Guajome Lake, while not an awe inspiring wonder of the world, is a very nice overgrown park in the middle of urban sprawl. It's big enough that you forget you are surrounded by freeways on all sides, and can just wander around taking in the native plants on the numerous trails carved throughout There is a playground and picnic area overlooking the lake, great for birthday parties or get-togethers. You can fish in the lake, but I don't think swimming or boating is allowed (it's pretty small, and not pristine). Geese and ducks roam around the lakes edge and appreciate any crumbs you throw their way. The campground is fairly large, and always full. I've never camped there, but it seems nice and will accommodate trailers and tents. 1 side of the park is closer to the freeway and there is some graffiti present, otherwise the park is very safe and easy to traverse.
