The Bog Trail winds through San Bruno Mountain Park's "Saddle Area," a wet, riparian area at the foot of the mountain. The chilly Pacific air here rumbles with the wash of jets departing SFO. It's often foggy or cloudy, with a breeze blowing off the ocean. A dense, low canopy of sedge and rush hedges most of the trail, while cool leather ferns grow in the shadier nooks. Many birds--wrens, finches, sparrows, and more--can be heard singing. You may even spot a covey of California quail scampering beneath the brushwood.

The trail begins a short distance west of the parking lot. At the trail head you'll find two paths, both marked "Bog Trail." Bog Trail is a loop that connects back with itself at the trail head, so you may travel either path and end up right back where you started. The trail straight ahead is broad, gravelly, and well-manicured, while the trail to the left offers a little more adventure.
