The landscape of Colorado's Front Range is dominated by the Rocky Mountains, allowing for a wealth of outdoor activities and year round attractions. For visitors desiring to spend some time in the outdoors, a trip Estes Park offers access to Rocky Mountain National Park, where hiking, biking and camping are popular summer excursions and opportunities for skiing, snowboarding and snowshoeing abound in the winter. Boulder is famous for its 33,000 acres (13,354 ha) of parks and trails, many of which are included in the Open Space and Mountain Parks, offering a variety of areas for all levels of biking, hiking and exploring. Several planetariums are found in the Front Range, allowing the nighttime to be examined at the Sommer Bausch Observatory and the Discovery Science Center. Higher education is well represented in the region as well, with Colorado State University in Fort Collins and the University of Northern Colorado in nearby Greeley.
