San Francisco Botanical Garden at Strybing Arboretum
One of the best picnic spots in a very picnic-friendly park, the 55-acre arboretum specializes in plants from areas with climates similar to that of the Bay Area. Walk the Eastern Australian garden to see tough, pokey shrubs and plants with cartoon-like names, such as the lilly-pilly tree. You don't have to go to Muir Woods to see the largest living things on earth: the botanical garden boasts a 4-acre redwood grove in the heart of the city. Kids gravitate toward the large, shallow fountain and the pond with ducks, turtles, and egrets. Free public tours are given Monday, Wednesday, Friday, and Saturday at 1:30, with an additional tour Saturday at 10:30. No reservations are required.
