Spent 10 days there a couple years ago. If you can get a site and you need hookups, I suggest you make your reservation asap. They go fast. Fishing Bridge CG is nothing special to look at, but it is well located to visit many parts of a VERY large Park. We have a 30 ft. class C so when we made our reservation we picked a site a bit bigger; worked well. We really didn't spend much time at our site because we were out and about every day, almost all day. I believe all the other campgrounds in the Park are dry camping. Good luck, and have fun.
By the way, it is run by a concessionaire so you will not get the NPS camping discount.
