OK - so we biked it this time but we have walked it plenty of other times! This is a great trail for families. We can take our kids out and do any section of it and make it as long or as short as we want it to be.
I have walked it from the Overlook Park all the way to San Gabriel and back and biked it as well. There are always plenty of walkers and bikers and there are plenty of places to stop along the way. I think this rivals the Lady Bird Lake Hike and Bike trail!!
