The view of the reservoir starts right away so it's a good place to take the less able as it's low commitment. Parking could be an issue but it seems busy enough that someone is always about to leave. All paved at this area so you can blade, bike, or push a stroller.
It was easy to find, just drove to where google said it was. I look forward to exploring more of this trail.
Would get 5 stars except that parking is rather difficult. Park by the off ramps either in millbrae, San Mateo or trousdale exit. Gorgeous views of reservoir. Watchout for bikers and moms with strollers. Otherwise, there is nothing like N early morning walk or run. Bobcats, foxes, coyotes and deer. Rattlesnakes during the summer--just don't walk up to them and you'll be fine. Apparently mountain lions but haven't seen any.
Meditate , Relax, and Enjoy!
