Berkeley's Tilden Park
Little Farm, Nature Center, Steam Trainx2 & Carousel
A little more than an hour over in the East Bay, Berkeley's Tilden Park is a wonderful day trip. This was a big hit for kids and adults. The Little Farm is a working farm with cows, goats, bunnies, chickens and more. Bring celery or lettuce to feed the hungry cows. Admission for this area is Free.
Not too far away there's also an Environmental Education Center with permanent nature displays, family walks, and craft workshops. There's also an enclosed playground and picnic benches for lunch.
Nearby Jewel Lake is an easy loop to work off lunch. Great for toddlers but not stroller friendly. All these attractions are together at one stop. There is a parking lot and flush toilets at the EEC.
Another big stop at Tilden is the Steam Trains. Saturday and Sundays, 11A-5/6p. Rides are affordable and if you go on a Sunday, 12p-3p the local steam train enthusiasts Golden Gate Live Steamers also run their hobby trains nearby, so 2 train opportunities. Tickets for adults and children are $3.50 (children under 2 years old ride free). A five-ride ticket costs $14.
Lastly, if there is still energy to continue, Tilden also offers Merry Go Round rides with a cafe. Open Fri, Sat and Sun, 11A-5P. Tickets are $4/ride or $22/7.
