Best season is during the warmer summer months. There is not much wildlife in the winter due to hibernation. Denali also has a rich and amazing flora. Wildflowers begin to bloom in early June till late July.There is only one road in Denali. Private vehicles can drive a small part of it, but most of the road is open only to bus traffic. Bus trips are available only in summer (roughly mid-May through mid-September). All bus trips are operated by a private company with a contract to do so - not by the National Park Service.Denali is definately worth it. Spend some time and get off the bus and do some hiking in Denali. Also, if you can afford it - try to go on a Mt. McKinley flight tour with a company like Talkeetna Air Taxi, or someone else.Three days will get you deep into the heart of Denali National Park in a way that is much more enriching than a quick day visit. You'll have time and space to soak in the grandeur and the vastness of Alaska's most iconic national park. Three days in Denali is just good for the soul!
