What it's actually like
Kastoria is a lake town first and a snow base a fairly distant second — and, to its credit, it knows it. The old town curls around a peninsula in Lake Orestiada, dense with Byzantine churches — dozens of them, frescoed and often locked outside services — and the mansions of the fur merchants who once made this one of the Balkans' wealthier addresses. Winter suits the place: mist lifts off the water, the lakeside cafés steam up, and everything moves at the speed of a slow rowing boat. Vitsi, 22 km out, supplies the snow — a local hill with a snowpark, lessons and sledging, pitched at families and snowboarders rather than mileage-hungry skiers.
Book the weekend for Kastoria and let Vitsi be the optional excursion rather than the anchor — the centre is modest and its programme follows conditions, so confirm it is running before driving up with ambitions. The town day writes itself: walk the lakeside loop around the peninsula, the resident pelicans and swans supervising, pick 2 or 3 Byzantine churches to actually find open, then cross to Dispilio, where a reconstructed prehistoric lake settlement stands on stilts over the shallows. Nymfaio, one of the region's showpiece stone villages, is a worthwhile hour away. Warnings, plural but gentle: lake fog can flatten the light for days, and January cold here is serious. Both, arguably, are part of the point.
