Betwn Sacramento - Redding - RV Park Recommendation/

:h Lower Salt Creek Shoreline Campground - Lakehead, California

Shasta-Trinity National Forest

Only been through that area once ('97), we did an overnight by Lake Shasta. Not sure of the name of the site. More or less a parking lot campsite if I remember correctly.

Edit PS: Just looked on a map, looks like all the above are above Redding & you want some below.

Have you looked around the Sacramento National Wildlife Refuge Complex, located approximately 90 miles north of the city of Sacramento:
