In northwest Marin county. A big wide scenic beach with a few picnic tables, some kite surfers, miles of wide open sand, sand dunes and a leash free playground for your dogs! There's a $5 fee at the parking lot. Lawson's Landing has a small general store and a decent little cafe with good clam chowder. Check the weather first and pay attention to the wind predictions. Light winds are fine: 5-10, 5-15, it's all good, but if you see 20's and up in the weather report, plan accordingly.
