Alot of campsites in a relatively small area. A couple of teepees if you're so inclined. Nevertheless, you do feel like you're alone in your campsite if you don't pay attention to the others near you. Bathrooms, showers available. Easy to access the bay if you want to kayak or canoe.
A pay by the day and rangers will enforce. Dress in layers. Nestled in with large pieces of driftwood trees acting as berms between your campsite and the beach sand. Short walk to the ocean or mouth of the Mattole River. Seismic area, so the sand on the river is never the same if you go more than once a year. Bathrooms near the campground. No showers. No electricity. The starting point to hike the Lost Coast.
Camp right above the river. Most likely, you will have a campground to yourself. Not too far from a glacier lake, so good for hiking. Bears not too far away.
Find a spot and enjoy. No cell service. BOLO for bears and possibly wild boars. Trinity River access, so enjoy swimming, kayaking if the rapids aren't too intense. Pan for gold if you're so inclined. A wonderful area to reconnect with nature.
