This is a wonderful area to stay and explore for at least a few days - lots of great hiking - easy to challenging depending on your level. There's a variety of campgrounds in Big Basin, along with cabins as well, if so preferred. The staff at the park were excellent in providing good information for hikes in the area and the campgrounds were great - all except for the tenacious family of raccoons that were determined to get free handout.
This is an absolutely stunning beach area that seems to go on forever, with a rustic but very pleasant campground with limited spaces. The campground is situated close enough to the beach to hear the pounding waves, but protected by a sand bluff that blocks wind that might come from off the water. It would have been great to spend more time here and take in the beauty and ruggedness of the place, but having the opportunity to see this place first hand, after a friend recommended it, was sufficient so that I can definitely plan a longer trip next time. While it is a bit of a trek off the 101 to get to Mattole, as it's about 40 miles on very twisty, narrow, steep and not the smoothest of roads that rise and fall with the geography. Most definitely worth the drive - especially on a motorcycle, but probably not so much with an RV.
