Can anyone give me any input on the Glacier Lake Kayak & Scenic Railway excursion? I know I want to take the White Pass Scenic Railway but am unsure about the kayaking part of the excursion. I'm also considering the Klondike Bicycle Tour, but I understand that you can rent a bicycle in town, take the railway up to Frazier and then ride down on your own. The only downside to the latter, according to the person I talked to, is that you have to go slightly uphill for approximately 4 to 5 miles before you go downhill. Has anyone tried either one of these, and do you know how much of an uphill climb you would experience if you rented the bicycles on your own?
