News Update On The Great Redwood Trail

Few projects now underway in California capture the imagination like the Great Redwood Trail. A planned 320-mile multi use pathway connecting San Francisco Bay to Humboldt Bay, the GRT is steadily becoming closer to reality. We’ve covered the project before in some depth here – today’s post is a call to action and an update on the trail’s recent progress.

Great-Redwood-Trail-Coming-Soon-LogoFixing the Southern Terminus

You might be wondering, why does the trail start at Larkspur instead of the Golden Gate Bridge? Wouldn’t it be fitting for the Great Redwood Trail to begin at the southern tip of Marin, the gateway to the Redwood Empire and the most iconic bridge in America? 

We agree! However, the way the trail was written into law, it ends at the Larkspur SMART station, even though the old railroad right-of-way went all the way to Sausalito.

The elephant in the tunnel

We believe that the GRT should continue all the way to the Golden Gate Bridge. Only by connecting seamlessly to the Golden Gate Bridge and San Francisco would the Great Redwood Trail unlock its full potential. But for this to happen, the trail would need to pass through the Alto Tunnel, the only safe and level route between central and southern Marin. 

We also believe that, if the Alto Tunnel was designated as the future alignment of the GRT, the tunnel would be an even better candidate for competitive state and federal funding. Rather than linking two towns, it would join San Francisco to a 320-mile trail network, further highlighting the need for the tunnel. 

What you can do

The Great Redwood Trail Agency and State Senator Mike McGuire (the father of the GRT) need to hear from us that the trail should extend all the way to the Golden Gate Bridge.

Trail Updates


Though one system, the trail will have (at least) two agencies managing it. Between Larkspur and Cloverdale, the Sonoma Marin Area Rail Transit (SMART) multi use pathway will serve as the Great Redwood Trail. SMART staff will be responsible for construction and maintenance. 

While SMART was disappointingly slow to construct the promised pathway in the first 12 years of the agency’s existence (causing MCBC and our partners in Sonoma to withhold our endorsement for the agency’s 2020 ballot measure), there has been a significant amount of positive change in the last two years. The new General Manager, Eddie Cumins, has gotten the SMART pathway back on track, and the board has budgeted significant staffing and funding resources to make up for lost time. We expect to see groundbreaking of several remaining unbuilt segments of pathway in the next two years. 

Great Redwood Trail Agency

North of Cloverdale, the trail will be overseen by the Great Redwood Trail Agency. This is a new state agency born out of the Coastal Commission, whose job it will be to plan and implement 250 miles of trail. 

The GRT Master Plan has kicked off and will be complete in 2024, at which point funding will be sought to build the trail, starting with the most important segments.

Great Redwood Trail – Closer to Becoming a Reality

Imagine yourself riding north from Larkspur Ferry, through Cal Park Hill Tunnel toward San Rafael. Three hundred and twenty miles of bike paths and trails later, you find yourself in Eureka looking out over Humboldt Bay. Sounds like a dream, right? Well, that dream took a step closer to reality this October when Governor Newsom signed the Great Redwood Trail Act (SB 69) by State Senator Mike McGuire. 

Converted Railroads Lead to Seamless Bike Adventures

Imagine packing your bags, getting on your bike, and heading out of town on a quiet bike path. A few days later, that same path has carried you to another city hundreds of miles away, without having to navigate traffic the entire time. Is this the Netherlands? Denmark? Some future bike utopia? Nope – you can do that today between Pittsburgh and Washington, DC. Might we do the same in California?

Great Redwood Trail Bill Signed Into Law

Northern California is now much closer to realizing a vision for a continuous pathway spanning Northern California’s diverse and extraordinary landscapes from Marin to Humboldt Bay. Governor Brown last week signed the Great Redwood Trail Bill, setting in motion a series of plans & studies to complete the 300-mile pathway. “This is a once-in-a-lifetime opportunity,” said Jim Elias, MCBC’s Executive Director
