Good option for West Yellowstone
Be aware there are two KOA’s just a few miles apart. The mountainside one snuck up on me and I missed the turn, had to turn around at the other KOA.
Short drive to Yellowstone west gate. Friendly staff, good location. Good sites. More tent campers than your average KOA.
Lots of campfires here every night, so if you are sensitive to smoke be aware of that.
We had a good stay here, would return.
