The Snitser Aldfeart is an old river ("aldfeart" meaning "old river" in Frisian) that winds through the lowlands surrounding Sneek in the province of Friesland, Netherlands. It connects the town of Sneek with the hamlet of Easterwierrum, offering paddlers a route through open, flat agricultural landscape with broad views characteristic of this part of Friesland.

The waterway is classified as category E, meaning boats with a draft of up to 1.0 meters can navigate it. The route is suitable for SUP boards, canoes, and electric sloops. Paddlers should be aware that the route passes through two small locks, so some basic lock-handling experience is useful.

A well-documented paddling route uses the Snitser Aldfeart as its first leg, starting at Pasfeardyk 6 in Sneek (postal code 8631 SK). From there, paddlers head out over the Aldfeart toward Easterwierrum, where the route connects with the Zwette canal — a waterway in category DM, navigable by boats with a draft of 1.3 meters and a height of 2.3 meters. The Zwette is part of the historic Elfstedentocht route, famous for both ice skating and boating. Paddlers can return to Sneek along the Zwette, completing a loop of approximately 19 kilometers in total. At a beginner's pace of around 3 kilometers per hour, this constitutes a full-day outing of more than six hours.

Along the way, the Loënga Bell Tower is noted as a landmark on the route. The route passes through open lowland terrain, offering unobstructed views across the Frisian countryside.

Paddlers are encouraged to practice leave-no-trace principles on the water, including removing any litter encountered along the route. Boat rental is available at various locations in Friesland for those without their own equipment.
