San Bruno Mountain Watch: Natural History and Ecology Hike

San Bruno Mountain Watch regularly leads hikes on the first and third Saturdays of each month.  Learn about the history and ecology of San Bruno Mountain.  E.O. Wilson the legendary ecologist called San Bruno Mountain an "Island of Biodiversity" and has identified as one of 18 biodiversity hotspots on the planet.

These hikes are rated 2B by the Sierra Club (less than 6 miles long, 1000+ft. elevation gain.)  We typically go at a moderate pace with many stops. The terrain can be steep at times, but we're never on a forced march. Walking poles can be very useful, and you will get some exercise! Bring water, sun protection, and a snack or lunch. Wear sturdy shoes, long pants, and layered clothing.

We will leave the main parking area at 10 am, and return by about 1:30 pm.
