Overview
Golden Gate Park is 1,017 acres of legitimate variety — the Koret Children's Quarter is the oldest public playground in the United States, the bison paddock has a small herd that has roamed the park since 1891, and Stow Lake's paddleboat rentals put kids in the water on a weekday afternoon for under $35. For an active family, this place rewards repeat visits with different anchors each time rather than one exhausting loop.

How to Do It
Parking near the Koret Children's Quarter is east of Bowling Green Drive by the lawn bowling building — that lot fills first on weekends. Street parking on Kezar Drive (around 631 Kezar Dr) adds a short walk but is reliably available. By transit, MUNI routes 7, 33, and the N-Judah drop you within a few blocks of the eastern end of the park; Stanyan St & Waller St is the closest stop to Koret, about a 6-minute walk to the playground.

A practical route for a half-day: start at Koret (the concrete slides and wave climbing wall will hold kids for 45 minutes minimum), then walk west on JFK Drive to Stow Lake for paddleboat rentals or just the loop path around the island. The bison paddock is further west near 38th Avenue — worth the drive if you're already heading toward Ocean Beach. The Japanese Tea Garden and SF Botanical Garden sit in the heart of the park between 8th and 9th Avenues and work well as a calmer second act once the kids have burned energy on the playground.
Tips & Tricks
The concrete slides at Koret require cardboard to slide fast. Pieces are often scattered around, but they go quickly on busy days — stuff a flat sheet of cardboard in the car before you leave. The wave climbing wall is separate from the main slide structure and tends to be less crowded; it's where the stronger climbers want to be.
The JFK Promenade runs car-free for 1.5 miles along John F. Kennedy Drive from Stanyan to Crossover Drive, and it is exactly the right surface for kids learning to bike or scooter. On weekends it extends further toward the ocean. Bring their wheels.
The SF Botanical Garden offers free entry before 9:00 a.m. daily and is always free for SF residents with ID. The redwood grove and the bamboo grove are legitimately immersive for kids — the scale of both stops them in their tracks. Adult non-resident tickets are $17.25 at the gate; skip the online surcharge.
The carousel at Bowling Green Drive runs Tuesday through Sunday, 10 a.m. to 5 p.m. (closed Mondays, weather-dependent). Rides are $2 for adults, $1 for kids 6–12, and free for kids under 5 with a paying adult. The 62-animal menagerie includes a dragon, a camel, and a goat — worth calling ahead (415-231-0077) to confirm hours in winter or on foggy days.
Weekday mornings between 9 and 11 a.m. are a different park than weekend afternoons. The playground is walkable, the paths are quiet, and you can actually hear the waterfowl at Stow Lake.
Planning
The park itself is free. Stow Lake paddleboat rentals run $26/hour for a rowboat, $32.50/hour for a two-passenger pedal boat, and $45/hour for a large four-to-six-person pedal boat; rentals are available Monday through Friday 10 a.m. to 5 p.m., weekends 10 a.m. to 6 p.m. The SF Botanical Garden charges $17.25 for adults, $9.25 for ages 12–17 and 65+, $5.25 for ages 5–11, and free for under 5 and SF residents with ID. The carousel is $2/$1/free.

Golden Gate Park works in every month — summer fog keeps it cool for running around, fall is crisp and less crowded, and winter weekday mornings are genuinely peaceful. July and August bring more tourists and weekend crowds; arrive by 9 a.m. or go weekday. Skip the park on the same day as a major event (Outside Lands festival in August closes large sections).
Bring layers regardless of season — the fog can roll in from Ocean Beach within 20 minutes of a sunny start. Water, snacks, and a change of clothes for water table / paddleboat scenarios. The Koret playground has restrooms near the Sharon Building.
