West Yellowstone Rest Area Northbound

This is a large pullout on Highway 191 just a mile or so outside of West Yellowstone. It has 6 or so marked lanes for 18-wheelers as well as RVs. There’s also plenty of space for small rigs and vans to park along the edge, leaving the lanes for the bigger guys. We parked in the far left lane and had room to put our slide out. There are no restrooms or trash disposal bins. It is bordered by the forest, so has a nice place to walk the dog (remembering that bears share that forest).
We arrived about 5, and were the first ones there. It got about half full overnight, including some 18-wheelers, but no one idled for any length of time. The road noise was not noticeable after 10pm (and I am sensitive to noise).
There is an identical lot on each side of the road. Highway 191 is a small road, and it is easy to pull into whichever lot is best for you.
We found this spot very convenient on the day we left Mammoth Campground in YNP to head south to Idaho. We were able to grocery shop, buy propane, and do laundry in West Yellowstone before coming to stay overnight here.

Both the north bound and south bound sides of this tiny pull-off/rest area have multiple “No Camping” and “Day Use Only” signs. We took that to mean no overnights, as multiple other pull offs in the West Yellowstone area also having “No Camping” signs and don’t allow even single overnights. Personally, we didn’t try sleeping here because we try to avoid knocks on the door telling us to move.
