San Francisco Bay Trail

Difficult to keep on sunny and hot days but there's always a cool breeze and you can observe impressive wildlife .

If you enter at Borregas (SMaRT Station) there is 1) free parking , 2) a porta-potty and 3) a 2 mile loop trail

Beautiful trail to bike or hike . Spectacular views of the Bay and surrounds.

See Map 6 - Bedwell Bayfront Park to Alviso for the full map http://baytrail.org/get-on-the-trail/map-by-number/bedwell-bayfront-park-to-alviso/

Good for birding. Occasionally you can see the Great blue heron, it's a beauty.

The trail is closed from Sunnyvale to Mountain View, around NASA Research building... So sad. :-(

In the summer it smells like wild fennel + low tide + effluent

Not paved but nonetheless pretty good for road biking

Bay Trail connects SF to Oakland - the long way round ;)
