The Croatian peninsula of Istria is particularly popular for a graduation trip to the glittering turquoise-blue Adriatic Sea. Fantastic sunny beaches and natural paradises offer great activities and picturesque coastal towns fascinate with romantic alleys, harbour promenades and breathtaking sunsets. In Pula, the Roman amphitheatre is impressive. From Rovinj, a boat tour takes you along the karstic Limski Fjord. Rocky bays reach inland, where olive groves surround enchanting mountain villages and avenues of cypresses line the vineyards.
Venice or Slovenia - and also enchanting national park islands with rushing waterfalls - are within easy reach in this corner of the Adriatic coast.
