Best trail I didn't know about. Do not follow the directions map, look up the staging area and drive there

A reason to visit Port Costa. Great views of the Carquinez strait and Benicia. No parking at trailhead. So park at Canyon Lake Dr, then walk up Prospect Ave.

Very relaxing trail perfect for beginners. Scenic and close to the water. Good trail for pet owners. I highly recommend for locals.

Wanted to like it more, but spent most the hike dodging cow pies and mud puddles. Nice views of Benicia here and there and a good constitutional close to home, but otherwise not worth a revisit. Is no one else terrified by the cows?

Nice easy trail with sweeping views of plains and a good mix of light forestry. Extremely quiet and relaxing.

Nice jaunt, great for a short hike, nestled near scenic old town of Port Costa. End up at Bull Valley Restaurant or Warehouse Bar after your hike. Shhhh. Not overrun with tourists ...... yet. Let’s keep this jewel a secret.

Nice, short and relatively easy hike with great views of the Benicia bridge, Carquinez straight and Carquines bridge. Especially nice during spring with green hills and a few wildflowers.

Such a beautiful trial but very hard to find the entrance as it’s located in a small neighborhood on top of a hill. You must park in the parking lot in the town and walk up Caynon Lake Dr and take a right on Prospect Ave and follow that up. There you’ll reach the trail. Not good for strollers but easy to backpack with a baby. Very dog friendly, you can take your pup off leash but make sure they’re on command as others have dogs both on and off leash. The views from the top are GORGEOUS! And the town is so cool.

You need to go to the Bull Valley staging area to access the loop. Once there you will double back the way you came on McEwen Rd. Follow the trail along the fence line until you come to a gate that you leads into the town of Port Costa. Not a bad hike.

We started from the Nejedly Staging Area in Martinez, hike along the Carquinez Scenic Drive and the George Miller Trail, and continued to Port Costa Staging Area and return. This is an out and back hike along paved walkways/roads for a total of 7+ miles, and a total ascent of 575 feet.
