Fishing Bridge's own employees call it Walmart with hookups. Not the best but who cares it is just a sleeping spot. The road to Canyon Village from Fishing Bridge (Hayden Valley I think) is where we saw the most wildlife. We had severe rainstorms and the roads and many campsites puddled considerably. I always tell the truth about the length of my trailer when making reservations but I think I might embellish some with Fishing Bridge. My site was too short for my trailer. Overall I would stay again just for the location and full hookups. Have fun on your trip.
