Rocky Mountain National Park (RMNP) in Colorado is one of the most famous and highest national parks in the USA. Longs Peak is the highest point at 4,345 meters. The landscape is characterized by mountain forests with aspens, pines, and expansive meadows, where elk are common. Dense coniferous forests and mountain lakes, as well as rugged, treeless plateaus with only low-growing plants, bighorn sheep, and marmots can also be found. A highlight is the Trail Ridge Road, the highest continuously paved mountain pass in North America, leading through the alpine tundra. The most popular hiking area, with its numerous lakes, is the Bear Lake Corridor. The park is open year-round, although many roads and trails are closed during the winter months due to snow or are only accessible with appropriate equipment. Due to its immense popularity, time-slot reservations are often required for access during peak season.
