The Conejo Recreation and Park District maintains over 4 dozen parks in the Conejo Valley. These parks contain over 20 tennis courts, close to 30 basketball courts, dozens of softball/soccer fields, nearly 150 swing sets, around 100 slides, dozens and dozens of play structures and jungle gym equipment and countless other fun things for the kids.
Some observations below based on personal experiences:
Peppertree Playfieldshas multiple playing fields for soccer, baseball, etc. and is a popular spot for locl team sports. It has 4 restrooms and is a nicely maintained park. It has a decent sized play area and the smaller kids' play area was updated in the latter part of 2008).
Conejo Creek Park - North in Thousand Oaks behind the Thousand Oaks Library is easily my kids' favorite park. It is large, has nicely appointed play areas, plenty of restrooms and parking and a large duck pond with a 720 foot creek joining them. This park is officially known as "The Ducky Park" in our household. The playground also has a NEOS, an interactive, electronic game with flashing lights, music and sound effects.
If you are a duck fan, Conejo Creek Park - North will not disappoint you. There are more Ducks per square foot here than the Anaheim Ducks locker room!
Borchard Community Park in Newbury Park (Reino Road and Borchard Road) is another large park with multiple playing fields, restrooms, separate play areas for older and younger kids that are quite interesting and nicely updated, tennis courts and a community center where hundreds and hundreds of CRPD classes are held each year.

Conejo Community Park in Thousand Oaks (Dover and Hendrix) is a nicely sized park that is well known in the summer for the CRPD free summer concert series...that alone makes this one of my favorite parks as it is a perfect venue for outdoor summer concerts on the grass. In November 2008 a brand new $550K play area was completed between the community center and the Botanic Garden. It includes a rock and rope climbing area and a skateboard "simulator" for 5 to 12 year olds, along with a separate play area for the younger set.
Rancho Conejo Playfields on North Ventu Park Road in Newbury Park has a large expanse of grass for soccer games and a baseball diamond. There is a fun kids area there and 2 restrooms. Parking lot is fairly small. A fun place for the kids to run around. Not a lot of fully grown trees at this park.
Old Meadows Park in Thousand Oaks (1600 Marview Drive) is hidden away off of Erbes Road in Thousand Oaks. Kind of a quiet, low key, fairly undeveloped park that is geared towards the local neighborhood and younger children.
Banyan Parkin Newbury Park (3571 Erinlea Ave) is a small neighborhood park with 2 restrooms, small covered picnic area and a kids playground area.

Oak Canyon Community Park is located at 5600 Hollytree Drive in Oak Park at Kanan.

Designed by Shane’s Inspiration, a non-profit organization that designs and builds universally accessible playgrounds, and opened in October 2006, Brandon’s Village features playground equipment is over 70% independently playable for children with disabilities and also provides meaningful and stimulating play opportunities for able-bodied children.
We visited the park on Friday, January 1, 2010 and the kids had a blast. There is a HUGE play area for 5 to 12 year olds with many unique features I haven't seen in other parks, such as a unique roller-driven slide and a large "swaying" ship that we spent about half an hour on. There is a separate play area for younger children. My 4 year old was completely entranced with the play area and didn't want to leave. The video below doesn't quite do the place justice but will give you some feel for how cool Brandon's Village is. This is a "must visit" place in my opinion if you live in the area with kids!
Your kids will fall in love with the nooks, crannies, steps, bridges and places to hide in this play structure. There are also swings and things to climb on. The park itself is 2 blocks long and one of the oldest parks in Santa Barbara. It is next door to the beautiful Alice Keck Park Memorial Garden. Plenty of grass, spectacular, large shade trees and much more make this a perfect picnic lunch stop when you're in town.
Located at 3700 Avenida Simi in Simi Valley, Rancho Tapo Community Park is hidden away north of the 118 freeway between Sequoia Avenue and Tapo Canyon Road. While not a huge park by most standards, it is a nicely balanced park with something for everyone, including several play areas, splash pad, covered area for gatherings, nicely appointed fitness circut area, playfields, basketball and a peaceful Veterans' Plaza with pond in memory those who have served. Best of all, this is a very flat park with a nice, 1/2 mile walking path that the kids enjoy riding their scooters on. We like this park! Visit www.rsrpd.org/park/rtcp/rtcp.html for more information.
This is one of the only local parks I can think of that has one of these metal spinner things (official terminology). I didn't last long on it as my kids pushed me around. Almost lost my lunch.
Rancho Simi Community Park, located at 1765 Royal Avenue, is one of the largest parks in the area at over 33 acres. It has 2 playgrounds, 8 tennis courts, basketball, pool, horseshoe pits, a lagoon with ducks and plenty more. In recent years it has been home home of the annual Simi Valley Days event.

The park opened in Spring 2010. Check out the video below to see how large this park is.
This park is so new that Google Maps and the other online mapping services don't show it on their maps yet. But THIS GOOGLE MAP shows the large area adjacent to the 101 where the park now resides. You can't miss it.

Sumac Park is located at 6000 Calmfield Avenue in Agoura Hills. It is a small neighborhood park that was recently (summer 2010) upgraded with a nice, new play structure. There is a handful of parking spots and plenty of street parking, restrooms (these are pretty old style but functional) and a nice, flat grassy area. More information at www.ci.agoura-hills.ca.us/index.aspx?page=64.
Today we stopped by the Oxnard Beach Park on South Harbor Boulevard, South of Wooley Road and next to the Mandalay Suites Hotel in Oxnard. I was quite impressed with this awesome pirate-themed play area that looked pretty much brand new (we visited on January 2, 2010). The structure is huge and my boys had a blast with it, particularly the 4 year old. There is a larger structure for 5 to 12 year olds and a smaller one for younger kids.
And of course this park is just a short walk to the beach, where we also spent time digging holes, building sandcastles and running from the waves.
The park has a large grassy area, restrooms, BBQ grills, bike paths, etc. Parking costs $1 per hour and I paid it, though it didn't appear as if anyone was monitoring. Definitely worth checking out!
