1 DUBROVNIK'S CITY WALLS
The unyielding stone walls rise straight up from the sea and rock, almost daring their attackers to try to scale them. And as impressive as it is to walk the 2km walls and look out to the horizon, squinting to try to imagine what it might have been like spotting enemies approaching, it's impossible to truly appreciate their scale until you're in the position of someone sailing across an ocean to invade.
Bobbing up to the walls in a comparatively tiny yacht really gives you a sense of scale and an appreciation for how on earth they were built.
2 THE ISLANDS
With its clear, azure waters, Croatia is all about what lies off the mainland. The Dalmatian Coast is scattered with islands that easily rival their more commercial neighbours off nearby Greece.
From the walled Korcula — which prides itself on being the rumoured birthplace of Marco Polo and offers a less crowded walled-city experience than Dubrovnik — to the superyacht and socialite laden Hvar, all can be hopped within a few hours. But why not head further afield and take in the stunning national park on Mljet? With a tiny island, in a lake on an island, it's just begging to be explored — preferably by bike.
3 IT'S HOT
During peak season, Croatia gets hot — really hot. In August, Split and Dubrovnik will often get hotter than 30C, which feels even hotter as the historic stone buildings trap the heat. The only cure is a light sea breeze or a dive straight into the cool sea.
