The Göta Canal is the most famous canal in Sweden. It and the Trollhätte canal together canal enable boats to transit from Göteborg to Stockholm, crossing the country.
The canal was built in the early 1800’s for military reasons. Total length of the canal (not including Trollhätte canal) is about 120 miles. It has 58 locks which can handle boats up to 98’ long, 23’ wide and 9’ deep. Overhead limit is 72’, which means this route is a favorite for sailboats. The locks, for the most part, are manually operated -- typically by students on summer holiday.
Today, it serves 99% pleasure boats, along with a few historic passenger ships. For a 33’ boat, a pass costs about $900 US, which includes all marinas, electric, water, toilets, showers, etc. for the entire summer. Boats are available to rent on a weekly basis for locals and visitors flying in from abroad. Typically 30-40’.
