Denali Tri-Valley Cabins does not offer any shuttle service. To get to and from the Train Depot or bus/shuttle stops we suggest you use Keys to Denali Car Rental. http://denalidomehome.com/Denali-Park/car-rental-denali/ They will pick-up and drop off at any Denali area location. This affords you the optimum flexibility in getting around the Denali area.
There is also a local taxi service and a shuttle that runs from Healy to Denali business district.
Most years there are some UBER drivers as well.
