A lovely garden with lots of amazingly cool outdoor artwork. There are a few shops, a cafe as well as an area for holding events (think wedding!).  It is situated between Sonoma and Napa. About an hour's drive from San Francisco.

Mount Davidson

Address: Multiple entrances. There is one near 275 Juanita Way, San Francisco.

This is a good hiking trail right inside the south side of the City. The hiking trail is not paved and could get quite muddy when wet. But we don't have this problem lately due to the drought. After winding though a few sloped rounds you will see a big field with gorgeous view of the city. And on the other side stands the 300 ft tall big white cross. It's just amazing. And yes, it's dog friendly.
