It is best to visit Golden Gate Park on Sundays, when cars are prohibited (shops rent bikes and skates near park entrances; rentals are also available at Stow Lake). A picnic spot can be found at one of the many lush meadows; hot dogs, popcorn, ice cream and the like are sold at Stow Lake, the Carousel and other locations. It is a good idea to pick up a map of the park (available at bike rental shops and also McLaren Lodge (weekdays only), at the Stanyon Street entrance; the park's serpentine roads are charming, but it's easy to get lost. Information: (415) 831-2700. A free shuttle crosses the park every 15 minutes, making 15 stops, on weekends and holidays until Oct. 26; (415) 831-2727;
