Yellowstone Bridge Bay

Finally got through to the rez center. The answer was that all vehicles must fit in the space. There are a few forty foot spaces but most are 30' or smaller. There is no external parking for the truck.

I believe that Yellowstone campgrounds are very picky. We stayed at the Fishing Bridge campground a few years ago with a 5th wheel and truck. We were able to park the truck and trailer in the spot disconnected with some room to spare. I don't recall the site length, but I know there was no room outside of the pad to park and no parking anywhere else. I'm surprised you can book a spot for this year. Usually they are booked up all season long.

Thanks to all. I have tried calling them for three days. Busy signal non-stop.

We were there in 2015, with our 29' Class C, dolly & toad, Site 60 IIRC, it was a barely long enough pull through, after unloading the toad, we parked it in front of the MH, had to unhook the dolly & re-arrange it so it fit on the pad, as we were specifically told that ALL equipment MUST fit on the pad.
As others have said, there were bigger sites, with Class A's,and long 5'ers. A call directly to the cg will be a big help.

We've camped at Bridge Bay, but it was at the end of the season and we just drove in, no prior reservations. At the time we had a 25' travel trailer. They assigned us a roadside site, where you park parallel to the road. There were back in sites and we saw several fifth wheels there, big ones. If you look at pictures online of this campground, you'll see big Class A's in the area up front. Call them.

*Note - sign up at Campendium.com. It's a great reference site. Search for Bridge Bay and you'll see 50 + photos of the CG.

RV Guests at Bridge Bay Campground

RVs up to 40’ long may be accommodated in pull-through and back-in sites. The sites may not be level, so campers should plan accordingly.

30 feet combined is probably right for that campground. I think it is designed for tents or pop-ups.

Best bet is to call the reservation line directly...ask them that question.
