West Thumb to Old Faithful Section of Grand Loop Road

The Grand Loop Road in Yellowstone is the main method of travel through the park. It is shaped like a giant figure eight. Sections of this road are usually referred to by the two “junctions” that the section runs between. Below is the description of the road between West Thumb Junction and Old Faithful. For an index of all road sections in the park, see the Yellowstone Roads index.

Mile 0 – West Thumb Junction

The Grand Loop Road and the South Entrance Road intersect at West Thumb Junction. The South Entrance Road heads south, eventually leading to the John Rockefeller Memorial Parkway and Grand Teton National Park. The Grand Loop Road heads to the northeast on the Fishing Bridge to West Thumb section and west to the Old Faithful Interchange, as described below.

Mile 15.2 – Lone Star Trailhead

Mile 15.4 – Kepler Cascades

The parking area for the Kepler Cascades is on the left. A platform provides a good view of this large, multi-level cascade of over 100 feet.

Mile 17.9 – Old Faithful Interchange

The road arrives at the Old Faithful Interchange. This is an interchange in the true sense of the word, complete with ramps that look like they belong on an interstate freeway. Yes, this area of the park is that crowded, but for very good reason. A right turn onto the ramp leads to the Old Faithful complex. Straight ahead is the Old Faithful to Madison section.
