Centennial Trail is a 12.5 mile lightly trafficked out and back trail located near Pleasanton, California and is rated as moderate. The trail is primarily used for hiking, trail running, and road biking and is accessible year-round.
The Centennial Trail is a walking path that follows the Arroyo de la Laguna. This unpaved path connects several parks, and is a great way to navigate through Pleasanton.
Not bad. It's a long, flat path that follows along the creeks. The surface is mostly gravel, but paved at some parts. The bridge was closed at Arroyo Mocho, blocking the path north toward 580. So I added some distance by going further east to make up for it. You can continue eastward along the middle trail until it intersects with Stoneridge.
The trail was lightly trafficked. I passed some joggers, walkers, dog walkers, and a couple of bikers. I biked the whole thing with my Trek 7.2 with trail tires.
