Cook's Beach is found north of Gualala. Drive up Highway One until you reach mile marker 3.14, then turn left at Route 526, which is the old Coast Highway. Just to your right is the entrance path to Cook's Beach. The trail is called Bonham Trail in honor of the Bonham family's easements, which made this access possible.
Below is a view to the south from the overlook on top of the bluff.
And here is a view to the north from the overlook. Since this is a pocket beach it is protected from wind.
It's a kid friendly beach, as well as dog friendly. And it's a perfect place to watch the sunset.
