My daughter and I were on a road trip from Long Beach, CA to Long Beach, WA this April and visited with friends in nearby Murphys. They recommended Big Trees State Park, so we swung by to see if we could nab a spot to camp; sadly, the campground was still closed for maintenance—tree clearing, parking lot paving, etc. 

We were able to take the walking tour of the North Grove and snuck a peek at the campground. The entire park is beautiful and well-maintained. We met an off-duty ranger while on the trail; she was giving her elderly father a personal tour. Despite, she spent some time sharing with my daughter points of interest and interesting facts/history. The on-duty rangers were equally as helpful and friendly.

We will be back to camp as the spots were really well-spaced and level; the campground had clean, modern facilities and great access to the trails. Absolutely gorgeous.
