Yellowstone Grant/Madison CG's

Grant and Madison campgrounds say max of 30' for trailers in back-in sites. After making reservations in May, I just picked up my new 5th wheel and found it is 30'6".

I've looked at pictures of the campsites and can't imagine another 6" is going to be a deal breaker but if anyone has camped there I'd certainly appreciate opinions. I can't determine if 30' is the length of the site, or if it's a measurement with the trailer's wheels backed up to the log stop and the rear of the trailer hanging over.

I called the reservations center today and was assured they could work me in a spot, but I'd hate to drive for 3 days to find it's a no go.

Any help appreciated.

    My Grayhawk is 30" 9", and I was towing a CRV. I called the campground number and over a few days they found me a 3 night and a 2 night opening,(2 different campgrounds) THAT THEY SAID WOULD FIT my equipment, so no surprises upon arrival.
    I strongly recommend calling, not using the website.
    and Yellowstone was great (only our 5th trip)...


    You did not mention but I'm assuming the 2 different campgrounds you stayed at were Grant and Madison. Were your sites back in or pull through?

    I did make reservations over the phone but the folks I talked with were at a reservation center and not at the campground and basically were repeating what they had been told about the campsites, i.e. 30 feet max.

    If you remember the number where I could actually speak with someone at the Yellowstone campgrounds I would really appreciate.

    There are no measurement police, no one will come around with a tape measure to see if your unit is 30' or 30" 6" or 35' for that matter. If your unit fits in the site then you are good to go so long as it does not stick out into the roadway. I have never seen a NPS cg where the tow vehicle did not have room to pull into the site. Maybe not enough room but close. I had the rangers at Yosemite tell me to park my truck sideways once.

    Not that being said, if you cannot get into the site then you are out of luck, no refunds and they will not find you a different site.


    I appreciate your reply, but it does not answer the question. I know they will not measure my trailer, and I know if a vehicle is in the road you will be asked to leave.

    What I'm asking in my OP is if anyone has had experience with actually staying in these campgrounds, and if the sites will actually accommodate anything slightly over 30'.

  • I’ll bet you are close enough for the federal government.
