The freshwater from the Almyros River lowers the salinity of the water at the shore, altering the density and swimming experience.
The temperature difference between the river water and the sea can reach several degrees, providing a cooling effect during heatwaves.
The site is located at the estuary of the Almyros River, one of the primary sources of fresh water in the Apokoronas region.
The distinct mixing of cold freshwater and warmer seawater creates visible optical distortions known as thermoclines.
The surrounding lagoon is a critical wetland habitat for local waterfowl in the Georgioupoli area.
Kalyvaki beach is a unique coastal location in Georgioupoli where a freshwater spring flows directly into the sea, creating a distinct temperature gradient. The water remains significantly colder than the surrounding Mediterranean due to the inflow from the Almyros River. The beach surface is composed of fine, golden sand, transitioning into pebbles near the water's edge. Because of the freshwater influence, the water clarity is exceptionally high and often creates a shimmering visual effect. The beach is sheltered from strong winds, making the water surface generally calm. It is situated adjacent to the mouth of the Almyros River, which creates a small lagoon environment that attracts various bird species. The area is publicly accessible and features a mix of serviced sections and natural shoreline. The sea floor shelves gently, making it suitable for swimmers of various ability levels.

Bring water shoes to navigate the transition zones where the riverbed meets the sandy beach.
Check the water temperature before swimming, as the river inflow makes it noticeably colder than typical Cretan beaches.
Stay on the left side of the beach for a quieter experience closer to the river vegetation.
Do not swim directly in the narrowest part of the river mouth where current speed can be deceptive.
Respect the fragile wetland ecosystem of the riverbank; do not disturb nesting birds or plant life.
