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.
the trailhas been closed for years big disappointment
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.
