The lake was created by a landslide that occurred over the course of three days in February 1950, blocking the natural flow of the Derecik stream.
The geological event that formed the lake destroyed 16 homes and several agricultural lands in the valley.
The water level is highly dynamic and significantly influenced by the high rainfall characteristic of the Eastern Black Sea region.
The basin serves as a natural catchment area for sediment, which continuously alters the lake's bottom topography.
The surrounding forest area is a protected habitat for various bird species and small mammals common to the Pontic Mountains.
Sera Lake is a landslide-dammed lake located within the Söğütlü Valley in the Akçaabat district of Trabzon. The lake was formed in 1950 following a massive landslide on the Derecik stream. It occupies a basin spanning approximately 17 hectares and reaches a maximum depth of around 55 meters. The surrounding landscape consists of dense broad-leaved forests, primarily beech, hornbeam, and spruce. In 2010, the area was officially designated a nature park to preserve its unique ecological status. The lake's surface area fluctuates seasonally due to the influence of the Derecik stream's water intake. Visitors can access a perimeter walking path that circles the lake to observe local flora and fauna. Facilities including wooden piers and seating areas have been constructed to facilitate recreation around the waterfront.
The wooden jetty near the main entrance offers a clear, unobstructed panoramic view of the lake against the forested valley walls.
Bring waterproof footwear as the perimeter path can become muddy after rainfall.
Visit during the shoulder seasons to avoid high-density tourist crowds during mid-summer weekends.
Carry a windbreaker or light jacket even in summer due to the rapid temperature drops common in deep valleys.
Avoid relying on swimming, as the water can be cold and contain underwater debris from the original landslide.
Maintain silence near the water's edge to avoid disturbing wildlife and respect local signage regarding waste disposal.
