A short loop our of the small village of Port Costa. This trail offers views of the Carquinez Shoreline, and is a popular spot for spotting birds.

This trail starts in someone’s driveway, definitely going to pass on this one....

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.

I have a ny injury that I cannot do a lot of up and down hill walking. This place is great for me and the dogs.

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.
