With thousands of miles of seafront and more than a thousand islands, Croatia's coastline is Central Europe's Riviera. Holiday-makers love its pebbly beaches, balmy summer weather, and dramatic mountains. But there's history here as well: from ruined Roman arenas and Byzantine mosaics to Venetian bell towers, Habsburg villas, and even communist concrete, past rulers have left their mark. Most travelers flock to the Dalmatian Coast, where dramatic cliffs rise from the deep and islands are scattered just offshore. But savvy travelers make time for more: the Venetian-flavored Kvarner Gulf and Istrian Peninsula, the stunning waterfalls of Plitvice Lakes, and Zagreb, the nation's engaging capital.
