Quiet with easy access
This campground is in a remote part of the mountains but is very easy to find. My niece and I stayed here for 1 night recently and completely enjoyed the stay. You get a view of the mountains from the road, there is lots of hiking to be found, and plenty of water to enjoy hearing. One of the trails in the park takes you to a waterfall but first you must cross a cool log bridge over a rocky creek.
This campground is located in bear county and they do a great job making sure that you are aware of this fact and know what to do. They provide bear-proof garbage throughout the grounds and every few campsites, has a bear-proof box that you can keep food in if you aren't traveling by a hard-shelled vehicle (their words). Bathrooms are readily accessible and are kept clean. They also have a place to clean your dishes outside the bathrooms so that all scents stay away from your campsite.
The night we stayed, it was very windy. Be prepared for this as the area is full of trees, it sounds like roaring at times even though it wasn't doing much at all. It wasn't stormy, just extra windy that night. This could be a little scary to kids who aren't prepared.
