It's that time of year again—the unofficial start of summer kicks off this weekend! Make it official with any of these sizzling good times. 

Peters Creek Portola Redwoods

Portola Powerhouse: Hike to the most pristine grove of old-growth redwood trees in the Bay Area. The 13-mile (round-trip) walk to Peters Creek in Portola Redwoods State Park takes most of the day, but time flies when you're among old friends.

Eagle Eyes: Sure, the main summit of Mount Diablo offers one of the best views in the state, but if you’d rather hike than drive to a summit, lace up your boots for the mountain’s spectacular—and less-traveled—Eagle Peak.

Commemorative Stamp: For flowing and novice-friendly mountain biking in Tahoe, point your fat tires toward Commemorative Emigrant Trail a few miles north of Truckee. This singletrack rolls like ribbon for miles through golden alpine meadows and Jefferey Pine forests, with a water destination reward!

Pacifica Pedal: Two wheels, three beaches, hundreds of wildflowers, and a wine-stop option. That’s what you'll have on this easy 8-mile (round-trip) bike ride in Pacifica.

Isle of Wines: Not all of the Bay Area's most interesting wines are experienced amidst rolling latticed vineyards and opulent tasting rooms: some are enjoyed in giant warehouses on an island.

Early Riser: Watching the sun set over the Golden Gate Bridge is awesome, but there's another way to be amazed at the beauty of the Bay Area's most famous landmark: check out a sunrise via a short walk on a prime part of Lands End's Coastal Trail.
