Great paved trail with beautiful views. It has lots of hills so be prepared for those steep inclines. Parallel to 35 and 280 so expect parts of the trail to be a bit noisy. Very nice, groomed paths, benches with awesome views, shade in some parts, has a bathroom but I’m not sure if it’s functional. Never seen any animals besides birds or lizards on this route. Good amounts of parking at either end!

The trail in the map here actually includes the northern tip of Sawyer Camp Trail -- the south end of San Andreas Lake. The San Andreas Lake Trail itself contains two parts: the northern part is a paved road next to San Andreas Lake, starting at San Bruno Ave and Skyline Blvd and ending at the west end of Hillcrest Blvd; the southern part follows. It's a narrow primitive trail in the woods next to Interstate 280. Slight curvy and no spectacular view. Overall it's a short easy walk, but I prefer Sawyer Camp Trail, which is three times longer.

Very flat 7 mile stretch which I got to do with a fellow pregnant friend. We are both in our third trimesters and it was perfect for us -- there were a number of benches and restrooms! Thank goodness.

The paved path runs parallel to Skyline Blvd and there is a lot of noise from the road. It's scenic, but you don't really get close to the lake as the watershed is fenced off. The views of the lake are scenic and the part close to the damn is nice. I think the Sawyer Camp trail further south is much better. There is very little shade. There are restrooms at two locations and a water fountain by one of them.

I've only walked the San Andreas Trail portion from its start at San Bruno Ave @Skyline to the Trousdale/280 exit in Millbrae. That's a little over 5 miles roundtrip. Mostly flat & paved, it's an easy walk with a beautiful view to the west (the reservoir). The drawback is the incessant, loud traffic noise from 280. And no dogs allowed so I can't bring my best friend. There isn't anywhere to picnic on this stretch & only one place to sit, but this trail is all about exercise.

Traffic noise. The San Andreas Trail is the northernmost segment of the Crystal Springs Regional Trail. From the start of the trail at San Bruno Avenue to Larkspur Drive the trail is paved and mostly very level. From Larkspur Drive to the end of the San Andreas segment at Hillcrest Boulevard the paved trail turns into a true dirt trail. Hiking boots are needed. This portion makes up 20% of the total San Andreas segment. As you walk south you have the beautiful scenic San Andreas Lake and Sweeney Ridge on your righthand side. To the left you have Route 35 and Highway 280. Traffic noise. You feel somewhat caged in as there are fences on both sides of the trail. The traffic noise can be loud enough at times to drown out conversations with your hiking partner. Sometimes that could be a positive. The main purpose of the trail is aerobic exercise. Yes, there are a few pine trees, ducks, and deer can be sighted at the northern end, but most walkers are thinking of calories being burned. A restroom on the trail is neat and clean and there are benches to sit on as you enjoy your lunch and view the lake. Traffic noise.

Not recommended unless you're going for a quick bike ride. There are two paths here: one that runs along the lake and one that runs along Highway 35. The path along the lake is closed, which means you have to resort to the other path. Since that path runs along the highway, you get to enjoy the pleasant noise of car whizzing by while on your hike. If you must be on this trail, bring lots of friends or generous headphones.

I only go here for an exercise ride since I live just down the street. Nice place for joggers and roadies. Pretty much all paved trail. Don't expect any mountain biking fun.

Walked on the paved trail for about 2miles out&back. It had a nice view and weather, but it was too close to the freeway for my liking. Kind of noisy, but I tuned it out after awhile. Walked up the other side of larkspur exit(south of it) on the way back for a little and enjoyed it. Nice dirt path & more secluded. Going to give that side a try next time. Watch out for the poison ivy!

Paved trail probably good for a quick bike ride. No access to the reservoir & sticks way too close to the 35 for casual hiking. Exposed most of the way down.
