One of my kids has ADHD and loved Kennolyn (in Big Basin near Santa Cruz). It is GORGEOUS and there are kids there whose parents went as well. It's close enough so if you need to do a middle of the night pickup you can but far enough that it seems like a magical enchanted forest. It's pretty popular (and kind of pricey) but it was worth it for the joy my child experiences year after year there.
