I am planning a trip to Banff National Park and I am wondering when is the best time to visit? I am looking for a time when I can enjoy the natural beauty of the park, as well as experience some of the activities that the park has to offer. I am hoping to find a time when the weather is mild, the crowds are not too large, and the prices are reasonable. I am also hoping to experience the wildlife and the unique landscapes that the park has to offer. Any advice or suggestions would be greatly appreciated.
