Fishing Bridge RV Park is Yellowstone’s 310-site campground for hard-sided RVs, near where the Yellowstone River leaves Yellowstone Lake at about 7,800 feet. It’s a practical base around the lake and East Entrance road, more useful for its location and hookups than as a scenic stop in its own right. It is the park’s only campground with full water, sewer and electrical hookups. Tents and tent camping are prohibited because this is grizzly bear country. Reservations are required, and the campground operates seasonally, so check current dates before planning a night here.
