Hello there,
I just got this info from world wide web.
Denali Bus service departs Anchorage at 7:00 a.m. and arrives in Denali around 12:30 Bus Anchorage to Denali Parkp.m, in time to catch connecting buses into the park or buses heading to lodges in Kantishna. Retuning to Anchorage depart Denali at 1:45 p.m. picking up guest at local hotels and arrives back in Anchorage around 8:00 p.m.
Another option is the Alaska Railroads Denali Star Train, departs Anchorage at 8:15 a.m. and arrives in Denali at 3:45 p.m. If you're not on a tight budget the GoldStar first-class dome car upgrade is well worth the money. Returning from Denali the train departs at 12:15 p.m. and arrives in Anchorage at 8:00 p.m. Backcountry Safaris would be please to make reservation for you at no additional cost to you and answer all your Alaska travel questions.
Cheers...
