Fishing Bridge is the only hard sided RV only, full hook-up campground that can accommodate big rigs inside Yellowstone National Park. We were in loop E, which had concrete pads and picnic tables. Every site in loop E is a pull through, which is nice. However, there is zero shade and it gets windy. It didn't seem to bother some of the other campers since people were still eating at their picnic tables, but I found it tedious to combat the wind whilst trying to have dinner the one night we did attempt to eat outside. Campfires and propane fire pits are not allowed so you will find zero campfire rings in this campground. You can have either propane grills or charcoal grills, but they have to be kept within the RV/trailer or tow vehicle at night. Nothing should be left outside at night due to the possibility of curious bears that come looking for food. We played it safe and locked up everything during the day when we weren't there and at night. Just outside the rv park is a general store with souvenirs, small grocery, camping gear, and deli. There's also a gas station and rv/auto parts store. Across from that is the Fishing Bridge Visitor's Center. Fishing Bridge is located centrally in the park on the east entrance road. The website says cell service is spotty, but I had no issues with Verizon and had decent service in the rv park and surrounding Fishing Bridge area as well as the other main attraction areas in the park (Old Faithful, Canyon Village, etc.) Basically, if there were amenities--hotels/lodges, gas stations, campgrounds--there was cell service in and around that area. There was little or no service between those areas. We stayed 4 nights, Monday-Friday, and even though there were signs that said the park was full, I always saw empty spaces, at least in loop E.
