Pros - you are in the middle of the Sequoias, near hiking, kayaking, etc. Beautiful river nearby; pretty easy in and out for small-ish RVs. Hard to beat the location.
Cons - some road noise from Hwy 4, trucks going by were sometimes pretty noticible; some toilets and showers were pretty nice, some pretty beat up. Inconsistent pricing on the showers.
Overall impression - beautiful location, good for trailers, if you can get a flat spot a little farther away from the highway it would be better.
Pros - close to Mendocino and Fort Bragg; toilets and showers well-maintained; campground itself is beautiful, with some sites that have close neighbors, and some that are more isolated. Dump station. Beach across the street from the entrance.
Cons - sites have varying degrees of flatness, so if you are in a tent you may have a challenge finding a flat enough spot; due to a temporary bridge and narrow roads to the upper campgrounds, towing anything above a small (<20') trailer might be a challenge for less experienced RV folks (like me!).
Overall takeaway - bring a tent or small rig, call or get reviews for the flattest sites (52 looked good), and enjoy the beautiful surroundings! We stayed in site 45, which backs up to the redwoods.
