I'm guessing I've cycled Yellowstone two dozen times or more.
My first trip was back in 1987 when I was a North Carolina boy.
I was amazed - - - and I just happen to live in Wyoming now.
Yes, it can be busy, but if you ride super early, it's not.
And you get to see all the wildlife.
Note to those unfamiliar with Yellowstone NP:
All of the campgrounds except Slough Creek have hiker/biker campsites.
Which means you can ride in in the late afternoon/evening and still get a site.
(Fishing Bridge is for RVs only.)
A) My favorite large campground is Canyon - right in the middle of the park.
The hiker/biker campsites are ona loop with a few down in the ravine - isolated.
Isolated is good, unless you get nervous about grizzlies, but there are bear boxes.
There are showers and a laundrymat, a cafeteria, a camp store, and a visitors center.
Great ranger programs every evening.
And some of the bst hiking along the rim of the Grand Canyon of the Yellowstone.
98% of visitors don't go more than 100 yards away from pavement.
Be sure to hike out from Artist Point of the South Rim.
B) My favorite small campground is Pebble Creek - near the Northeast Entrance.
Very, very few cyclists come this way, but it's worth it.
About 15 years ago the camp hosts created the hiker/biker site.
It's close to the host site and has one tree.
The hosts have always been especially nice to cyclists.
This is a basic campground with pump water and vault toilets.
The hiking in the Lamar Valley is exquisite - more open terrain.
Wildlife, wildflowers, and wolf howls in the evening if you are lucky.
