The Mulbjerge are said to be a remnant of the Ice Age. The majority is overgrown with forest. The ones marked here are grassy round hills. Like the Highlands in miniature. They appear much larger than one would expect with their height of up to 48 m and provide a magnificent all-round view.

Ravnkilde is located in the eastern part of Gravlevdalen, north-northwest of the Rebild Bakker. The source is easily accessible. It can be reached from the parking lot at Lars Kjærs Hus. Ravnkilde is exceptionally beautiful and is surrounded by forest on three sides. Due to nature conservation, it is forbidden to step into the spring. However, the forest district has placed stones in the spring so that it is possible to cross the spring without your shoes getting wet and without coming into contact with the water. Ravnkilde is a swamp spring with small brooks that collect from the swampy spring field into the finished spring brook. The water flow is quite large. Every second 85 liters of water flows past the centuries-old ford on the way to Lindenborg Å. The spring water is warm between 7 and 8 degrees all year round. On clear, frosty days, the spring steams and there are green plants in the middle of the snow. Ravnkilde is rich in small animals (over 200 different species) and the constant water temperature all year round provides living conditions for animals that are more likely to be found in colder or warmer areas in Europe. These immigrated to Denmark in the cold and warm periods that emerged after the Ice Age, and survive here today due to the low summer or higher winter temperatures of the spring in relation to the surroundings. https://www.rebildporten.de/tourist/planlaeg-din-tur/ravnkilden-quelle-gdk679414
