Sió

The Sió is a regulated waterway that connects Lake Balaton to the Danube River over 124 kilometers, flowing through Somogy, Fejér, and Tolna counties. The system comprises locks, dams, and control structures that manage water flow throughout the route.

Engineers built this canal in the late 19th century as part of extensive hydrological controls to manage Lake Balaton water levels. The construction established a new connection between the lake and the Danube River.

The canal is part of regional water tourism networks and connects multiple Hungarian waterways. Visitors use it for paddling sports and experience the rural landscapes along its route.

The canal has multiple access points along its length, though not all sections are equally accessible. Visitors should prepare for changing water conditions and local weather patterns.

The system regulates outflow from the lake during wet periods but also allows water to return during dry seasons. This dual function makes it an essential part of regional water management strategies.
