In looking at a book I received “The 2022 official Vistors Guide” Juneau Alaska, show only two companies do helicopters dogsled tours; Temsco and Costal. I believe the Cruise Lines use both. If the two companies have cancelled, I would almost be assured that the cruise line will cancel. I was told months ago by both companies basically, if the snow disappears the sled tours no longer run. I had originally book our cruise in late September for my husband’s birthday 2023, and noticed there were no sled tours. This was because no snow confirmed both companies I changed our sailing to May. I am hopeful that we will get to go as this was my husbands favorite excursion. The latest they generally schedule is the first week in September .
