Starting in Yellowstone.
There are 4 separate entrances to Yellowstone to start this tour. Our tour focuses on the Grand Loop drive and no matter which entrance you use, the first commentary begins approximately 10 minutes before reaching the the junction where you join the Grand Loop.
West Yellowstone. It takes about 25 minutes to drive from the gate that is beside the town before you reach the Grand Loop. Launch the tour once you have driven approximately 10 minutes inside the park. The small sign for Riverside Drive is a good place to launch the tour.
Gardiner. Launch the tour as you drive through town. The first commentary begins as you approach the Roosevelt Arch.
Silver Gate, North East Entrance. Its a long approach to the Grand Loop through the Lamar Valley. Watch for herds of Bison along the way. Launch the tour once you see the Lamar Ranger Station. First commentary will be about 5 minutes ahead.
Cody. This is a long approach to the Loop. Launch the tour when you see the turn off to the Lake Butte Overlook. You will be starting to get great views of Yellowstone Lake. First commentary is about 1.5 miles past the overlook.
Starting in Grand Teton
There are 3 different places where you can enter Grand Teton National Park and each of these is a good place to start the tour – but you can join anywhere along the route.
Jackson, WY Entrance. Launch the tour at the town square (where the antler arches are). You will hear commentary as you approach the Visitor Center and start driving out of the town.
Teton Village Entrance. The tour begins as you pass the entrance to the Jackson Hole Mountain Resort Village Entrance. Best to launch the tour when you start to see the runs of the ski resort. You will hear the introduction between the resort and the Park Entrance Station at Granite Canyon.
Dubois/Moran Entrance. If you are approaching Grand Teton from the east and the town of Dubois, you will enter the Park area just before the tiny town of Moran. When you start seeing views of the Tetons (you will know), launch the tour.
