Raven cliff is a great place to walk in Camp. There are tons of sites along the path to the falls and in a back area by the parking lot. You could go with a large group or a small tent and I feel like there would always be a site available. Keep in mind there are restrooms at the parking lot but no other facilities. I did not have cell phone service while I was there. There is a lot of bear activity here, so make sure you don't have any food or toiletries in your tent. We saw a cub and a mom while we were there. Many sites are by the river, it is quiet and nice to be able to walk to the falls from your site. Even in the summer, it was nice and cool by the river.
Red Red Top is one of my favorite spots when I need a quick Wilderness cat away from the city. It is always well taken care of, and the sites have easy access to the lake which is nice for sunrise, sunset and relaxing in a hammock. The sites are clean and easy to find, and the campground is only accessible with an access code in the evenings.
