Awesome for families
Pros: Awesome, family and dog friendly campground. Be sure to checkout the hiking trails (fairly easy even with small children) as the redwood grove is pretty magical. Our whole experience was great. The junior ranger program and nightly events for families helped keep the kids engaged in the camping experience. Park rangers hosted guided hikes, nighttime stargazing (with telescopes), and nightly campfires. There are showers which is a plus for long stays. There are nearby stores on 128 for provisions (east - Lemmons Market; west - Navarro General Store) as well as several fruit stands.
Cons: There's quite a bit of poison oak, be aware of where you are walking. When we visited in late summer the river near the daily access area was somewhat dried up (flowing like a small creek) and had very little shade.
