Top 10 Enclaves and Exclaves

Metal_Treasure
An enclave is an entire country or part of a country completely surrounded by the territory of another country. The only way to access the territory of an enclave is by crossing the territory of the surrounding country because the enclave has no land connection to the rest of the main country territory.

An exclave is "a piece of land which is politically attached to a larger piece but not physically coterminous (having the same borders) with it because of surrounding foreign territory." - wiki

Many entities are both enclaves and exclaves. But there are enclaves that are not exclaves and exclaves that are not enclaves. Examples:
Three sovereign countries are enclaves but not exclaves: Lesotho, San Marino and Vatican City.
Exclaves which are not enclaves: Nakhichivan Autonomous Republic, and some smaller entities.

3 Baarle-Hertog Baarle-Hertog

Luckly, both of these countries are in the European Union so you can freely travel between them, both also use Euros and both speak the same language (Dutch) - christangrant

In the image you see the border - if you have dinner on the Dutch side (Nl, left) and your restaurant closes earlier, you just have to move to the Belgian side (B, right), which is a step away, and finish your dinner. - Metal_Treasure

Baarle-Hertog is a Flemish municipality of Belgium, much of which consists of a number of small Belgian exclaves in the Netherlands.
Read this and try to imagine how these bits of land look like - you can cross 4 international borders in just 4 minutes:
"Baarle-Hertog is noted for its complicated borders with Baarle-Nassau, Netherlands. In total it consists of 24 separate parcels of land. The main division of Baarle-Hertog is Zondereigen (named after its main hamlet), located north of the Belgian town of Merksplas. In addition there are twenty Belgian exclaves in the Netherlands and three other sections on the Dutch-Belgian border. There are also seven Dutch exclaves within the Belgian exclaves (i.e., counter-exclaves). Six of these Dutch enclaves are located within the largest Belgian enclave, and a seventh in the second-largest Belgian enclave. An eighth Dutch exclave is located nearby Ginhoven." - wiki

5 Naxcivan / Nakhchivan Autonomous Republic Naxcivan / Nakhchivan Autonomous Republic

Naxcivan aka Nakhchivan is a pretty big chunk of Azerbaijan in Armenia. To access this exclave from Azerbaijan you have to cross either Armenia or Iran (both routes are too close to the dangerous region of Nagorno-Karabakh). - Metal_Treasure

6 Campione d’Italia Campione d’Italia

It's a very beautiful Italian municipality entirely surrounded by Switzerland (that's a "true" enclave and exclave of Italy).
How did this happen? In 1798, the canton of Ticino chose to become part of the Swiss Confederation, but this municipality chose to remain part of Lombardy, Italy. This decision was confirmed by a referendum in 1814. Later Campione d’Italia tried to join Switzerland but the Swiss refused, not wanting to be drawn into Italian disputes.
So how Italian is Campione d’Italia today? It has a Swiss dialing code, Swiss emergency responders, and uses the Swiss currency - Swiss Franc. - Metal_Treasure

10 Angle Inlet / Northwest Angle Angle Inlet / Northwest Angle

A mapping error during the 1783 Treaty of Paris left a chunk of US territory in present day Canada, then British territory. The map they used misrepresented the lake’s location and the border drawn between the US and what was then British territory, created this oddity. - Metal_Treasure
