The Drentsche Aa is a river system flowing through the provinces of Drenthe and Groningen in the Netherlands. Its final stretch, specifically called the Drentsche Aa, is located in the province of Groningen as it flows towards the city of Groningen, ending in the Schipsloot near Haren. This water body is central to the Nationaal Park Drentsche Aa, a national park and national landscape. The river system is noted for being one of the last unregulated and well-preserved river systems in the country, characterized by a meandering course through a varied landscape. The terrain surrounding the river in this area features traditional hay meadows, heathlands like the Gasterse Duinen, ancient woodlands, and gentle slopes. The overall character of the paddling experience is defined by this unspoiled, natural setting with significant historical and cultural elements, including ancient monuments and a landscape shaped by centuries of traditional land use. The path along the river connects the city of Groningen with Zuidlaren via natural landscapes. The Paddleways website is a resource for uncovering paddling access points, boat ramps, and facilities. The river's water ultimately flows into the Lauwersmeer and the Waddenzee.
