About 150 km (93 miles) to the north of Berlin, Müritz National Park is a glacially created reserve where a number of rare and endangered birds make their homes. Müritz is a large conservation that has many tiny lakes and a plentiful variety of landscapes (grassland, marsh, wetlands, beech forest, inland sand dunes, etc.) for travelers to venture through. Although you'll not get the big mountains of southern Germany or unique rock formations of the east, this is a great place to enjoy a unique variety of biomes and view unique creatures in one space.
GPS guides can be borrowed from the park tourist office to provide access to a number of coordinated hikes. There are also cycling routes and canoeing activities available on many of the lakes, with the appropriate equipment available at the park office. Check the park website for further information.
