It is more of a trek to get there than you would think looknig at the minimal distance on the road. The road in is rough. It looks short on the map but you have to go slowly. Please pack your trash and leave no trace. They’re only open for the summer-fall - forest service road definitely not maintained when it snows. Pretty little spot and mostly undeveloped. Although there are firepits I think there is a burn ban still in effect- please respect the burn bans to protect the epic old growth forests!
Little Sandy is way in there, about a 45-60 minute drive with a stream crossing from the main road. A bit past the more popular Big Sandy campground, Little Sandy is much less used and much more primitive. There are no bathrooms so bring your shovels! Firepits available but no picnic tables. It's next to a stream. It's very peaceful and quiet, though during the daytime there were people there just hanging out and a family with kids playing in the stream.
