The Zip-Line at this park is a HIT with my kids! We're from Livermore but my kids are always asking me to go to the "zip line park". Adventure Play Area is located within Don Biddle Community Park and it has lots of surrounding grass to play on, plenty of picnic tables, I always see a birthday party or group gathering on weekends. Not a ton of shade over the play areas so go early on particularly hot days. There's a bike path that the kids can ride scooters, etc. Tons of different play structures spread out so even when there's a lot of kids, no one is fighting for space/equipment. But the ZIP-LINE - that's the main attraction! It's super sturdy and safe, it has always stayed smooth and never gotten rusty/stuck like other places. Very well made - my 3 year old is able to sit and cling on while my husband LAUNCHES his down the line, and he'll go 4-5 feet in the air as it stops and he never is at risk for falling off. It's really well done.
