The Dumbarton Bridge, which has a bike lane. This picture was taken from Fremont, looking west to the peninsula.
The hills east of Fremont. This is Walnut Ave., just past the California School for the Deaf.
Mission and Monument Peaks. This is also from Walnut Ave., looking south.

A creek cascades down the steep walls of Niles Canyon.
A vineyard and the hills southeast of Livermore.

Rows of windmills line many ridge-tops along Altamont Pass. There are more than 7000 windmills in the area.
The California Aqueduct at Altamont Pass. In the background, windmills stand in neat rows.
Just east of its summit, Corral Hollow gets fairly steep. You can see the incline of the road cut into the hillside on the right.
This is Palomares Road, which runs between Niles Canyon and Dublin Canyon. Most of its length is in a valley, with a few houses on both ends, and ranches and a hill in the middle.
This is the upper end of Mines Road, just north of the Santa Clara County border. As you head toward Livermore, the creek follows the bottom of the canyon, while the road clings to the canyon wall, several hundred feet up.
