The Onlanden is a wet nature area southwest of the city of Groningen where the water moves with the sound of a few streams (Eelderdiep and Peizerdiep) and the Leekstermeer lake. De Onlanden is een nat natuurgebied ten zuidwesten van de stad Groningen waar de grondwaterstand meebeweegt met het peil van enkele beken (Eelderdiep en Peizerdiep) en het Leekstermeer.
The water of Lake Louise has an emerald colour which comes from rock flour carried into the lake by melt-water from the glaciers that overlook the lake. The view from above can be reached by a nice, not too strenuous hike. Do mind the weather though, on the way back we really got soaked in a heavy thunderstorm.
