I did take a drive through video of the Cottonwood campground for you. It rained for two days there and we would have had issues with just solar power alone anyway. I could always bring out the generator for a period before dark to recharge the batteries of course.

There are many hiking trails throughout the park. Some very long, some short as well. I think you'll enjoy this location a great deal. Medora Campground gets the thumbs down, but the National Park is a big Thumbs up. :)

Since it is further south, it is a popular place. So get there early, Cottonwood Campground, if you want to get a spot. You may even try calling ahead to see if you can get an idea of how full they are.

Cell service with Visible and Verizon: 1 to 2 bars at Medora Campground. You may get no cell service at all inside the park.

If you must, Medora Campground will do. It is a very busy park, even early on in the season when we were there, but certainly no where near booked. Call ahead if in doubt.
