Ride on it with my OneWheel and I had a blast! Got a bit lost at a certain point as the trail split at a park, but I found my way back on it! Totally fun trail!
We did this trail in Sept 2025. The completed portion of the trail is not very long and goes through the city of Santa Cruz. From the start and end points you have easy access to the Santa Cruz Beach Board Walk, and Natural Bridges State Park.
simple asphalt trail, unfortunately it rides by multiple homeless encampments and the people yell and threaten you to get out of their area. Needs more police patrols present, kinda nervous to use.
From the East end most of the trail was roadside but did have a paved bike lane. Several wineries to stop at including Concannon. However the main trail was closed. I posted photos.
Very popular trail that links up with the San Juan trail if you continue riding north thru Doheny State Park. Multi use with runners, bikers, rollerbladers, and folks that rent bikes or buggies from Doheny park.
Nice trail, flat and shady. There are a couple of big streets to cross but it is easy to pick up the trail again.
First time here. It's quite a wide trail, full of walkers, bikers and some runners and dogs. There are no restrooms on this trail, so make sure you're empty before starting. I will come again and will use this trail to get me back into running again.
Lots of shade along the way, a few dismount areas as you make it to where the path crosses the street.
This trail needs significant repair near Lightfighter entrance to 1 South. Some work done in last week or so but very inadequate. Also, trail ends at Del Monte, near dump. There is no safe trail from there to Castroville. If so, must be hidden.
We are new to biking and still finding our way. We started at the Livermore end and don’t recommend it. There is a lot of Urban riding on streets and lights to cross, we had to turn around a few times as the trail seemed a bit disjointed. So…. Start in San Ramon. We went on a Saturday morning about 8:30. The bushes are trimmed back to allow for bike riding. People were nice a courteous. I didn’t see any urban living that would have made me feel unsafe. We will definitely try this one again, but start farther north. Once we hit San Ramon, everything was great! We stopped at a Starbucks, had breakfast and used the bathroom.
