Bounded by Mountain View and East Palo Alto, the 1,940-acre Baylands Preserve is one of the largest tracts of undisturbed marshland remaining in the San Francisco Bay. Fifteen miles of multi-use trails provide access to a unique mixture of tidal and fresh water habitats. It is an important habitat for migratory shorebirds and is considered one of the best birdwatching spots on the West Coast. (Best to drive HERE at TERMINAL BLVD in Mountain View to park and start your walk).

Official name: “Enid W. Pearson–Arastradero Preserve” is a wonderful place to un-plug in Silicon Valley! It offers a mixture of rolling savanna grassland and evergreen forest views. Wildlife abounds on the preserve and it is not uncommon to see deer, bobcats, coyotes, and many varieties of birds. Each area of the preserve has something different to offer, whether it is a view of the bay, a quiet walk through the grasslands, or a snooze by the lake. (Arastradero Lake is a twenty minute hike from the parking lot and is open all year to fishing. All California Fish and Game rules apply. Boats, flotation devices, and swimming are not permitted). The trails take one from an elevation of 275 feet in the northeast to 775 feet in the southwest.
