America’s national parks are becoming more and more crowded. Some parks are extremely busy during the summer.

Out of necessity to preserve fragile ecosystems, some of the more popular are choosing to restrict visitor traffic with a reservation system.

Acadia National Park, located near Bar Harbor, Maine, is among the smallest and most popular national parks in the United States with more than 3.5 million visits a year. Growing visitation has caused severe traffic and parking congestion at the park’s most popular destinations. Recreation.gov has info on gaining access to the Cadillac Summit Road.
