In August I will be on a Holland America cruise/tour stopping for two nights in Dawson City with an optional side excursion to Tombstone. Any advice on specific tour areas of this park? Options include: Chapman Lake Coach Tour; Exploring Along the Dempster Highway; Grizzly Lake Hike; Hart River Road Hike; and North Klondike River Hike. I'm hoping for splendiferous scenery, wildflowers, etc. I'm hoping that someone has visited here before and can offer some words of wisdom. Thanks for your help.
