Rocky Mountain National Park
President Woodrow Wilson said yes to the Rocky Mountain National Park Act on January 26, 1915. This set the borders for the park. It also protected the area for future generations. The Civilian Conservation Corps built the park's main road, Trail Ridge Road, in the 1930s. In 1976, UNESCO made the park one of the first World Biosphere Reserves. In 2018, more than 4.5 million people visited the park. The park is one of the most visited parks in the National Park System. It was the third most visited national park in 2015. In 2019, the park had 4,678,804 visitors, which was a 44% increase from the number in 2012.
