01
Best riverside escape
Caswell Memorial State Park
Near Ripon, South Of August • Shady Riverside Nature Park • Best Close-To-Town Escape
A rare patch of Central Valley river forest with easy, shady trails along the Stanislaus River.
When August heats up, locals head to Caswell for the shade and the water. Short, mostly flat trails wind through dense oak and cottonwood forest, with frequent side paths that drop down to the river’s edge. Go early on summer weekends for easier parking and quieter stretches of sandbar to yourself.
02
Top birdwatching walk
Cosumnes River Preserve
North Of August Near Galt • Wetlands And Boardwalk Preserve • Best For Wildlife Spotting
Gentle loops and boardwalks through wetlands and oak woodland, packed with migrating birds in cooler seasons.
If you like your hikes slow and observant, the Cosumnes River Preserve is an easy win. The trails are mostly level and short, but the birdlife, seasonal wetlands, and oak groves keep it interesting year-round. Bring binoculars, and plan a fall or winter visit if you want to see huge flocks of sandhill cranes and waterfowl at sunset.
03
Iconic summit day trip
Mount Diablo State Park
East Bay Hills Near Clayton • Classic Bay Area Summit Park • Best Big-View Climb
Steep, rewarding trails climb to a summit where, on clear days, you can see across much of Northern California.
Mount Diablo is the closest true mountain feel you can get in a day trip from August. Trails like the Mitchell Canyon or Summit routes mix chaparral climbs, rock outcrops, and wide-open views over the Delta and Central Valley. Start early, carry plenty of water, and expect exposed, sunny climbs that pay off big at the top.
04
Rolling hill classic
Brushy Peak Regional Preserve
Altamont Pass Near Livermore • Rolling Foothill Open Space • Best Spring Wildflower Walk
A network of ranchland trails circling Brushy Peak with wide valley views and steady but manageable climbing.
Brushy Peak feels a world away from August’s flat streets, even though it’s just over the Altamont. The main loop climbs gradually through oak-dotted grasslands, with views of wind turbines, the Livermore Valley, and back toward the Central Valley. It’s at its best in late winter and spring, when the hills turn green and wildflowers line the trail.
05
Best full-day mountain getaway
Calaveras Big Trees State Park
Sierra Foothills Near Arnold • Giant Sequoia Forest Park • Best Family-Friendly Adventure
Well-marked forest trails wind through groves of giant sequoias, with cooler mountain air than the valley below.
For a true change of scenery, point the car toward the Sierra and spend a day wandering among the sequoias. The North Grove loop is an easy, well-signed introduction, while longer routes in the South Grove feel wilder and quieter. Pack layers and a picnic, as the elevation brings cooler temperatures and makes it easy to turn a simple hike into a full-day escape.
