There is a road that leads to an oft-ignored corner of Yellowstone National Park.
At the park boundary is a gate and a little ranger outpost mostly built by soldiers in 1911.
The road dead ends here and no cars may pass beyond this gate. If you want to continue, you must do so on foot or on horseback.
There is no gift shop, no place to buy a sandwich and a smoothie. No lodging except for a smattering of designated campsites you can hike or ride to, miles from where you leave your safe, air-conditioned steel capsule.
For all of the above reasons, few visitors to YNP ever go here. Most don't even know it exists as an alternate entrance. You could walk from this place all the way to the more popular, inundated parts of the park if you had a mind to. Or, on one of the busiest long weekends of the season, you could relish that there are still places in the park where you can stay well clear of all that...
