Istria
Nine days in peninsula Istria (Croatia)
At the crossroads of the Balkans, Central Europe and the Mediterranean, Istria has a fascinating history, geology, flora and fauna. In a relatively small area (about 4000 km2) one passes from a rocky coastline and a strip of Mediterranean scrub and woodland through areas of low-intensity agriculture rich in wild flowers and farmland birds.
Away from the coast, the land rises to 1000m or more above sea level with broad submontane grasslands, limestone gorges and splendid beechwoods. Beyond the Limski Kanal, a fjord-like inlet that separates northern and southern Istria, climatic conditions are similar to those found farther south in Greece and Southern Italy.
The limestone mountains of the interior are still wild and sparsely populated by Albanian and Romanian communities brought in as colonists by the Austrians and Venetians during the Middle Ages, following depopulation caused by outbreaks of the plague. As elsewhere in the flower-rich Karst, limestone areas are peppered with remarkable dolinas (swallow-holes) where the roofs of caves have collapsed, leaving hollows with their own micro-climate with a curious mixture of alpine, western European, Balkan and Mediterranean flowers.
