Heading to Agia Anna you will pass from Kireas River, located in northern Evia. This river offers the most beautiful trekking route of the island. Uncountable plane trees, flowing waters from the river and various kinds of amphibians will make you stop your car for a while and have a look at the beautiful river and landscape. River Kireas joins river Nileas and they both end up in the waters of the Aegean Sea, and more specifically on Krya Vrysi beach. Kireas River may be small, but it’s the most beautiful river of the island. Clean, frozen waters, hanging wooden bridges and stairs are everywhere in the plane trees forest and above the rivers’ waters. You should also try finding the famous Geroplatanos, which is said to be the oldest and largest tree of the whole Balkan Peninsula, located on the shores of the river. It’s a trip you shouldn’t miss!
