Rocky Mountain National Park is beautiful, no matter the season. But come September, the park lights up with pockets of gold from the yellowing aspens and becomes a haven for wildlife viewing with the elk rut in full swing during the fall season.
Visitors to the park can enjoy bugling elk, the changing of the leaves, fewer crowds, and moderate temperatures, making autumn one of the best times to visit the park. One of the best ways to experience Rocky Mountain National Park (RMNP) in autumn is with its many hiking trails and scenic drives.
