We have kayaks. Is this river kayak friendly for kids or too swift. Also, do you rent kayaks?

Easy River I know you can bring your own should not have any issue

Yes Casini Ranch rent Kayaks we have very, very aware children ROK two kayaks as long as they can swim and wear life preservers However there are areas on this river that are not safe for anyone to kayak

River is pretty slow... There are some rapids West on the river, but east (towards Santa Rosa) is slow. They rent kayaks and canoes (and other items) - for example a 4 hour 2+2 canoe rental was $45 for me this weekend (life vests included).
