Glacier dogsled tours stop operating for the season at the end of August. By that time, the snowmelt poses unsafe conditions for the dogs so they are taken off the glacier. We do, however, still offer many glacier helicopter tours as well as dogsled tours at the musher camps in town.As far as the best time of day for helicopter tours, there really isn't a best departure time. Predicting the weather in Alaska, especially Southeast, is nearly impossible. The morning and the afternoon are just as likely to be nice or rainy, so our recommendation is to choose your preferred departure time and hope for sunshine! Of course, if your tour is weather canceled, we provide a refund.
