West Yellowstone - Old Mill Trail

Located 5 minutes from West Yellowstone, there are plenty of open spaces in this forest, but it fills up quickly. It's only accessible in the summer, not in the winter, as there are snowmobile trails. If you can't find a space on Radio Rd, continue straight ahead on FS1700 Plateau Rd. There's more room for RVs and larger cars, but it's not very flat. The spot we stayed at was the flattest we could find for our 24-foot RV. You can also walk from here to town—it's a 15-20 minute hike.
