Boundary Road serves as the border between Grand Teton National Park and Bridger-Teton National Forest and offers spectacular views of the Teton Range as you pedal this forest service road. A hybrid or mountain bike is required since the gravel road is a bit rough, but that also means it is rarely traveled by motor vehicles...
You admire unending sagebrush flats on the eastern slopes of the mountain range as you look for antelope and buffalo, all with the towering Teton Mountains to your west while you pedal at 8000 feet altitude looking down at the Jackson Hole Valley below.
After passing the obvious at-large camping area on the left in the national forest, you'll hit the paved Antelope Flats Road where you turn right (downhill) towards Highway 191, but when you see the structures, turn left onto Mormon Row and check out this historic location settled by 11 Mormon families a century ago.
The buildings had fallen into disrepair for years after the National Park Service took over the properties, but in the 1990s many of them were rehabilitated. The famous Moulton barn and homestead below is reputed to be the most often photographed barn in the country, as it has been featured on many calendars over the years.
We then biked Mormon Row Road, turned left onto a gravel double-track, left again onto Gros Ventre Road for lunch at a nice pond after our 20+ mile ride.
