially interesting is that it was not always doubly landlocked. For much of its history, neighboring Austria-Hungary controlled a stretch of Adriatic coastline. When that empire dissolved after the First World War and Austria emerged as a smaller, coastless republic, Liechtenstein quietly inherited its peculiar geographic title. The change happened not because Liechtenstein moved an inch, but because the map around it was redrawn.
Despite its isolation from the sea, Liechtenstein is anything but cut off. It sits in the wealthy heart of Europe, shares a customs union and a currency with Switzerland, and participates in the European Economic Area. Goods move in and out with minimal friction, and the principality boasts one of the highest standards of living on Earth. Here, double landlocking is a fascinating piece of trivia rather than an economic burden.
Uzbekistan: The Heavyweight of the Pair
The second doubly landlocked country could hardly be more different. Uzbekistan, in Central Asia, is home to more than thirty-five million people and stretches across a vast expanse of desert, steppe, and irrigated farmland. It borders five countries: Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan, and Turkmenistan. Every single one of them is landlocked, which seals Uzbekistan's status.
Uzbekistan is the larger of the two doubly landlocked nations by an enormous margin, and it is also the more revealing case for why the Caspian Sea's classification matters. Kazakhstan and Turkmenistan both touch the Caspian, but because that body is an enclosed lake rather than an arm of the ocean, those neighbors remain landlocked, and Uzbekistan stays doubly so. To reach genuinely open water, Uzbek goods must travel a long way, typically toward distant ports far beyond its immediate neighbors, crossing multiple borders along the way.
Unlike Liechtenstein, Uzbekistan feels the practical weight of its geography. Exports such as cotton, gold, natural gas, and other commodities face long overland routes, multiple customs regimes, and the added cost and delay of every border crossing. Landlocked economies generally face higher trade costs than coastal ones, and a doubly landlocked giant like Uzbekistan sits at the sharp end of that disadvantage.
A Tale of Two Very Different Situations
The two members of this exclusive club illustrate that the same geographic label can mean wildly different things in practice. Consider the contrasts:
- Size: Liechtenstein is one of the smallest countries in the world, while Uzbekistan spans hundreds of thousands of square kilometers.
- Population: Liechtenstein has tens of thousands of residents; Uzbekistan has tens of millions.
- Neighbors: Liechtenstein borders just two countries; Uzbekistan borders five.
- Distance to the sea: Liechtenstein's nearest coast is a few hundred kilometers off, while Uzbekistan's open-water access is far more remote and route-dependent.
- Economic impact: For Liechtenstein it is a curiosity, smoothed over by deep European integration; for Uzbekistan it is a real factor shaping trade and transport.
Common Misconceptions
The topic invites a few persistent misunderstandings. The most common is the assumption that there must be more than two such countries somewhere in Africa or South America. It is a reasonable guess, given how many landlocked nations those continents contain, but the precise border arrangement simply never lines up to produce a third doubly landlocked state.
Another misconception is that doubly landlocked countries are necessarily poor or remote. Liechtenstein single-handedly dismantles that idea, ranking among the most prosperous places on the planet. A third confusion involves the Caspian Sea: people assume Uzbekistan's Caspian-touching neighbors must give it indirect sea access, but because the Caspian is an enclosed lake, it does not change anything. Geography here follows strict definitions, not intuition.
Could the List Ever Change?
The membership of this club is remarkably stable, but not frozen forever. History shows it can shift: Liechtenstein only joined after Austria lost its coast, and for a brief period in the early 1990s, before the breakup of certain neighboring states settled into its current form, the lineup of Central Asian borders was in flux. The list could change again if a neighbor of either country somehow gained a coastline, if new states emerged from existing borders, or if territories were redrawn. None of these scenarios appears likely in the near future, so for now the count holds firm at exactly two.

Frequently Asked Questions
How many doubly landlocked countries are there?
There are exactly two: Liechtenstein in Central Europe and Uzbekistan in Central Asia. Both are surrounded entirely by other landlocked countries, so reaching the sea from either requires crossing at least two international borders.
Why is Uzbekistan doubly landlocked when two of its neighbors touch the Caspian Sea?
The Caspian Sea is technically the world's largest enclosed lake, with no natural navigable connection to the open ocean. Because it does not link to a sea, the countries bordering it, including Uzbekistan's neighbors Kazakhstan and Turkmenistan, are still considered landlocked. That keeps Uzbekistan doubly landlocked.
Has a country ever become doubly landlocked because of changing borders?
Yes. Liechtenstein became doubly landlocked after the First World War, when the former Austro-Hungarian Empire lost its Adriatic coastline and Austria emerged as a landlocked republic. Liechtenstein's own borders did not move; the surrounding map changed around it.
What is the difference between landlocked and doubly landlocked?
A landlocked country simply has no coastline of its own, but it may border one or more coastal countries. A doubly landlocked country has no coastline and every neighbor is also landlocked, so the shortest route to the sea always passes through at least two foreign countries.
Conclusion
Double landlocking is one of those geographic oddities that sounds like it should be common until you actually trace the borders. It requires a precise nesting of coastless countries inside coastless countries, and the planet's political map only manages to produce it twice. Liechtenstein and Uzbekistan, one a tiny Alpine principality and the other a sprawling Central Asian nation, share almost nothing except this rare distinction, and the way it shapes their lives could hardly be more different. Together they remind us that the lines we draw on maps carry real consequences, and that geography still holds surprises hiding in plain sight.
