Forellenvisserij De Slegge is a recreational trout-fishing venue situated in the rustic surroundings of Ter Apelkanaal in the Westerwolde region of Groningen.

The site features several purpose-built fishing ponds stocked with trout, salmon trout, catfish, and sturgeon, making it suitable for both beginners and experienced anglers.

Visitors can fish by the half-day or full day, and there are no fixed start times, so anglers can begin at any point during opening hours. Rods and bait are available to hire on site for those without their own gear.
