Multi-Use Trails

Our objective is to see the North Bay criss-crossed with a network of  trails which can be used for bicycle, hiking and/or equestrian recreation. Walk out of your green lodging and onto a trail!

Jenner-to-Armstrong Trail

This proposal is to link the California Coastal Trail near Jenner with Armstrong Redwoods Reserve with a hiking/equestrian trail. The proposed route runs through the Jenner Headlands, across Austin Creek and up East Austin Creek following the historic narrow gage Magnesite Mine Railway right-of-way into the Austin Creek Recreation Area which already connects to Armstrong Redwoods.

Goal: Jenner to Armstrong Woods

Status: Route researched, ownership of historic Magnasite Railway researched, interested parties organized.  Key parcel acquired by Wildland Conservancy.  Easements offered.

Since 2008 EcoRing has been encouraging Marin and Sonoma County officials to convert the historic right-of-way of the narrow-gage North Pacific Coast Railroad (built in 1871) to a multi-use trail where possible.

The historic narrow gauge NPC Railroad no longer runs steam trains from Sausalito to Cazadero. But much of the original right-of-way is already multi-use trail in Marin County.  We propose extending and connecting these trail segments all the way to the Russian River in Sonoma County, on the original right-of-way where possible.  We have researched the route and determined that the majority of the right-of-way is owned by federal, state and county government. Part of this route could double as California Coastal Trail along Tomales Bay.

Goal: Sausalito to Cazadero linking to the Russian River Valley Trail and the Jenner-to-Armstrong Trail

Status: Portions of the original rail route are already bicycle or hiking trail predominately in Marin County. These include a stretch from Sausalito to the south end of the  Alto Tunnel in Larkspur, a segment from the North end of the Alto Tunnel in Corte Madea  to San Anselmo and a lengthy segment in Samuel P. Taylor State Park. Several portions of the original rail route are bicycle-friendly rural roads in Sonoma County including Occidental-Camp Meeker Road, Moscow Road and Cazadero Highway. A portion of this trail from Sausalito to Baltimore Park is included in the Marin County Bicycle Coalition’s North South Greenway program.

EcoRing has started a branding campaign to raise awareness of the potential for this trail. We have made presentations to service groups and provided history tours of the original right-of-way. In cooperation with the Occidental Community Council we have researched, designed and installed a kiosk display located on the right-of-way in front of the Union Hotel in Occidental.  We turned over our property research on the portion of the right-of-way near Monte Rio to Sonoma County Regional Parks.  Parks subsequently purchased 500 acres of land containing the right-of-way and plans a class I trail along the right-of-way.  We are building a coalition of businesses and individuals to press both Marin and Sonoma Counties to link and complete this trail.

Russian River Pathway

For safety reasons alone, bicycle and pedestrian travel between Steelhead Beach in Forestville and Guerneville should be diverted to a combination of multi-use trail and bike route roughly following the Russian River but apart from dangerous River Road.  Such a trail is now in the Sonoma County General Plan (something that we pushed for).  We researched potential routes and toured them with our former County Supervisor.  We hope that one day this trail will extend from Cloverdale in northern Sonoma County to Jenner connecting to the Coastal Trail. Here is the latest on this trail from the Sonoma County Parks:  Click here.

Goal: Cloverdale in northern Sonoma County to Jenner connecting to the Coastal Trail

Status Update .  A  Draft  of the Lower Russian River Trail Feasibility Study was presented to the Sonoma County Board of Supervisors during their meeting in January during which the Board and public provided comments on the draft study. On February 11, 2020, the Board of Supervisors accepted the findings and recommendations contained in the Final Lower Russian River Trail Feasibility Study.

Sonoma County Regional Parks will meet with property owners over the next five to ten years to OBTAIN PERMISSION to use their private property for trail construction. Initial conversations may result in Agreements in Principle. As projects move closer to construction, SCRP will negotiate right-of-was agreements, including easements, and trail use or licensing agreements. Please support this project by contacting your Sonoma County Supervisor

Valley of the Moon Trail

EcoRing has advocated a multi-use trail from the city of Sonoma to Glen Ellen, Kenwood, Oakmont and Spring Lake Park in Santa Rosa following, where possible, the original Southern Pacific rail line. This route could connect County and State Parks and run near wineries and restaurants in the Valley of the Moon.  A Santa Rosa to Sonoma trail has been included in the Sonoma County General Plan but the proposed route the trail along dangerous Highway 12, a wholly unsatisfactory route that places cyclists next to high-speed traffic, noise and exhaust.  EcoRing’s proposed route is safer, more scenic and connects easily to Spring Lake and Santa Rosa’s Southeast Greenway.

Goal: A trail linking the City of Sonoma to Spring Lake Park in Santa Rosa.

Status:  The County is moving forward with their Highway 12 route.  There reason for not adopting the Southern Pacific route is that the right-of-way has been lost.  We believe that, over time, parcels and easements can be reacquired.  We are organizing public support for the alternate route.

California Coastal Trail

EcoRing supports the efforts of CoastWalk to complete the California Coastal Trail especially through Marin and Sonoma Counties. This includes sections through the Jenner Headlands, near Bodega Bay and along Tomales Bay where it would coincide with the Sonoma Marin Adventure Trail.

Goal: Complete train from the Gualala River to Bolinas Bay.

Status:  Sections of the trail in Sonoma County have been completed: between Goat Rock and Wright’s Beach Campground, between Bodega Bay Bell Tower and Salmon Creek, and Doran and Westside Regional Park to Doran Beach.  Another section is planed for the Bodega Bay waterfront and along the Jenner Headlands.  The County has started the planning process for trail sections north of Jennner.  EcoRing has lobied for a section in Marin County along Tomales Bay coincident with the Sonoma Marin Adventure Trail.

Southeast Greenway

EcoRing partners with the Southeast Greenway Campaign advocating for conversion of an unused CalTrans right-of-way in Santa Rosa from Farmer’ Lane to Spring Lake Park. Additionally we support the extention of the Southeast Greenway  with a multi-use trail connecting to the Prince Memorial Greenway.   Spring Lake trails would connect the Greeway to the Valley of the Moon Trail. EcoRing participated in the Sustainable Design Assessment Team interviews for the Greenway.  We have written letters to the Santa Rosa City Council and CalTrans on the issue and are organizing public support for the trail.

Goal: A continuous Class I trailn from Prince Memorial Greenway to Spring Lake County Park.

Status:  CanTrans has declared the right-of-way surplus property and is negotiating with the City of Santa Rosa on sale of the property.  On July 9, 2019, the Santa Rosa City Council adopted the General Plan Amendment, Environmental Impact Report and Rezoning Plan for the 57-acre SE Greenway property, dedicating 47 acres to open space and parkland and 10 acres to housing. Caltrans would like to sell the property to the City of Santa Rosa, and so the Greenway Partners – Sonoma Land Trust, City of Santa Rosa, and Sonoma Water – have formed an Acquisition Team to work with Caltrans to prepare for a sale of the property sometime in 2020.

Support the Greenway Campaign.

Gravenstien Trail

EcoRing partners with the Sebastopol Trailmakers advocating for conversion of an unused Petaluma and Santa Rosa Railway right-of-way from Petaluma to Sebastopol into a multiuse pathway.  Although the City of Sebastopol and the County of Sonoma have agreed to bike route and path between Petalum and Sebastopol, they have chosen an unsafe route along busy state Highway 116.  Government is still placing cost above safety.  EcoRing continues to advocate for the safer and far more scenic route along the historic rail route.  Some of the route has reverted to private ownership and some has be illegally expropriated by private landowners. This route would connect to the existing West County Trail between Sebastopol and Forestville  and the Joe Rotota Trail between Sebastopol and Santa Rosa to the Petaluma SMART Pathway

Goal: A multiuse trail from Petaluma to Sebastopol on the original Petaluma and Santa Rosa Railway route connecting the Joe Rodota Trail and the West County Trail.

Status:  Sebastopol Trailmakers have researched and mapped the route, contacted adjacent landowners and countered complaints by an small, uninformed but vocal minority of nearby landowners.   We have written letters to the Sebastopol City Council, the County of Sonoma and CalTrans on the issue.  Nonetheless, the County is moving forward with the unsafe route.  We continue to organize public  support for the alternate route.

Contact Sebastopol Trailmakers if you would like to help.
