Hi everyone. I worked for Princess as a seasonal employee as a tour bus driver in 1990 and 1991. I enjoyed my time there greatly and would love to go back again!
There is not a bad time to visit Alaska, in my opinion. Early in the season there may still be some snow on Mt. Healy and you may see some ice on some roads, but you have the beauty of the newborn moose, the rapid rise of greenery and wildflowers up the sides of the mountains. My first year at Princess we took a helicopter tour and saw a grizzly and her two cubs with a fresh kill. What an amazing experience. A "traffic jam" between the lodge and the train station is not uncommon due to busses stopping for photo opportunities....those being mother moose and her babies. We even saw a moose give birth on the roadside one year. If I remember correctly the birthing season only lasts 2 weeks.
Another thing that I wouldn't miss is the airboat tour back to the trappers tents. I don't remember exactly what the tour was called. But you boarded a Princess bus and took a 20 minute drive ( we never failed to see wildlife on this trip) to an airboat. That boat took you up the Nenana River to a trappers camp. You drink camp coffee, pan for gold, learn about trapping etc. Very informative and fun. A great way to experience the real Alaska.
The further into the summer you go, the less likely you are to see "the mountain". That of course being Denali, or Mt McKinley. She is a beautiful sight. Unfortunately summer months leave her mostly enshrouded in clouds. The closer to winter you are, the better your chances of seeing her.
Late summer season is a time of quick change. When we drove the busses to Anchorage at the end of the season the last year I was there, it was about 20 degrees and there was several inches of snow on the road in places! Talk about a ride! And that was in September.
Don't miss the mushing exhibition put on by the park service in Denali. It's great fun to see the dogs do there stuff! Assuming you take the train and visit the park.
All in all, Alaska is a great experience. The land tour is definately worth taking. We rode the train a few times on our off days and it was always enjoyable.
Enjoy whenever you go and watch out for the moose and the grizzlies!
