Marin Headlands, Marin County, CA
Just across the Golden Gate Bridge from San Francisco, the Marin Headlands offer shoreline views, crashing surf, and a surprising wildness. Join the parade of cars winding up twisty Conzelman Road to Hawk Hill, but don’t stop there. Drive a bit farther to the beach parking area on your left, and you’ll see signs for the trail to Black Sands Beach. Another great spot is the Tennessee Valley Trail, which winds 2.2 miles (one way) past rolling hills toward a secluded beach awash with green and black basalt pebbles.
Sellwood Riverfront Park, Portland, OR
On the east bank of the Willamette River at Sellwood Riverfront Park, picnic tables are perfect placed, and the lawn is an ideal spot to spread a blanket. The park is popular with dogs, and if you want to take a walk, the wetland at the northern edge makes a pretty loop.

Though it was installed more than 30 years ago, few outsiders know about it, so it’s usually quiet.
