Ranger Program Schedules. Getting to the kennels for a summer sled dog program involves arriving at the Denali Visitor Center 45 minutes before a sled dog demo begins. There is no parking available at the kennels, so park at the visitor center (if you have a car) and ride a free bus to the demonstration. Alternatively, you can walk the Rock Creek (~2 miles, 90 minutes) or Roadside Trail (~1.5 miles, 60 minutes) from the visitor center to the kennels.
