Niles Canyon is a canyon in the San Francisco Bay Area formed by Alameda Creek, known for its heritage railroad and silent movie history. The canyon is largely in an unincorporated area of Alameda County, while the western portion of the canyon lies within the city limits of Fremont and Union City. The stretch of State Route 84 known as Niles Canyon Road traverses the length of the canyon from the Niles district of Fremont to the unincorporated town of Sunol. Two railroads also follow the same route down the canyon from Sunol to Niles: the old Southern Pacific track along the north side, now the Niles Canyon Railway, and the newer Union Pacific track a little to the south. At the west end of the canyon are the ruins of the Vallejo Flour Mill, which dates to 1853.
The community of San Antonio Valley, also called San Antonio or San Antone, is located along the Diablo Range in eastern Santa Clara County, California. The locale is bordered by Alameda County to the north and Stanislaus County to the east. The sparsely populated area is located at the junction of San Antonio Valley Road, Mines Road, and Del Puerto Canyon Road. The area includes the San Antonio Valley Ecological Reserve, a 3,282 acre nature preserve created by a Nature Conservancy purchase of land from local rancher, Keith Hurner, and known for its herd of tule elk.
Alameda Creek is a large perennial stream in the San Francisco Bay Area. The creek runs for 45 miles (72 km) from a lake northeast of Packard Ridge to the eastern shore of San Francisco Bay by way of Niles Canyon and a flood control channel. Along its course, Alameda Creek provides wildlife habitat, water supply, a conduit for flood waters, opportunities for recreation, and a host of aesthetic and environmental values. The creek and three major reservoirs in the watershed are used as water supply by the San Francisco Public Utilities Commission, Alameda County Water District and Zone 7 Water Agency. Within the watershed can be found the highest peaks and tallest waterfall in the East Bay, over a dozen regional parks, and notable natural landmarks such as the cascades at Little Yosemite and the wildflower-strewn grasslands and oak savannahs of Sunol Preserve. After an absence of half a century, ocean-run steelhead trout will soon be able to return to Alameda Creek to mingle with remnant rainbow trout populations. Completion of a series of dam removal and fish passage projects, along with improved stream flows for cold-water fish and planned habitat restoration, will improve and restore habitat conditions for migratory fish. Steelhead trout and Chinook salmon will soon be able to access up to 20 miles (32 km) of spawning and rearing habitat in Alameda Creek and its tributaries.
Arroyo Mocho is a 34.7-mile-long (55.8 km) stream which originates in the far northeastern corner of Santa Clara County and flows northwesterly into eastern Alameda County, California. After traversing the cities of Livermore and Pleasanton it joins South San Ramon Creek to become Arroyo de la Laguna, which in turn flows to Alameda Creek and thence to San Francisco Bay.
Hospital Creek, originally Arroyo de Ospital, or Arroyo del Osnital is a tributary of the San Joaquin River draining eastern slopes of a part of the Diablo Range within San Joaquin County.

It became a well established inland route, and an alternative to the coastal El Camino Real trail used since the 1770s in the period.
Corral Hollow, formed by Corral Hollow Creek, is a canyon partially located in Alameda County, with parts in San Joaquin County, 6.5 miles (10.5 km) southwest of Tracy, California. Corral Hollow Creek, formerly El Arroyo de los Buenos Ayres, from its source 1.9 miles (3.1 km) north of Mount Boardman, flows north 1.89 miles where it turns to flow west-northwest 8.5 miles (13.7 km) then turns abruptly east in the vicinity of Tesla to flow 5 miles (8.0 km) east where it turns again in a northeasterly direction for 6 miles (9.7 km) to the Delta-Mendota Canal in the San Joaquin Valley.

Corral Hollow Pass, originally Portezuela de Buenos Ayres is a low mountain pass in the Diablo Range southeast of Livermore, in Alameda County, California. This pass, at an elevation of 1600 ft, was the point where El Camino Viejo crested the range, leaving the Arroyo Seco watershed in the southeastern part of the Livermore Valley and dropping down a deep canyon into Corral Hollow near the former mining town of Tesla. The road then continued eastward along Corral Hollow Creek into the San Joaquin Valley. Today County Hwy J2 follows this route. This is a popular alternate route to Interstate 580 during rush hour.
Zapato Chino Creek formerly known both as Arroyo de Las Polvarduras and Arroyo de Zapata Chino, is a creek in Fresno County, California. Its source is in Zapato Chino Canyon on the east slope of Mustang Peak in the Diablo Range. From there it runs northwest through Zapato Chino Canyon, in the Krayenhagen Hills, then passed across Pleasant Valley to the Guijarral Hills, then east through the Polvadero Gap, then runs northeast to its confluence with Los Gatos Creek. It usually dissipates in the San Joaquin Valley, 11 miles east of Coalinga. However it reaches Los Gatos Creek in years of heavy rainfall.

Arroyo Valle or Arroyo Del Valle is a 36.4-mile-long (58.6 km) westward-flowing stream that begins in northeastern Santa Clara County, California, and flows northwesterly into Alameda County where it is dammed to form Lake Del Valle. After that Arroyo Valle is tributary to Arroyo de la Laguna which in turn flows into Alameda Creek and thence to San Francisco Bay. In the past, the Arroyo Valle had a significant steelhead migration; however, degradation of the stream in the latter half of the 20th century has decimated this anadromous fish population.
Arroyo Bayo is an 8-mile-long (13 km) perennial stream which flows northwestly along Mount Hamilton Road east of Mt. Hamilton in the Diablo Range. It is part of the southern Alameda Creek watershed in Santa Clara County, California.
