Vanajõe valley is a place that confirms that Hiiu County has it all: rivers, lakes, hills, and valleys. The valleys in particular seem quite unusual in this environment, because it seems impossible to go below sea level on such a flat landscape. Nevertheless, the valley with its high sandy banks and mysterious brownish water is a true treasure. The running water has shaped a deeper and more natural base for itself in the soft sandy soil.
February daphne grows profusely here, the sea trout comes to spawn here, and the European weasel tries to regain foothold. Coloured earth has also been found in the Vanajõe valley, which was dissolved in water and used for painting houses.
