The water is warm even in the early morning, when the surface of the lake is still and the reeds cast long shadows on the shore. There are no signs, there is no bathing facility, there is nothing to indicate the presence of these hot springs except for the thin steam rising from the water in the colder months and the trace of a path worn by the feet of those who have frequented them for generations. We are in Kavros, in the Rethymno prefecture, in the northwest of Crete, and Lake Kournas — the only freshwater lake on the island — hides along its eastern shores something that tourist guides rarely mention.
The geothermal springs seep into the sandy and clayey bottom of the shore, mixing the freshwater of the lake with heated mineral inputs from deep below. The result is a series of shallow pools, accessible on foot, where the water temperature exceeds that of the surrounding lake in a way that is perceptible to the touch. These are not equipped tubs nor wellness centers: it is a natural phenomenon that the local residents have always known and used, passing down the way to reach them from generation to generation through oral directions.
The geography of a unique place
Lago Kournas is located about 4 kilometers south of the coast, in the hilly inland between Georgioupoli and Rethymno. It stretches for about 600 meters in length and reaches depths of up to 30 meters at the central point, but along the eastern shores, the bottom gently slopes and the water remains shallow for several meters inland. It is precisely in this area that the hot springs emerge from the underground, creating zones where the heat is clearly felt compared to the average temperature of the lake, which in summer hovers around 22-24 degrees.
The landscape surrounding the lake is dominated by the hills of the Lefka Ori mountain range, the White Mountains, visible to the southwest. The reeds form a natural barrier along part of the shore, and the Mediterranean vegetation — wild olives, mastic trees, tamarisks — descends to the water in some stretches. The freshwater turtles of the species Mauremys rivulata, present in the lake, are easily spotted on the rocks during the central hours of the day.
The therapeutic experience of the springs
Diving into the thermal pools of Kournas is a sensorially layered experience. The heat rises from below, from the bottom, in a diffuse and uneven manner: there are points where the temperature is more intense, others where the water is just slightly warmer than the lake. This natural gradient allows for a slow movement between areas of different temperatures, getting closer to or further away from the points of emergence of the springs. The water does not have a strong sulfurous smell like in many classic spas, but leaves a feeling of softness on the skin that local habitués attribute to the mineral content.
The tradition of the therapeutic use of these waters is rooted among the inhabitants of the nearby villages, particularly those of Kournas and Kavros. Locals report that their parents and grandparents frequented the springs to relieve joint and muscle pain, especially during the autumn months when the lake is less frequented by tourists. There are no formal historical documents of this use, but the continuity of the practice is evidenced by the presence of the access path, clearly maintained by regular use.
How to reach the springs
The path starts from the main parking area of the lake, where there are some local taverns that also rent pedal boats. Following the shore eastward for about 400-500 meters, passing the taverns and venturing into the less frequented area, you will encounter the stretch of shore where the springs are active. There are no signs: the route requires following the trail in the vegetation and paying attention to the consistency of the bottom, which in some places is softer and muddy.
The best time to visit is early in the morning, before 9:00 AM, when daily tourists have not yet arrived and the slanting light on the mountains makes the landscape particularly clear. In summer, the lake is very crowded during the central hours of the day, and the crowding reduces the quality of the experience. The months of September and October offer ideal conditions: the lake is still warm, tourists thin out, and the springs are easier to perceive because the outside temperature drops. It is advisable to wear water shoes to walk on the bottom and bring water, as the path has no services.
Practical tips for the visit
Kavros is easily reachable by car from the provincial road that connects Georgioupoli to Rethymno. The parking near the lake is free and spacious. There is no entrance fee to access the lakeshore or the springs. The taverns by the lake serve traditional Cretan cuisine and are a good reference point to ask for directions from the local managers, who generally know the way to the springs and are willing to point it out.
Those who visit the lake only for the conventional tourist part — pedal boats, swimming in the lake, lunch by the shore — are unlikely to learn about the springs. This keeps them in a state of relative tranquility and authenticity that is worth preserving: no litter, no equipment brought on site, no excessive noise. The Kournas springs work because no one has turned them into an attraction.
