Sevan

The pearl of Armenia - Lake Sevan! Coming to Armenia and not visiting Sevan, not admiring its enchanting beauty, not visiting the churches on the top of the Sevan peninsula, not swimming (or, if it's not the season, at least washing with lake water), not tasting Sevan fish cooked over coals and crayfish kebab made from crayfish necks is at least criminal. It is worth noting that this is the largest lake in the Caucasus, as well as one of the largest high-altitude fresh lakes on Earth, second only to Lake Titicaca in terms of freshwater resources.
