Review:

We have not stayed at Fishing Bridge (it has not been available when we’ve tried to book), but we drove through and checked it out. This is the only campground in Yellowstone with hookups.

The sites in LOOP E are pull through, level asphalt and designed for big rigs.  Not a ton of trees, but very nice sites. 

Importantly, we found out you can book one year in advance at Fishing Bridge, and we will do that in the future. The location is great, close to Yellowstone Lake and Hayden Valley. 

There is a large central laundry/shower facility (very busy in the evening) next to the registration/store area.

We will definitely stay here next time we visit Yellowstone.
