Because of its proximity to Zagreb and bridge access, Krk Island has become one of the Adriatic’s most popular tourist destinations. All the action takes place in Krk Town, especially in the walled Old Town which houses the remains of the ancient Roman walls and city gates.
Apart from the gates and walls, there’s the Cathedral of the Assumption dating back to the 12th century with its Baroque domed bell tower and wooden angel perched on top. There’s a treasury in the adjoining Church of St Quirinus, Krk’s patron saint, which offers a wonderful example of Romanesque architecture from the 12th century.
The Kastel, a Frankopan seafront castle-fortress built between the 12th and 14th centuries can be wandered for free, but if you want to climb the 12th century tower, it will set you back about 10KN.
The Kastel lies next door to Kamplin Square where you can find remnants of the Roman temple columns. On Mahnica there are remains of the Temple of Venus dating back to the first century and the only temple dedicated to the goddess Venus in Croatia. On Ribarska lie the remnants of Roman thermal spas on the ground floor of the Vasilic House. These are from the 1st century and depict the mythological scene of Triton with dolphins and sea creatures dancing.
At Kosljun a tiny island only six kilometres from Krk Town there’s a must-see 16th-century Franciscan Monastery. Give yourself atleast half a day to visit the monastery, that was built on the site of a 12th-century Benedictine monastery with it’s Ethnographic and Sacral Museum and to wander around the forested oasis of this islet. You can get a taxi-boat shuttle at Punat.
Bike rentals are available to see the rest of Krk island which must include the medieval hamlets of Vrbnik and Baska, both are surrounded by some good swimming beaches. There are diving schools in town offering dives and courses to get the beginner started.
