Okay, this is not a secret park, but currently very few Oaklanders know about this spot. This park is in west Oakland at the Port of Oakland. Go down 7th Street, past the main Oakland Post Office, under the freeway overpass and you will find Middle Harbor Shoreline Park. Here you will have dead on, up close views of San Francisco, sprawling lush grass, concrete paths perfect for bikes or scooters, picnic tables and much more! Every time I visit this park, the park is quite empty, giving me and my family plenty of room to spread-out. Because the park can be windy bring a kite and a jacket. Go visit this wonderful park!...and shhhh, let's keep it a secret, only tell your special friends.
