We needed to get out of the city for a bit but didn’t want to drive too far, so we headed south to some of the protected land on the Peninsula. There’s a big slice of land on the Peninsula that is protected as state and county parks, fish and game refuge, and water district lands.

Sweeney Ridge is across the Peninsula from the airport and at the northern end of the chain of reservoir lakes that store water for the city of San Francisco.
