Crete’s only freshwater lake is a beautiful change of pace from the salty coast. Ringed by the White Mountains, Kournas changes color from a vibrant turquoise at the shallow edges to a deep navy blue in the center. Rent a pedal boat to slowly explore the water, and keep an eye out for the tiny terrapin turtles and eels that live here. It is a peaceful, refreshing spot to connect with the island's inland beauty.
