Bosnia and Herzegovina

• Number of visitors per year: 1,307,319 (in 2017)

The nearly-landlocked country of Bosnia and Herzegovina (the country has just 20 kilometres of coast along the Adriatic Sea) was first settled by the Slavic people beginning in the 6th century. Over the centuries, the country has evolved to be a multicultural oasis perfect for travellers looking for something new on their next adventure. Following a crushing civil war in the 1990s, the country has rebuilt and become a tourist destination well worth the visit. Raft down turquoise rivers, be inspired by ancient architecture, and immerse yourself in the country’s east-meets-west vibe. Travellers interested in visiting lesser-visited countries should hurry to Bosnia and Herzegovina, though – the country is projected to have the third-highest tourism growth rate in the world until 2020.

Liechtenstein

• Number of visitors per year: 80,900 (in 2017)

At only 160 square kilometres, the principality of Liechtenstein is filled to the brim with Medieval charm, stunning views of the Swiss Alps, and traces of ancient nobility. The first farming settlements in Liechtenstein were founded around 5300 BCE, making this tiny country between Switzerland and Austria more than just a novelty; it’s a culturally-rich destination where travellers will find stunning cliff-side castles, charming villages, and untouched nature. If that wasn’t good enough, the country also has one of the world’s lowest crime rates – there hasn’t been a murder since 1997 – and you’ll find plenty of peace and quiet here. In fact, there are local rules against “holding noisy festivities” during Liechtenstein’s official lunch break from 12 to 1:30pm.

While these countries are small, they’re loaded with huge adventures! Whether you want to spend your next vacation enjoying delicious food in San Marino or trying your luck in Monaco’s casinos, these destinations are not to be missed.
