Tourism is a major industry in Croatia. In 2012, Croatia had 11.8 million tourist visitors, and in 2015 it had over 12 million tourists and 90 million nights. Croatia aims to double these numbers by 2020 with national strategy to bring in 17.5 million foreign tourist and revenue from tourism exceeding $17 billion.
Tourism in Croatia is concentrated in the areas along the Adriatic coast and is strongly seasonal, peaking in July and August.
Eight areas in the country have been designated national parks, and the landscape in these areas is afforded extra protection from development. Several companies run flotillas of yachts along different stretches of the coastline, which is also popular with divers.
Lonely Planet named Croatia as the top pick destination for 2005, while National Geographic Adventure Magazine named Croatia as Destination of the Year in 2006.
The Croatian National Tourist Board has divided Croatia into six distinct tourist regions.
The west coast of the peninsula of Istria has several historical towns dating from Roman times, such as the city of Umag, which hosts the yearly Croatia Open ATP tennis tournament on clay courts.
The city of Poreč is known for the UNESCO-protected Euphrasian Basilica, which includes 6th century mosaics depicting Byzantine art. The city plan still shows the ancient Roman Castrum structure with main streets Decumanus and Cardo Maximus still preserved in their original forms. Marafor is a Roman square with two temples attached. One of them, erected in the 1st century, is dedicated to the Roman god Neptune. Originally a Gothic Franciscan church built in the 13th century, the 'Dieta Istriana' hall was remodeled in the Baroque style in the 18th century.
