NorCal Redwood Coastal Camping
Redwood Campgrounds
Del Norte County, Northern California

There are a few special places in California where redwood trees grow right down to the shore, but it is rare. Searching for place to pitch a tent (under the redwoods at the coast) is possible, but a bit harder to find than you might imagine. State Parks usually offer the standard paved camp site. Maybe need to drive dirt roads to find redwood seclusion.

If you are seeking free or dirt cheap, primitive camping on the coast, then LOST COAST CAMPING on the Mendocino border is one option. Or head east, inland to the abundant National Forest. Dirt roads of the Six Rivers National Forest offer old logging roads, creeks, and secluded places to pitch a tent. Campfire permits are needed for dispersed camping, or ‘boondocking’ as some call it.
Dirt back roads can get muddy during the wet season, so know your vehicles capability and if you are unsure, check with the local rangers over the phone (preferably a ‘field ranger’) before venturing out. Remember that rain and mud are the norm, most of the year.
Fog is typical of the region. Enjoy the sunshine – when you can!
