Santa Clara will forever be remembered as the site of the last battle of the Cuban Revolution, where Ernesto ‘Che’ Guevara led a group of rebels in a mission to derail an armoured train, resulting in the definitive defeat of the Batista regime. And though bullet holes still bear witness to the hardships of the revolution, today, Santa Clara is a youthful and ferociously creative city, whose large student population contributes to the vibrant nightlife and artistic scenes, and a forward-thinking mentality, making it a unique place in Cuba.

Charismatic seaside Catania is a young, dynamic soul, inhabiting a body of narrow alleys and ornate Baroque buildings set atop well-preserved remains of ancient Greek and Roman settlements. Mount Etna defines the cityscape both in terms of the striking panorama and the building material — Catania is even referred to as the "grey city" for the colour of lava rocks used to construct many of its buildings.

Bristol, the unofficial 'Capital of the South West', has an independent spirit and a great sense of fun. You’ll find lots to make you smile here, from street art tours and music festivals to night markets and boat bars. And then there are the city’s iconic attractions: engineer Isambard Kingdom Brunel’s SS Great Britain and the Clifton Suspension Bridge, plus world-famous events, such as the International Balloon Fiesta and Bristol Harbour Festival.

Aarhus lives up to its "smallest big city" motto. It’s petite enough to conquer in a weekend, yet buzzing with enough energy to rival Copenhagen. This is where Danish hygge meets youthful innovation: think Michelin-starred dining alongside quirky food markets, avant-garde architecture framing half-timbered houses, and world-class museums (don’t miss the rainbow panorama at ARoS). By night, craft cocktail bars and live music venues prove size doesn’t dictate ambition.
