Carquinez Strait Regional Shoreline, Regional park at Carquinez Strait, California.

Carquinez Strait Regional Shoreline is a regional park stretching along the southern shore of the strait for about 1,400 acres with coastal hills rising several hundred feet. The landscape combines open grasslands, oak woodland, and eucalyptus groves that create varied terrain for walking and exploring.

A scenic road was built through the area in 1912, but landslides forced its closure to vehicle traffic by 1983. The roadway has since been converted into walking trails for public use.

The park's best-known route follows the old Carquinez Scenic Drive, a 1.7-mile road the state built along the southern shore in 1912 and later handed to Contra Costa County. Storms and landslides in 1983 tore gaps in it and closed it to cars for good. The county and the park district agreed on an easement in December 2012, and the rebuilt path opened in autumn 2014 as the George Miller Regional Trail, named for the congressman who secured $3.5 million in federal funds.

The park has two separate staging areas where visitors can park and access different walking routes. Be ready for hilly terrain, exposed ridges, and changing weather conditions that can shift quickly throughout the day.

The 1.7-mile Carquinez Scenic Drive, built by the state in 1912, was closed to cars after storms and landslides tore gaps in it in 1983. Contra Costa County then turned the abandoned road into a trail, opened in autumn 2014 and named for former U.S. Representative George Miller, who helped secure $3.5 million in federal funds.
