Jachthaven Cnossen Leekstermeer is a marina and watersport centre situated directly on the Leekstermeer, less than twenty minutes by car from Groningen.

Its position on through waterways makes it a convenient departure point for boaters heading toward the Frisian lakes, the Wadden coast, or the city of Groningen. Passing boaters are welcome to stop, and mooring and storage facilities are available on site.

The facility combines several functions in one location, including a sailing school, camping, and holiday accommodation.

Kayak rentals are also offered, and the centre serves as one of the access points for paddling routes that connect the Leekstermeer with surrounding waterways such as the Lettelberterdiep and the Onlanden nature area.
