I highly recommend checking out the Coos Canyon Campground. The lot spaces were decently sized, and ours had water and electricity. They have a cute little general store that you can get some supplies in, along with clean showers and restrooms. You can bring in your own wood (which I recommend) or you can buy some from the store (which was a little pricey). We spent two nights there and could have spent an entire week. The canyon itself had tons to explore including rock climbing, cliff jumping, swimming, fishing, a cute little sandy beach for the littles to play on, and so much more. We brought our bikes and had fun riding around the campground. This being our first time there, I would definitely go back!
