Is this a good place for the little ones to swim? Spots where there aren't to many people? Thx in advance

I wouldn't let kids under 6 years in any river without a life vest and make sure that the water isn't too cold

I would say that there's different places that you could find along the river off of Clackamas Trail as long as there is adult supervision the littles should be okay as I go for long walks on that trail lots of times to get away from home once in awhile. So yes there's good spots where you can take the little ones to play in the water. I hope this was helpful for you and I'm glad I could help out.
