I came here 15 years ago with abalone-diving City friends. I'm not even sure that's a thing any more. Anyway, the campground is still here and it's still awesome. They have spots available when no one else does, and it's the simplest check-in ever: Pay them ($5 off for cash!), they give you a receipt for your windshield and tell you to park at any picnic table/fire ring that's not occupied. The rest of the world seems to get more complicated and bureaucratic, but this is the easiest damn check-in I've ever experienced. Checkout 2pm. Ocean Cove Bar and Grille is a sweaty uphill 3/4 mile walk away. Basic bar food, but great view of the ocean and campground.
Close to Lone Pine, really excellent view of Owens Valley south over dry Owens Lake, The last 2 miles have many brutal diagonal speed bumps, beware!
Saturday of Labor Day Weekend, there were a few sites available at 3pm. I got what I hope is the least nasty. Bless my van for being tall enough to generate its own shade.
What a cool discovery! You leave Route 160 just a little north of the bridge that takes you to Pittsburg/ Antioch and take a bumpy little road along the edge of Sherman Island. The road follows the southern side of the Sacramento River to the tip of the island, where there is a nice county park for the windsurfers. It's roughly where the Sac River meets the San Joaquin River, and it is a great windsurfing spot.
