The Jeglinner Canal, named after the place Jeglin, is a 5 km long canal from the first half of the 19th century that connects the Spirdingsee (specifically his book Sexter See) with the Roschsee in the north-east Poland in the voivodeship Warmia-Masuria connects. It is very popular with canoeists, sailors and other water sports enthusiasts. The waterway network can be navigated with a houseboat. There are locks to be passed.
