I haven't made the dogsledding yet, canceled upon twice, It is the inside passage most canceled excursion. It is not only dependent on the snow conditions but weather as well, on a glacier landing helicopeter tour, there are many landing sites, but only one dog sledding area. Consider going out of Skagway booked direct via TEMSCO. I wouldn't double book unless you are prepared to go twice. Only option for a Juneau booking will be through the ship excursion via ERA.
