Informative panels provide historical context for the former salt production ponds that were built into the fragile bay wetlands in the 19th century and are being partially restored to more natural wetlands in the past few decades.

An excellent paved section of the Bay Trail circles around Foster City along the bay, not the shortest but probably the fastest and more interesting route than the alternative along roads branching off here through the center of Foster city.

90 percent of San Francisco Bay's former wetlands have been destroyed by development, this one for the eponymous offices for Larry Ellison's company, who wants to be a famous sailor (judging by how he bought a 'victory' at the America's Cup), but apparently doesn't care much about protecting the waters he's sailing on.

The 15-mile Crystal Springs Regional Trail is one of the best mostly paved bike trails with few cars in the Bay Area. It spans from San Bruno to Woodside and is routed along three gorgeous lakes and connector links amid riparian woodlands. On Sundays, you can combine the San Andreas and Sawyer Camp segments to south of Highway 92 to Cañada Road, which is closed to cars for Bicycle Sundays (See https://www.komoot.com/tour/11413421) Speed limit: 15 mph, difficult for high-end road bikes to stay below, so bring a bell: some hikers stand and talk in the center of the trail ;-) San Andreas segment: From Skyline Boulevard south of San Bruno Avenue the trail drops to the head of San Andreas Lake, with pretty views across to the west of the wilderness slope of Montara Mountain. It rides along the lake 2 miles to an access point near Larkspur and 0.6 miles to another (at Hillcrest) where it connects to the Sawyer Camp segment. Sawyer Camp segment: This is a gorgeous, easy bike ride, where you drop 400 feet over the span of 6 miles to Crystal Springs Dam. The route descends into riparian woodlands for 2.5 miles to Jepson Laurel picnic grounds, then runs along Crystal Springs Reservoir for 5.2 miles. You can continue another 1.7 miles to Cañada Road for Bicycle Sunday (no cars). Cañada Road/Crystal Springs segment: South along Upper Crystal Springs Reservoir for 2.1 miles to the Pulgas Water Temple. It continues another 2.1 miles past Filoli Botanical Center and Phleger Estate to Edgewood Road http://sfgate.com/outdoors/sundaydrive/article/Crystal-Springs-Trail-links-lakes-woodlands-4723374.php http://parks.smcgov.org/crystal-springs-regional-trail
