Jean Sweeney Open Space Park

"One of the nicest parks I've visited. The environment is clean, the atmosphere is friendly and there is a lot to do for children at the play place. You can tent a picnic space that has a grill and if it's not occupied you can use it without a reservation, just make sure to look behind the tables for a posted sign as it seems to be the only place that gets any form of marking(a printed piece of paper with information pertaining to if the spot is being reserved). The bathrooms are clean also, and there is a fountain for drinking water aswll as for pets."

"This park is now rated number one on our list, it's not that far away, with many activities to do, with a climbing structure, a giant sandbox, a small gated section for the little ones, a zip line, since the gazebo area was being used for a party I wasn't able to go check things out. I also loved that the bathrooms were right in the middle of everything and very clean. There is also plenty of grass to sit down and enjoy snacks and drinks with the young kiddos."

"Great park with unique ways to have fun! Zipline, swing set, play structure for little kids, big slide, logs to walk on, and a big sand box! Bathrooms are available. It is a great space and there is free parking. I recommend bring some sand toys and a hat. Most of the play areas are not covered so on a sunny day it can be hot. There is a bicycle path so you may also want to bring scooters and bikes!"

"Excellent, recently built park in Alameda on an old rail line. It has great climbing structures, a music play structure, a big slide for at least four kids to go down at once. Little kids area and a sand lot and a zip line for the bigger kids. Picnic tables, bathrooms, easy parking. Great choice for an hour or two with the kids. No food options so make sure to bring your own snacks."

"a review from @amom2kidsandapark Jean Sweeney Open Space Park is packed with history and kid-friendly fun. Jean Sweeney is a newer and not all the way complete open space park. The history of this park is inspiring. It was once a Railroad property about to become a housing development, but by the efforts of a local resident, Jean Sweeney, it became the beautiful park it is today. The maps said there will be a butterfly garden and a second playground but they don’t exist ... yet! The play area has a giant hillside slide that can fit many kids at a time, a zip line, a big sandbox (don't forget your sand toys), a log path for balancing practice (or floor is lava... which ever your adventurer prefers), a large mallet instrument, an even bigger rope climbing structure, and a hammock swing. There is also an almost gated in play structure that has three slides, ladders, steps, and a snacking table. In this area, there are bucket swings (no standard swings at this park). This playground is geared more towards tots/preschoolers. Right near this play area is a bathroom and a huge gazebo. Around the open space is a bike path (perfect for practicing bike skills) that doubles as a stroller or scooter path, grassy areas (perfect for picnics), and a future home for a butterfly garden and second playground. On the other end of the park is a coffee shop and around the corner is another great all-abilities playground, Littlejohn Park. This park can get very crowded especially on the weekends or school holidays. There is a parking lot but it can fill quickly."
