Choose from two trailheads and four hikes at San Bruno Mountain
State and County Park
Hike
One: Summit Loop
Beginning at the trailhead on the south side of Guadalupe Canyon Parkway, this
3.54 mile loop is a stunner when spring wildflowers are abloom. The narrow dirt
path, open to hikers and equestrians only, easily ascends to the ridge through
sagebrush, monkeyflower, coffeeberry, and coyote brush. Along the way you'll have
great views west and north. After crossing Radio Road, Summit Loop Trail drops
back down to the trailhead on a well-graded course, showcasing views of San Francisco
and the east bay.
High points:
A quick drive from San Francisco. Easy hiking. Great variety of plants. A native
plant garden is in development at the trailhead.
Low points:
You're never very far from civilization. Traffic noise from Guadalupe Canyon Parkway
is present for much of the hike.

Hike
Two: Bog Loop
This short and easy hike is a good choice for folks hiking with kids. The .8 mile
loop (on which bicycles aren't permitted) begins at San Bruno's main trailhead,
just north of Guadalupe Canyon Parkway. Bog Trail winds levelly on a dirt path
through blackberry, coyote brush and coffeeberry, with willows and dogwood thriving
in moist spots.
High points:
A great quick get-away hike if you live nearby. Excellent bird watching. Picnic
area and restrooms make this a great family outing destination.
Low points:
If you don't know what a bog is, take this hike during the rainy season.

Three: Saddle Loop
This 2.9 mile loop is the most popular circuit at San Bruno. Starting at the trailhead
just past the park entrance, Saddle Loop Trail skirts the picnic area and then
climbs easily through grassy hillsides. Good wildflowers in spring, although much
of the area in this part of the park has been overtaken by gorse, a non-native
shrub. Outstanding views of San Francisco, and on clear days, much of the Point
Reyes peninsula and the Farralons. The loop finishes on a level paved trail, winding
through eucalyptus.
High points:
A good exercise loop if you live nearby. Nice wildflower display in spring.
Low points:
Civilization continues to infiltrate any wilderness at San Bruno, and more than
anywhere else in the park, along this trail you'll feel the crush.

Four: All Access Hike/Loop
A .3 mile level portion of the compacted earth Bog Trail is accessible to wheelchair
users, and the short path can be extended to a .8 mile loop on paved flat Old
Guadalupe Trail (the path connecting Bog and Old Guadalupe may be too great of
a grade for some wheelchair users). The vegetation is a mix of native shrubs like
coffeeberry and coyote brush and non-native plants such as eucalyptus.
High points:
Bog Trail is an excellent path for wheelchair users. Guide wires assist sight
impaired or walkers with limited abilities.
Low points:
Can get muddy in winter.
