Mark West Creek Regional Park & Preserve Preview Days

November 9, 2019 from 9:00 AM 3:00 PM

If you signed up for the shuttle service, please plan to drive to the park instead. We will not have shuttles available on Dec.14.  We apologize for any inconvenience.

Explore the future Mark West Creek Regional Park & Preserve during monthly “park preview” days from 9 a.m. to 3 p.m. on the second Saturday of each month beginning July 13, 2019. You’re invited to hike 7 miles of trails and roads on some of the 1,200 acres making up the parkland.

Mark West Creek Regional Park & Preserve features a rugged, natural terrain that includes a mix of grasslands, chaparral, oaks, Douglas fir, redwoods and riparian areas along Mark West, Porter, and Mill creeks. Sonoma County sought to conserve the area because of its natural resources, significant wildlife habitat, scenic vistas, and its potential for outdoor recreation and education.

The Sonoma County Ag + Open Space purchased the properties making up the park and preserve over a period of 15 years and transferred the land to Regional Parks in late 2018. Regional Parks is undertaking a three- to five-year master planning process that will culminate in the park opening daily.

Regional Parks is hosting monthly park preview days to provide initial public access to the land. Parks staff and volunteers will be on site to help orient visitors and offer information about the parkland.

The park and preserve entrance is located at 3000 Porter Creek Road, west of Safari West. Road signs will mark the property entrance on park preview days, which are the only days the property is open to the public. Parking is limited, so please RSVP. If you are attending with friends or a group, please carpool.

Bring your own water. Water is not available on site. Dogs on leash are allowed. Bicycles and horses are not permitted at this time.

    Approximately 1 mile of new trail meets proposed federal accessibility standards to the extent possible at this time. This unpaved trail connects the parking area to an existing network of ranch roads and trails, where some sections do not meet accessibility standards. Accessible parking spaces (unpaved but leveled and signed), picnic tables, portable restrooms and hand-washing stations also are available. When arriving, ask staff to direct you to accessible parking.
