Cooper Creek is a great, smaller campground to choose when the popular nearby spots fill up with anglers. For some reason, this spot is not as in demand as the Russian River campground, despite having many of the same amenities.
This campground is great for group camping trips, as each site is rated for 8 people and a few can have up to 12. There are many ada-acessible sites to choose from as well, which was a great help when bringing along family in need.
The gravel roads can sometimes mean backing-in is a bit more strenuous than other paved campgrounds, but if you're camping in Alaska, you probably already know how to reverse park a camper! Picnic tables were always well maintained, and the deep firepits came in handy for our large fires. They even have grills built in!
Toilets are well maintained, but we always had to supply our own method of handwashing - hand santizer, in our case to leave as little trace as possible.
Don't forget to bring your fishing poles (get that permit first!) and keep an eye out for bear activity.
