The Alamo Canal Trail can be found adjacent to the man-made waterway, the Alamo Canal. It is a short but useful trail, connecting riders and runners to other trails, like the Iron Horse Regional Trail.

Wide well paved flat biking trail (sometimes shared with hikers) following a former rail line along the San Ramon Valley from Pleasanton via Dublin and Walnut Creek to Concord.

South of the trail bridge marking the Alameda -Contra Costa County line a couple of shade structures provide some protection from the sun along this largely shadeless and tree-free section of the San Ramon Valley Iron Horse Trail

More narrow and gently winding but quieter than the Iron Horse Trail, this is a nice alternate or loop option and links up again with the Iron Horse Trail

Part of the long North-South regional trail along the former San Ramon Valley railway, now Iron Horse Trail

The North-South Iron Horse trail offers excellent options for loops via east-west trails, like here the Arroyo Mocho Trail running east to Livermore, where for example the return loop can be closed via the Arroyo Valle a little further south, though the trail there is more often interrupted but can be followed with occasional sections on paved neighborhood streets.
