Tilden Little Farm in Berkeley
Oh how I wish I has remembered to take pictures for you all! Deep in Tilden there is one of the best kept free east bay treasures: Little Farm.
These animals are living in the farm equivalent of the Four Seasons (except for the loud, bothersome kids trying to pet them I guess!) There are cows, goats, hogs, chickens, etc. Bring celery or lettuce and watch your kid squeal with delight as that big cow tongue grabs the treat. So fun!
It is a popular spot so expect a lot of kids and some parking issues (might have to park and walk a ways). But there are clean(ish) restrooms, lots of great picnic spots and a playground right there. Such a great, free outing.
