Marina Park — San Leandro

A shoreside park with grass, two playgrounds, miles of sidewalk and a cool breeze from the way

Marina Park is situated along the San Leandro shore between Oyster Bay and Hayward Shoreline. There is so much grass, two playgrounds, group and small picnic areas, exercise equipment, miles of sidewalk space, a beach volleyball court (that usually doubles as a sandbox), a dog park, and fabulous views of the bay. 
The newer playground is on the south end of the park. It has a slide (only accessible by ladder), a swing set with bucket, standard, and chair swings, a zip line, monkey bars, a spinning post and merry go round and so many climbing opportunities on rope bridges, tunnels and webs. While it is near the parking lot, there is some fencing around that side.
The older playground has a structure, a swing set (bucket only), and a used-to-be splash pad that has just turned into climbing statues for the kids. The structure has three slides (double, sidewinder, and spiral), ladders, bridges, steps, activities, lookout bubbles and a small rubber underneath. This playground is also near the parking lot but separated by a small hill. 
There is a loop around the peninsula (the strip of land that creates the marina) with distance markers, more exercise equipment, great views of landing planes, and way way way too many squirrels for such a small space. DON'T FEED THEM!
If you cross the bridge at the end of the park it will connect you will the Bay Trail.
There are bathrooms and small parking lots near both playgrounds. If the parking lot is full there is street parking.
