Opatija - 170 years of tourism:

Opatija – the cradle of European and Croatian tourism, a favourite destination of the aristocracy, film and music stars, artists, writers and visitors from all over the world, who come here every year to enjoy the charm of this Adriatic town – this year celebrates its 170th anniversary as a tourist resort.

This is a tradition that provides certain obligations, but is also a guarantee of quality. The reputation of a top destination that stretches back seventeen decades is today reflected in the wide range of facilities and services on offer that all together make Opatija an attractive destination for all seasons.

Opatija owes its unique image to its ideal location on the spot where the wooded slopes of Mount Učka descend all the way down to the coast, providing perfect shade along the thirteen-kilometre-long Lungomare seafront promenade. Just as the Opatija area is a meeting point of the sea and the mountain, its visual impression is a blend of different styles, as this is a melting pot where magnificent Central European elegance, playful Mediterranean charm and the historically-rich medieval architecture of the small towns in the hinterland come together. 

In addition to the architecture that leaves a strong impression on every visitor, especially when the town is viewed from the sea, and its lush parks and gardens that have been Opatija's trademarks since its beginnings as a tourist resort, Opatija also has hotels and restaurants whose quality ranks alongside that of any other European destination. Opatija's gastronomic offer is based on a Mediterranean cuisine rich in fresh fish and seafood and locally grown seasonal ingredients, while the traditional recipes of this region reveal a wealth of flavours and can be sampled in the area's numerous taverns. 

Opatija entered the European stage in the mid-19th century as a health resort for the European nobility, and health tourism has remained one of the main segments of the town's tourism offer right up to the present day. However, top medical experts and a wide range of spa & wellness services are just one of the reasons for visiting this town located at the top of Kvarner Bay. Also known as "the town of festivals", Opatija boasts a number of events throughout the year. The theatrical performances and concerts that take place at the magnificent Open Air Theatre are particularly impressive.
